That sound like a problem with psu to be sure get yourself a psu tester you can get a good one for around a 10 on ebay also take a look at your mobo to see if there is damage there also check your ups and safety hub.

Hello,

I had a lightning strike and I think my Power Supply may be shot.

I had it plugged into a cheap surge protector, but I don't trust it.

When I plug it in, directly to the wall socket, the green LED on the back of the power supply just flashes constantly. But when I try to turn the computer on, absolutely nothing happens.

I tried a new power cord with no luck...same thing.

Might there be a reset switch in the power supply, or does this flashing green light mean that it is dead.

Thanks...I appreciate your help

Matthew

This happens: http://www.youtube.com/watch?v=IfY4A8gQ1bE

The horizontal lines disappear shortly after removing the power supply, and come back when it's reconnected.

Observations and steps taken:

- The computer has been connected to multiple power supplies in different rooms. This behavior happens regardless of the power supply.

- This doesn't start right away when the computer boots up - only after some time.

- It also doesn't seem to happen in safe mode, but I haven't tested it under heavy processor load in safe mode.

What is happening? What steps should I take?
 

A:Computer monitor has flashing horizontal lines when power supply is connected

A system restore resolved this temporarily, but the Windows Update which installed immediately afterwards caused it to start happening again.

A:hp computer not start power green lite flashing

Does the HP logo shows when you start it? If yes, maybe your OS is corrupted. Try reinstalling it. If not, try reseating the RAM and removing the battery and turn it on (make sure it's plugged in when you turn it on). Still not solved? Let a technician handle it.

My power supply stopped working, so I replaced the power supply and the PC will start. There is power going to the motherboard, the fan is working fine, but the PC will not boot. The light on the front of the PC never turns green, it remains orange. Everything is plugged in OK. There are no beeps when the PC is trying to start. Any Suggestions?

You need to be more detailed. At least CPU, video card and of course what PSU you replaced the old one with.

Hi there,

I've been having some power issues with my laptop for a while. For some time now, my laptop has been constantly losing power and shutting off, regardless of whether I am running off the battery or the power supply. There does seem to be inconsistency as to whether the computer is getting power from the supply (it will be plugged in and off, and sometimes the light that indicates that it's charging will be on, and other times it won't.) I've also noticed that the power supply, as well as the bottom of the computer, get extremely hot. Sound like a bad power supply, or something else? I just think it's weird that it dies regardless of whether it is running off of the battery or the power supply. Perhaps the battery isn't getting power and it thinks it is?

Thanks for your help!
 

A:Laptop will not start. Bad power supply?

You don't tell us which laptop you have, but the odds are that the power cable connection into the laptop has failed because the socket is coming off either the power controller or the motherboard. An unstable connection can arc and cause heat. You need to get this fixed before it does any more damage and becomes unrepairable. A decent laptop repair should do this for less than $200/100 or local equivalent.

Good day everyone maybe someone can give me some light on this issue I have identified this as being a power supply problem however it may be related to another component within the mother board This is what happens Since a couple of weeks back I ve noticed that my machine sometimes just won t boot up The specifics of the PC hardware I assume are unimportant at the moment but just for the sake supply Bestec Power 250-12Z start ATX won't of explanation let me tell you that we are talking about a tower PC de-branded HP P which as you all know that means it has no support from its OEM Anyhow the problem is that sometimes it just did not start up by pushing the power on button Some of you may think it could be due to a problem with a loose cable or the sort believe that is not the case Well this has been Bestec ATX 250-12Z Power supply won't start going on and off but since yesterday my PC has been even more stubborn to power on Today after even removing all external cables and trying a few things it did not power up no fan no sign of life but just a green light I assume it s an LED just below its power connector that while the problem existed it was blinking green I even removed any cable from the HDD DVD and any other power connector and still the same behaviour Ok after trying this and that I could finally make it boot up by the way I m writing this from the same machine in mention but I m affraid this may happen again and probably it s a sign of something worse to come or just break completely Another thing I noted is that when the light is solid green I can power up which gives me the impression the power supply was in a sort of locked state I ve been looking for any manual or troubleshooting guide from the manufacturer Bestec in order to better identify the issue but have been unlucky so far I wouldn t like to replace it without having more info regarding what is causing it Any ideas or anyway I can find this power supply troubleshooting manual Thank you so much for any reply towards solving my issue regards Moris nbsp

A:Bestec ATX 250-12Z Power supply won't start

That Bestec is really a piece of crap. Go get a Fortron 350W or higher PSU, and your problems are over. Check first if the PSU to motherboard connector is a 20 or 24-pin version and get the appropriate 20-24 adapter with it if necessary.

I have a Packard Bell computer S610-Pentium 233mmx that had the power switch toggles on/off repeatedly by a 2 year old. Now the system will not start. The cpu fan and the power supply fan start to turn then stop when the main power switch is turned on. I figured it was the power supply, replaced it and the new one does the same thing. Any ideas would be appreciated.

A:pc won't start - power supply failure?

Okay, this could be two things: the power-supply or the monitor, both of which you'll need to find another of, at least for testing purposes. If you get the power-supply then make sure it's the same type and make (look on your computer and give us the MODEL number for your specific computer, this'll give us the specs we need to determine what kind of power-supply you need). I don't think it has anything to do with your game, but it could very well have something to do with your graphics and/or your video card as well. Is it the power, or the dv15 pluggin (that's the plug where you hook it to the comp itself, NOT power, the other one) that messes it up?

Most likely this is a power-supply matter as you pointed out and that'll require a replacement. Those things cost alot, so if you can find a used computer at the dump or something or go to a local hospital and buy one for cheap, or have a friend with one they don't use cuz it's broke or something i'd do that, but make sure it's compatible!

God Bless and In Him,

Eric

Hi. Recently got a brand new PC on an auction website and have had nothing but trouble from it. Today it's PSU started making a continuous extremely loud whining noise like a jet-liner taxiing on the airport, and the whole system was going crazy; the OS kept crashing etc, and before long it crashed again and could not be restarted. This prompted some Web research on the PSU (an ISO-500PP 420 Watts) and was not surprised to see that they have got an appalling reputation with fake "technical specifications" on the label. Am not writing this for help advice, as the PSU is stuffed. Primary reason for writing is to warn people, if you are buying a PC make sure that the PSU is not an ISO!!!

So I just recently purchased a new desktop as my laptop fried. I bought this desktop with getting a new video card and power supply in mind. I purchased an ATI Radeon HD5750 which requires one of those 6 pin power cords. The new power supply had what I need.

When i switched out the old 250W for my new 500W, I received no results. The computer would turn on, all fans would run but I would get nothing on my monitor. The motherboard green light would also turn on. When i swapped back to the old power supply, everything still works great. Any troubleshooting tips? Im told that this might not be a great power supply either. Thanks in advance.

Hi,

This is a problem I had since a few months, but back then it wasn't that irritating. Sometimes when I tried to start my computer it would start up mechanically, so to say; all the fans were working and so were the HDDs, but not the BIOS. Nothing would happen, and the monitor was ever idle. A simple cold reboot usually solved the problem.

Now, like I mentioned, the problem got serious. The computer won't start at all, i.e. nor the fans, nor the monitor, nor the HDDs will ever start up. It just keeps restarting itself every second without any enhancement. I also found a solution for this problem by setting the power supply to 0, and then back to 1 after a few hours(!). Restarting after just a few minutes doesn't work. What's the matter? Have you ever encountered such a problem?

Even more weird, I've found if I jump the green and black wires on the 24 pin, pc starts, remove the jump, pc shuts down, then I'm able to jump the PWR switch and the pc starts as its supposed to. I've tested this 3 times and it never fails
Why would the switch only work after jumping then removing the jump on the 24 pin???

This is an attempt at understanding what makes a power supply wake up.

I believe that you have to short a couple pins in order to make this happen.
Anyone know what pins to short?
Or am I on the wrong track?
I have a Power Supply checker that causes the PS to come to life when it is plugged into the molex connector. However, i am curious if, in the absence of this tester, if I could check the PS with a multimeter.

Probably need new power supply as on/off switch on back of computer does nothing (won't turn computer on or off by that switch).

However, the ritual I seem forced to follow makes me wonder if that is my only problem--- Let me explain:

Hitting the switch on the front of the computer doesn't usually result in starting the computer-- but what does start it is to unplug the chord from the back of the computer and then plug it back in (unpluggin/pluggin in at surge protector doesn't usually have same results).

I leave machine running 24/7 and it works fine--- however, I am concerned that I want it repaired before it fails altogether.

Your help would be appreciated

A:Switch on Power Supply bad-- and need to plug cord in to start

Having to remove the cord to start is usually indicative of a PSU fault.
Though unplugging or turning off should have the same effect.

PS a "chord" is a series of three or more musical notes...

Here is my story First off all I am building computers for a couple of years now and I know what anymore Supply Switch closing with Power won't after it Computer start I am doing but This problem arrived the other day after changing my case Days Ago I bought A new Case and a new Burner for my Computer I unintalled everything and installed it in my new Case I plugged everything back up and was on my computer again without any problems I used the reset button but it was behaving oddly the computer was still running but the monitor turned itself Computer won't start anymore after closing it with Power Supply Switch off So I though that maybe I had installed the reset Switch the wrong way I couldn t stop it anymore so I closed it with the Power Supply Switch So I opened my case to see if everything was ok Everything was as it was supposed to be I played with the connectors a little bit to make sure they were well connected I tried running the computers again but it wouldn t start It didin t make a noise no fan running no BIOS nothing I was very afraid to have killed my Power Supply or MOBO by closing it the wrong way I though that maybe it was just the power button of my new case that was the problem so I connected the Reset Switch connector in the Power Switch I tried turning it on and it worked I was very releaved that it was just that problem So I left it opened all night and went to work I also accesed my computer remotely from work almost all day But Last night when I finally came home the computer was closed I though it was weird but opened it again and went to see a couple of things on the net Went out for min max with my GirlFriend When I came back the computer was closed again and it wouldn t start again like it did the day before So I opened it again checking the reset and power switch button But now any of the didn t work anymore I thought that it couldn t be the PSU or MOBO because last night I was able to get it back up by switching the Power and Reset switch I started to unhook every power cable from HD to CD and floppy even the case fan Nothing Took out the Sound card and Video Capture Card Nothing Unhooked the HD and DVD Burner and floppy NOthing Took out the Video Card I also plugged out and plugged back in the Mother board and CPU Power connector from the PSU to be sure that they were well connected Nothing happened I even took out the Front of the case to look at the Power Button They looked ok but I am no expert in that I also took the MOBO battery out to clear the BIOS Now my computer is dead I can t do anything to make it work I am thinking that by closing the computer with the PSU switch I might have shorted something but with a good PSU like I have on a protected circuit it shouldn t happen I saw an existing post were someone had the same problem and had used the PSU switch But it is design to do that Not fry everything by using it The Antec PSU also has a protection against surges Tonight I will try to use a W Enermax PSU I have in another computer and see if it changes something If not than they are possible solution Maybe just the buttons but I doubt it or the Motherboard is screwed If it is the motherboard and my Waranty is not good anymore I will have to buy a new motherboard and a New CPU reinstall Windows and my Video Card which is AGP won t work in a PCIE MOBO So I will have to buy a lesser MOBO and if future upgrade have to come I won t be able to buy a PCIE Video Card If they still do the AGP by then By they way they still sell Athlon XP MOBO in my local computer shop but they are so cheap they don t have AGP X or DDR So what do you think it might be Any suggestion as to what I may Try Anyone with a similar problem AMD Athlon XP Gigabytes G A- L Motherboard nForce X MB of DDR Memory in Dual Channel Antec W SmartPower Maxtor GB MB IDE HardDrive Primary Master Pionner DVD- D New DVD Burner Secondary Master Geforce GT AGP w Additional Power plugged in Creative Live Soundcard ComproPVR Video Capture C...

A:Computer won't start anymore after closing it with Power Supply Switch

Hello and welcome to Techspot.

If after trying your other psu it`s still dead, It`s got to be either the mobo or cpu.

I think for whatever reason, you`ve had a short circuit of some kind and it`s fried either the psu/mobo/cpu.

You`ve seem to have tried all the right things, so I can`t really suggest anything else.

Regards Howard :wave: :wave:

A:Computer shut down - power supply problems? - fans start/shot off - not booting

Depends entirely on what the issue is. If the PSU is supplying power but not stably and the board isn't powering up because of that, you could be looking at just a PSU replacement, or various components.

What type of processor do you have? If it is an older model Athlon and the fan was not spinning fast enough, in theory it could have overheated and fried, though that is a rare occurence unless the fan outright stops spinning.

So I turn my computer off one day only to find it wont start the next day. I open the case up and see the led is on. I flip the switch on the power supply off then on and quickly press the power button. My computer starts but the following time I shut down the computer it again wont start and now the led is blinking. I've never had any issues like this before, any help would be appreciated.

I don't routinely use many usb devices, only my mouse and keyboard and every now and then my ipod. I figure the issue is likely either the power supply or the motherboard. The ps is almost two years old while the motherboard is only about three months old.
 

A:Computer wont start, power supply wont start, blinking led

It sounds to me like your PSU is the problem, get a hold of another and plug it to your computer and see if that will make it start, if it doesn't it might be BOTH your motherboard and PSU. A bad PSU will burn a motherboard.

Hello,

My Satallite R830 won't turn on.

The power symbol flashes orange 8 times then pauses and restarts. there are 6 quick flashes followed by a longer one on the 7th flash then another quick one. The wireless symbol is lit up (orange) all the time.

If I unplug the laptop and take out the battery and hold the restart button for 30s then without the battery plug in the charger the flashing stops and the power symbol goes green, until I try turning it on, it has a split second where it sounds like it's booting up then stops and the orange flashing resumes.

Same thing happens if I unplug the ac adaptor and the battery and then tried the above but with the battery and no ac charger.

I have tried with another adaptor (same amp and volt output).

Can anyone help?

Many thanks

A:Satellite R830 won't power up - flashing power indicator

>6 quick flashes followed by a longer one on the 7th flash then another quick one

If the power supply microcontroller detected an error the DC IN lamp sends a blinking code.
The short means 0 and long means 1.
I your case this means: 0000 0010

Since error code starts with LSB (least significant bit) you have to read it from behind
0000 0010 -> 0100 0000 -> 40 H (hex)
Now you will need to know what 40 H means

According to some details which I found in internet, the 40H could be the S3V output fault. (S3V voltage is over 3.47V)

However, such errors are mostly related to motherboard problem (internal circuit problem) and from my point of few only part replacement would fix this error.

Toshiba Satellite L305-5955, Ive taken apart and replaced power jack. Not directly soldered to motherboard. While still apart, and battery out/in, connected power supply and still absolutely no response. Power supply is NOT original, and slightly different specs, i.e original 19v..6.3A

current 19v..3.1A
 

A:Toshiba Satellite L305-5955 does not respond to power supply, new power jack

Almost certainly the problem is that the current rating is wrong, if the laptop needs
6.3 A of current, it won't function on less (just as you can't use a 3A fuse for a kettle!)
Unfortunately it must be the right current rating, I know, I've been caught that way too!
Maybe you can exchange it?

Hi,
I picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.
 

A:No power, no lights but green light on power supply blinks rapidly

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

I have a Dell 8600 about two years old. When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so. I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally. Any ideas?

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

The motherboard has a power connector for the graphic card next to the slot.

Is there any reason I should connect the power for the card to the power connector on the board instead of directly to the power supply?

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.
 

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place. My warranty with best buy has expired, so I need to figure out how to solve this problem on my own. I can't just leave it like this because the cord comes out really easily and I can't continue to work with such a tenuous setup. Anyway, is this just a matter of replacing the entire unit inside my laptop? I know you probably need more information, but I'm not sure what to provide, so please ask any questions. The laptop is a Toshia M-45, about 3-4 years old. Thanks in advance

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

You have pretty much the same problem as me (getting BSOD's randomly). For me it's bulging capacitors on motherboard. You should take a closer look for capacitors on your motherboard. Dead capacitors look something like that:

Yea...so we finally got my girlfriends new PC up and running. The problem im having...or more of a concern really. Is when you flip off the power supply, and then flip it back on, the PC gets a short burst of power. IE the lights and fans all come on for a second or two. Then you can press the power button and turn it back on.

Any ideas guys?

I shut down my Pavilion Elite for 1 week while away and now it will not turn on. The power supply light is on, I replaced the CMOS battery and the power switch is ok.

A:Pavilion elite power supply light on, won't power up

As you did not mention any message or display on the screen, I would use this tutorial for a step by step diagnostic.  It also helps to remove the side panel, and visually watch the CPU and rear case fan movement(s).  As you press the power button, pay attention to the fans. Also does the Power Supply LED stay ON? Or did it go OUT when you pressed the power button?

A:Computer won't power up after disconnecting power supply

While installing the new optical drive, you might have inadvertently loosened one or more connectors. Recheck all data and power cables to make sure they are tight, including all those to the motherboard.

A:Power Supply Question & HD Power Consumption

Power Supply Question & HD Power Consumption, Pt. 2 - Laptop vs. 3.5"

My second question is this - I have a BTV server that needs to be on at all times during the season to record shows during day and evening.

Suffice it to say that you CANNOT reliably put one of the critters into sleep/hibernate mode and expect it to wake up and reliably record a show. It just won't happen.

Now, this is one case where I can use "Green" 3.5" drives, but I am also considering banking 500GB 7200RPM or even 5400RPM laptop drives. These will all be on a raid controller, but since they will be in pass-thru mode or RAID 0 mode the controller won't freak over TLER like it would with RAID 5/6 and mark the drives bad. The controller also has more than adequate cache to handle a 5400RPM spindle as OTA HDTV generates little more than 2.5MB per second per channel. Even 4 channels at once is 10MB/s and that should not tap the ability of a 3Ware controller with cache on 5400 RPM RAID 0 or even pass-thru drives.

My question is this - 2 500GB laptop drives burn much less startup and idle current than a single 1TB 3.5" drive. Has anyone tried running multiple laptop drives on a RAID controller, and what sort of luck have you had? What sort of sustained throuput can you obtain?

Electricity is a huge factor here, at 12 cents per KWh. I can recover the marginal cost of 2 500GB laptop drives vs. 1 1TB 3.5 drive.

Case construction and drive cages are not the issue here.

Ok so lately I have been getting a BSOD at very random times and it looks like a Diver Power State failure. SO all of my friends and every website I go to makes it seem like I need to get a PSU. Right now I have a Quad Core and a 8800GT and 375W PSU. So my friend told me to get a new 700W PSU.

So, if the only fix is to get a new PSU? I tried to rollback my GPU driver but it didn't help.

So any ideas?
 

A:Driver Power Failure = New Power Supply?

You're greatly risking the health of your whole computer while running with such underpowered power supply. Do yourself a favour and get a quality PSU. http://www.newegg.com/Product/Product.aspx?Item=N82E16817341010 That's the cheapest one that is enough and of good quality that I could find with a quickish search.

A:New power supply, no schematic, looking for power fan plug.

There are basically two voltages available to you: 5V and 12V. Doesn't really matter where you get it from - some pin on the mobo or some wire from the PSU.

From the PSU the yellow wires are 12V and red ones 5V, black is ground. The fan voltages should be written on the fan itself, the black fan wire is ground, red may be 12V or 5V depending on the fan voltage.

Fan headers on the motherboard should be labelled so, check with a voltmeter what pin gives out what.

A:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

I have a generic MB (P-120 CPU ) which I just switched to a different case and power supply. It has an extra "six pin power type connection" in the middle of the board. Only one supply that I have matchs this and the wires are three green and three black. What is the funtion of this connector, it looks from the wire colors to be some form of switch.

Its a case of not wanting to swap out the power suppy from my other unit unless necessary. I have 4 other supplies and none have the extra wire, which is listed as P10.

Many thanks in advance.

Does it happen with any other appliances? as in does using the toaster while using the kettle While your mate is in the Electric shower, telly on, or ironing?

Possibly a static build up, it is possible, Wher are you situated??
What voltage are you on?

What is the make and model of your comp? is it the same as your friends?

is your machine custom built or is it a brand?
Answer a few of them and we will try to narrow it down 4 you..

Mean while if you could get your hands on a spare PSU that would be handy. And remember when dealing with PSU's alway leave them to sischarge for at least 24hrs,

Hey, got quite a problem with my laptop.. It's a Medion Erazer X7813, worked well for ~2 years.
I was doing a graphics card benchmark yesterday and it stopped in the middle of it(monitored temperature, it was at ~80 degrees Celsius when it turned off). No bluescreen or anything just off and I couldnt restart after that(no fans nothing). I thought it might be the power supply, so I tested it, but it was doing 19v when not plugged in, but when I plugged it in and unplugged it again it was at 1v. When testing I unintentionally shorted the power supply and it showed 1v after that just as it did after plugging it in, is it shorting inside the laptop? Could it be the battery or something more serious like the MB? Any ideas are welcome!

The computer runs for about 2-3 minutes and the Poff! screen black, Power led flashing slowly. I have stripped out everything except memory, started and gone into the bios and left it there just monitoring the board (voltage and fan speed). Same thing happens. My dilemma is to decide if it is the motherboard or the power supply. It is not memory, I have 2 banks and have tested one and one. I am currently in Gran Canaria, Las Palmas so its a bit difficult to find hardware. Any help on how to decide?

Check your power management settings (and reinstall software if needed, from the manufacturer website). I've run across many problems with SP2 messing with power management settings...

A:installed new power supply...still no power!?

Is the LED lit on the MB? Try bypassing the front case switch by putting the blade of a small screwdriver across the pins on the MB that the switch connects to.

Came home walked in and noticed my PC was off monitor was on speakers on modem everything on as if the power had blinked out for a sec and my system had shutdown No Supply, lights no to Power power I pressed the power button on the front and got nothing i checked the power supply s own power on off switch on the back and got nothing no light that its on or anything thought maybe it was the cable so i plugged it into my other pc and the No power to Power Supply, no lights cable No power to Power Supply, no lights works so i m thinking maybe the psu went bad or took a hit Im guessing i just need to replace it How difficult is it to replace it by yourself i ve never done that before and do you think that its the psu at fault I m thinking that if there is not power on light then something is wrong big with it my heat temps stay down between C and C at the highest Also can i replace it with just any other w power supply or does it need to be a specific kind company i bought it from online listed it as dual core certified w psu no mention of v rail or anything else i guess i can get that from them if they have it on file nbsp

A:No power to Power Supply, no lights

Well sounds like your power supply took a power surge. Well to start with i would try a power supply. Now about replacing the power supply cheap is not the best way to go, learned from experience. Here is my recommendation: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005
And for replacing a PSU not hard. If you need help removing it Post back i will walk you through step by step if need be.

Ok so i do know what the no Power and supply 100%, mobo are power problem is this is more about what i can do to use my computer until i can fix the problem Ill start off with what the problem is My computer wont turn on from the get go i knew the power supply was okay Power supply and mobo are 100%, no power because the mother board has a green light on it showing that its getting power of course just in case i tried putting a new supply in but there were no changes At first glance the mother board looked good No blown resistors or anything of that sort i sent it to a friend to check it out though once again just to be thorough and sure Finally after Power supply and mobo are 100%, no power hours of tedious searching i found the problem The chip that the power button plugs into has blown out Very happy thats all it is Now my question to all of you is is there anyway to bypass using that board so i can run my computer until i replace it if i just unplug the little board that the button is a part of the computer obviously does not turn on when i attach the computer to power and i dont know how i can trick it into turning on without having the use of the power button Any info would be greatly appreciated Thanks Ryan nbsp

A:Power supply and mobo are 100%, no power

There are some motherboards that have a power on button directly on the motherboard. I don't suppose you have one of those? There are some BIOS' that can enable the keyboard to power on the PC by pressing any key. I'm using one of them now. Of course, the problem with that is to get the PC started in the first place so you can change the BIOS setting (if it has that setting).

What motherboard do you have?

My PC suddenly shut off and wouldn't turn on, but the mouse and motherboard lights were still on. A tech took my PC and ran some tests. I assumed that either my Power supply or my Motherboard was unfunctional but he called me back telling me that it was neither, and that the problem was coming from "a part" that gave power to the motherboard. The replacement of this part would cost $80.

Am I getting ripped off? What part could possibly cost $80 and isn't the Power supply?

Background: I am running MS Office 2003 on WinXP 2002 SP 2. I tend to have all of the MS Office Applications open at once plus AutoCad and Lotus notes. I have 2GB of ram.

I have a PPT file open when the screen starts flashing, I cannot page forward or backward, or edit the slide. I CAN go to slide show or quit, but if I restart power point or end the slide show the flashing starts again. I CAN go to other application and they seem to work normal.

ANyone have any idea what's going on? I seems to me it may be some type of power point memory problem.

Thanks

I have a 3-4 year old Compaq Presario SR2017CL desktop and recently (maybe a month or so ago) the power-on button (green) began flashing when the computer goes into hibernation. I saw this a year or so ago and there was usually an update to Adobe, Microsoft, iTunes, etc. that needed installing. I've checked all those and can't find anything to explain the infernal blinking! I even downloaded an update to the BIOS and that didn't do any good, either. Can you think of any reason for the light to blink? It's actually the lighted power on button and not an indicator inside the box. Other recent changes I've made to the system: removed Norton Antivirus using the registry since there was no uninstall for the program (also a puzzle to me????) and uninstalled my Kodak printer for reasons I won't go into right now. Would appreciate and help you can give.

I bought my XPS a couple weeks ago and immediately upgraded the memory to GB Everything worked fine but I then decided to upgrade the video card to an EVGA GeForce GTX SSC This card requires both a and an pin power connector which the stock Dell PSU doesn t provide So rather than return the video card I upgraded the PSU to a Corsair CX M which I ve read other XPS users have had success with in this machine As others have reported this PSU is a tight fit but I was able to get it installed As soon as I powered it on my problems began The case and CPU fans spin I can hear the HDD spinning up and I can open and close the dvd tray So I know the PSU is at least providing some power But I get no video and the power indicator on the top of the case flashes an amber pattern I ve tried reverting back to the stock dell PSU and video card but still have the exact same issue nbsp I ve 8900 Light Flashing XPS Power also tried unplugging the power cable and holding the power button for sec But still the power light flashes the amber pattern I know there are no beep codes for the XPS and that the power light s amber flash pattern is used instead to diagnose the issue but I haven t been able to locate any reference to what the patterns indicate The power indicator flashes a - pattern and repeats Does anyone know what this means

A:XPS 8900 Flashing Power Light

Followup:
I had ripped everything out with no luck. Well, everything except the upgraded memory. It had been working, so I didn't think it would be necessary to remove it. But I was wrong.
I reverted back to the stock memory and the blinking amber light problem went away!
Then I re-installed the new memory, and it also worked!
So I guess it was just that the memory needed to be re-seated.
Not sure if the 2 - 7 pattern means "Memory issue", but that would be my guess.
Since the XPS 8900 doesn't support beep codes, I hope Dell will eventually publish what the flashing light patterns mean.

I have an HP Pavilion M70 monitor.
My power light keeps flashing and there's a clicking
sound (sounds like a relay clicking). Pressing the power
button or any other button does nothing.
HELP!!!
 

A:Power light on HP Pavilion M70 keeps flashing

Sounds like a power supply shutdown. It happens when there is a major component failure which causes the power supply to keep resetting and trying again (the "clicking" you hear)

Needs servicing or scrapping.
Monitors are usually not often worth fixing these days, unless it is very minor (and that does not sound minor)

A:Solved: Constantly flashing power LED

As it turns out, it signals a hardware issue on the inside and through further testing I discovered that my CPU fan was failing to activate upon booting the system up, thus the CPU was reaching its maximum temperature and automatically shutting down to prevent damage.
