Power supply died, now monitor will not power on

Q: Power supply died, now monitor will not power on

My power supply died a few days ago and I have replaced it. My PC will now boot but will not send a signal (turn on) the monitor. Everything on the PC seems to work but it just will not turn on signal to the monitor. I have tried two different monitors with the same result.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Presently have this power supply:

Antec BP500U ATX 12V 500W Power Supply

Computer overheats and shuts down. On checking, the fan in the power supply stopped working. Looking to replace the power supply with a different brand. The fan in this one was LOUD.

I'm running an Intel Core i7.

Does it matter what brand/type I replace the power supply with? (I see 550w, 600w, dual power. Should I consider any of these?)

Are there any recommended brands/models that keep it very cool and very quiet?

Hi all,

my power supply died two days ago. By chance, everything else seems in
order, except for the USB ports which act strangely.

I bought a new power supply and installed it. The computer boots normally
and the OS starts without a problem when there is no USB devices plugged to
the motherboard.

If I try to plug something to the USB ports while the computer is on, there
is no problem and all my USB devices work fine.

But if I boot with the USB devices plugged to the motherboard, the computer
doesn't even try to boot (nothing happens when I press the power button).

Someone have a hint?

If the USB ports are not working properly, should I change the motherboard (in case it blows up something else with time) or just disable USB ports and buy a PCI USB card?

Hi, this is my first post, so I hope I can explain what happened to my pc clearly. I have an older gateway 450mhz and recently I tried to power it up and nothing happened, like it didn't have power. So I reset my power strip thinking it just tripped the breaker, and it started to come on, I could hear it power up and then it just shut off again, no power, lights or any thing. so I plugged it directly into the wall. and the same thing happened, started to power up, and it was like it would reach a certain power level and trip some kind of internal breaker or something.
Hopefully there's someone out there that knows whats wrong and if its worth fixing..... Thanks alot for any replys

I have a Lenovo Thinkcenter i7 M92 that worked a while ago and when I turned around to work on another computer, it apparently turned off and now the power will not come back on. The power button wont even light up, nor will the lights where the network cable plugs in. Have tried different outlets, different power cords. I am thinking it is a power supply issue but I cannot find a power supply to order. Any suggestions would be greatly appreciated.

Hi. This is the story. In the middle of my son using the computer, it just shut down. I came down to the room where it was a minute later, tried flipping the master switch on the surge protector off and on, then pressed to power button on the case. It started up. A few minutes later my son called me again because it had shut down again. The former trick didn't work. Here's what I've tried:

Flipping the I/O switch on the power supply both ways and trying to power up.
Unplugging the power supply from the surge protector and plugging it with another cord directly into the wall outlet. Then flipping that I/O switch again.

Nothing happened. Does this sound like it's the power supply?

A:Computer died!! Is this a power supply problem?

I`m afraid it does sound like the psu has gone bad.

However, the only way to tell for sure, is to try another psu, and hope that`s all it is.

2 days ago the power outlet that my computer was placed into was kinda half exploding. And the "lightning protector" that was attached into it died. I was trying to connect the computer to a different power outlet , and the computer won't turn on.
Not sure what happend... So Idk what to do... Should I buy a new power supply and see if everything is ok? Or just give the computer to some lab and have em to "make it work" ??

I am sure that you can located one in China for fairly cheep, especially since they are probably made there anyway, and then upon your return, have the original replaced under warranty.     Ask around, there must be a computer outlet somewhere that sells parts that can locate one for you in China.    It may be a knockoff, but it will get you by for your trip, just make sure the voltage/amperage match that printed on the original.

Right now I'm running (2) 24" monitors on the 300W power supply that came with my computer, which apparently is super weak but works fine. I'm going to add a third 24" monitor to my setup so I'm going to need to add a second video card as well, as I can only run two monitors off the card I have now. So with 2 video cards running I'll probably need a better power supply, but unfortunately I know next to nothing about them. I should note I already know what video card I'm going to get, that's not the issue. If a new power supply will do I'd much rather get a new power supply + new video card than one of those matrox triple head adapters or whatever they're called. Any suggestions?

A:Monitor Causes Power Supply to Buzz

Some CRTs degauss themselves every time they turn on. So yes, it is probably the degaussing circuits inducing or emitting some noise.

See if you get the buzz with the DVI cable unplugged. If it still buzzes, then the cause is EM radiation and it's nothing to worry about.

A:No image on monitor after new power supply

You say the board beeps once. One short beep I think would indicate a DRAM (or more likely its controller) malfunction. You could possibly try to start the system with one RAM stick and try successive memory slots, then alternate with the second stick, but if the board is emitting one short beep then the prognosis is not good.
One long beep would indicate a successful POST (i.e. a normal system start)

I am starting to think I may have a power supply issue and none of the programs I use seem to monitor it correctly or the power supply is bad. I have been using TOverclocker (came with my Biostar MB), Speccy, Everest, HWinfo64, HWinfo32 and SpeedFan. None of these give me consistent measurements or measure the voltages wrong from opening the program. Is there a monitor program out there that is very good at measuring power supply voltages. My MB is a Biostar TZ68A+. Thanks in advance for the help.

A:Program to monitor Power Supply

What symptoms are you having that you think may be related to a PSU issue?

The best way to measure voltages is not with a software program, but rather with a digital multimeter (set to DC volts on the 20V range or automatic) and using a technique called backprobing whereby the probes are inserted into the back of the power connectors so that they make contact with the wires inside. The only software that I would trust on voltage readings is the hardware monitoring in the BIOS (and even then I would take the digital multimeter reading as being the definitive). This is because software that provides this function takes its readings from the on-board sensors and then applies a predetermined offset which gives you the final output reading. Unfortunately, if the incorrect offset is used, it can lead to cases where a voltage is displayed as being out of tolerance whereas the same voltage tested directly is well within the limits.

Certainly, don't stop using these programs if you wish, but remember that the readings that they give should be treated as a guide and that if you have any undue concerns about any of the readings you should confirm (or otherwise) them with a digital multimeter as described above.

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!

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.

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.

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.

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.

It's been a while since I built a system from scratch and have a... errr... simple question

gfx: Sapphire HD3850 512MB Ultimate (passive)

MB: MSI P35 Neo2 FIR

PSU: Seasonic M12II 500W

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?

A:Graphic card power to power supply or connector on motherboard?

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.

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

Hello guys.  Can anyone help me understand the power supply on the HP Envy Phoenix 860-019?  The PCIE connector 6 pin connected to the GTX 960 has black and white wires.  Shouldn't there be yellow and black wires?  Yellow is usually 12 volt and black wires ground.  Is the 6 pin connected to my GTX 960  supplying a standard 75 watts of power or something else?  I want to install a GTX 1070 but the 6 pin wire colors are not the industry standard color scheme.  Also there is a 2 pin power connector with a white and black wire.  Usually a 6 pin and a 2 pin can be used together to connect into a 8 pin socket on a GTX 1070.  Will my connectors supply the needed power and connect properly because the color scheme on the wires make no sense. Thank you

This happens:

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

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?
Relevancy 84.28% 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?

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!

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.

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.

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.

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?

hey I have an interesting problem supply jumper power and power When I plug the atx power supply into my motherboard as soon as it makes contact the psu fan spins about times then power supply and power jumper stops which i suspect means its testing to see if it works or something But i have a computer out of the case and i power supply and power jumper might have made the fatal mistake of useing a paper clip to quot jump start quot the motherboard by contacting the power jumpers now whenever and metal contact is made paper clip the actual start mechanism anything it won t cut on Well me thinking i must have messed up the jumpers cut the psu green and red cord i double checked to make sure they were the power on cords and twisted them togeather and put electrical tape around them I know its not the best job but i was just testing a theory When I plug in the psu and its plugged into the motherboard the psu fan becomes turned on because of the twisted on wires and spins But the cpu fan and motherboard remain powerless I am wondering if i ve done something wrong or have screwed something up any help would be appreciated ps before the problems begain i installed the motherboard into a case because it was just components and i founnd a cheap case When I installed the motherboard I screwed metal screws into the contace points where the motherboard is supposed to rest I heard somewhere metal is bad for the bottoms of motherboards so that could be it thanks nbsp

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

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:
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.

A:Would a 500W power supply power this

Hi QGamez,

I reckon a 500W wouldn't be enough but a 750W may be the right one. I had a look in a few forums and they had 650W & 750W etc but not 500W.

But wait for more input from the others and see what they have to say

1) I need to know the pin-outs of the connectors (1-4pin, 1-14pin, 1-5pin on ribbon wire), specifically which ones control start-up and various voltage outputs.

2) Being a Switching Power Supply, I think there must be a load on at least one of the output rails. Can I create this with a simple resistor of some sort? if so, how exactly what would I need to do.

I can email photo of the connectors if that would halp. I would appreciate any help. Thanks.

A:Power Supply - "The AC power adapter type cannot be determined....."

You are correct, the failure is due toloss of the power supply ID signal. Sometimes this happens because of strain on the plug, which breaks the signal wire. Some even are so severe that the insulation breaks away from the plug; this is due to rough handling. The other cause is one or more of the power socket solder connections to the system board become broken. This also is related to severe handling. I have seen one case where all three power connections and three of four mechanical connections were disconnected. If the power supply is bad, a replacement will cure the problem. If not, then the socket is bad, and this will require a system board replacement. If you are experienced, you can try to resolder the connections. I am experienced and was not able to get my daughter's E6000 to work by resoldered. More recent Dells are using a replacable power connection board which is a much cheaper repair.

Hi all,

was in the process of installing 8.1 on my home pc when the power shut off in my house. Of course this would happen. I upgraded from Vista using the digital upgrade thing early last year, and since I have no physical cd/flash drive available, is it possible to reinstall windows 8 prior to the loading screen?

When i try to start it up it and get an error with bad_system_config_info so something got corrupt when my power went out. It goes through trying to repair it then suggests I system restore however it just gets stuck at the w8 loading screen for 20 minutes now. I don't have anything on the pc i can't do without, i Just want to reinstall it/boot into a safe mode so I could reinstall windows that way.

What are my options here?

My son was playing a game on our Dell XPS 2720 when all of a sudden the computer just died.  Now when we press the power button, the power button does not light up and it sounds like the only thing that turns on is the fan for the power supply.  There is a small green light at the back of the computer underneath where the power cord is plugged in that is lit.  Otherwise, there is no other indication of life.  I have tried unplugging the machine and holding down the power button for 15 seconds, but that does nothing.
Anyone have any suggestions of what to try next?

A:Dell XPS 2720 died and will not power on

Unplug the system and hold the power button for 30 sec.  Remove the back cover and the memory modules -- then reinstall them, button the system back up and try powering up.  If that brings it back to life, you're set.  If it doesn't, it's a bad mainboard - unfortunately, this is essentially a notebook system on a stand, so the board is proprietary and you'll face a $350-550 charge for a replacement board (plus labor).

After googling this issue, I am seeing this is a common issue and Dell does not have an answer for it. other than replacing the motherboard.

any suggestions would help especially since this is financed threw Dell still.

My HP desktop had been shutting down after being on for about 3 hours. I could power it back on after resetting the power cord. I ran tests on sys board , processor and hdrive which were fine. Then it shut down again and I smelled a burning smell and I heard a sizzle (that could've been the speakers, which have a short.) I opened the case and found that the heatsink on a SiS chip had fallen off. I don't see anything burnt. Also a while back, I noticed the switch on the PSU was set in between 115w and 230w, so I switched it on 115. What do y'all think caused it to shut down?

A:Is it the power supply?


Ok you ran TESTS? please explain:
And they Fell Off the SiS chip, you mean CPU Chip i presume?
You man not see any signs of damage, your system may shut down to prevent damage but if the system had been active and accumulated heat prior to the heatsink falling off there may have been little time for this to prevent itself from melting.

Sounds like a PSU gone too, Mine did that bout 3 months ago... What Wattage and Amperage was the PSU, Also Post your Spec, as i may be able to make a reference for purchase of a new one...

Did you modify your System in any way?

Just bought a barebones AMD Athlon 950. Am going to put all my old computer junk in it that is collecting dust, might as well do something with it all:

3GB master HD
1.3GB slave HD
24x Internal Phillips CD-ROM
Phillips 4x External USB CDRW
3.5 Floppy
32MB AGP Nvidia GeForce2
Creative Labs Audio PCI 128 Digital Sound Card

My question is, would a 200W power supply be okay for this system? The board originally came with a 250W power supply. The 200W is a power supply out of my old PII 333Mhz system.
