Computer won't power up (poss. power supply)

Q: Computer won't power up (poss. power supply)

Hi I m currently a computing student so I rely won't up power (poss. Computer supply) power on my computer a lot for my studies and was hoping I could get some quick advice troubleshooting on here So here goes I ve had a problem with my computer recently it s been working fine Computer won't power up (poss. power supply) for a year or so with no problems and then one day i tried switching it on and nothing happened I tried once more and then the power short circuited I then had to turn the power back on from the mains switch The strange thing is my housemate had exactly the same problem and after searching for the answer he was told it was due to a static buildup and the solution was to take out components graphics card RAM e t c and put them back in I tried this and no luck I was thinking due to the short circuit there may be a problem with a fuse in the power supply other then that I m completely stumped and would appreciate any help given Many Thanks for all help received nbsp

Preferred Solution: Computer won't power up (poss. power supply)

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.)

A: Computer won't power up (poss. power supply)

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,
the 3 D'S, Disconect, discharge, dismantle.

My first post I received my new DVD DL -RW drive today and eagerly installed it I of course unplugged my computer s power supply while doing it After plugging the power back in the green up power disconnecting after power supply Computer won't LED on the back of the CPU started blinking never noticed this before and when I hit the power button NOTHING happen No fan Computer won't power up after disconnecting power supply turns no lights nothing When I unplug the power supply the green LED blinking gets slower and slower and after about minutes it totally stops I plug the power suppply back in and it starts blinking all over again and still the power won t turn on All I did was replace a CD-ROM drive with a DVD Multi drive I didn t mess with anything else so there should be no power supply shortage or problem Any thoughts as to what could Computer won't power up after disconnecting power supply be happening By the way I have a year old Compaq computer with ghz Athlon gig RAM no problems thus far nbsp

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.

I have a Delta DPS-150GB B Power Supply out of an Apple Macintosh Power Mac computer. I would like to use it as a 12v/5A power supply for my model train layout. I have a couple important questions:

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.

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?

A:Power Supply Wont Power up - Gigabyte ga-ma790fx & AMD Phenom 9850

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.

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?

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

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

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

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.

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.

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?

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.

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.

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.

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.

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.

A:extra power leads on power supply?

Sounds like typical extra +5V lead and can be used for any number of things...(riser cards,backplanes,to drive extra slots, etc.)

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!

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?

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. That's the cheapest one that is enough and of good quality that I could find with a quickish search.

Why would you want to use a desktop power supply to attempt to power a laptop? Completely different applications and even though you would be using 12v DC you could still damage the laptop...or worse. The power good line is for the power supply to receive a signal from the motherboard that it is getting all the power signals.

That's an absolutely horrendous PSU, return it and get a decent Antec/Corsair/XFX unit. It should tell you something that a PSU apparently rated at 650W only has one PCI-E connector, I.e. it's bad quality and won't output anywhere near 650W.

Hi I need to know in short how the computer power supply works My concern is based on the s Ac powered wall clocks would vary in their accuracy due to the cycle rate from the power company not being dead on the cycle scheme They usualy were a bit higher power question supply computer I understand all that Today the Hz cycle rate from the power company is still a bit high fast With that in mind I m computer power supply question getting to the question computer power supply question With the power supplys used today in computers is it possible due to the AC input cycle flucuation for the computer clock to be running slightly fast It was argued that the comp clock shouldn t be running fast A search on the internet will show that this is a common occurance I just figured that it may be from the AC input source that could cause the timing to flucuate and hence cause the system clock to also flucuate While not harming anything within the comp with it s daily functions it could however have an effect on the system clock and it s accuracy I ask this due to me getting into the field of watch collecting Most movements being Swiss mechanical In checking for accuracy of the movement I ve discovered that I d have to use some sort of Atomic Time refferance via the internet because my system clock consistantly runs about secs fast daily hrs This is where the argument came in It seems some judge their movement accuracy via their system clock I mentioned that that wasn t a good idea because the system clock may not be accurate This inturn opened a whole can of worms It was argued that the system clock should be accurate because of the fine tuned input from the power supply shouldn t allow any flucuation from the AC power source Now you ve got the idea of the question and why Thanks for any help in advance nbsp

Unfortunately I had to pull the plug to get it to shut down( I know don't say it!) Well that was it. It will not start. it will not do anything it is just dead. I check the electricity and the plug to which the computer was plugged in to is good. The light I use to check it with lit up.

I even tried a different plug different wall....still nothing.

So I am guess the power supply may have gone out.

I have a homemade system that just died. It has a Duron 900 that I know had been running hot (175 F). It also has a 375w power supply that also serves as a power strip. I removed the heat sink & fan to do some cleaning (spray air to knock off dust on the MOBO around the CPU). I broke one of the prongs on the socket that holds down the heat sink. A "friend" suggested using super glue to re-attach the heat sink. Now...nothing. The reset button lights up on the power supply, but the fan does not kick on and nothing else functions. Would a dead CPU cause this...power supply...MOBO...or a combination? Thanks for your consideration.

A:dead computer - CPU or power supply?

CPU sounds fried. Superglue? Really? I'd replace both the cpu and the board as you can no longer attach a heatsink to the board unless you have mounting holes and can find one that attaches with mounting holes.

You should look up the ATX pinout and dimensions on the internet and compare with your PSU.

its either power supply or heat related. you can buy an inexpensive power supply tester for about 20 dollars at different sites... that will tell you if that is the culprit. If that is not it I would say its too much heat as that will cause freezing at intermittent times. You can download temp monitor programs and monitor your southbridge and cpu temps to know if thats your problem.

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?

Your first and biggest mistake was to "keep turning it on and off".....A big newbie mistake!!!!

What you should have done is; when this first happened is, shut it down and do some research on this "Asus Anti Surge Protection" error message. Which I did and come to find out that this Asus software is buggy to say the least.

So now you're at a precipice. My thinking is that you may have done some real irrevocable damage to the mobo/cpu/psu or the entire system. The only way to know for sure is to swap out parts with known good working parts. Start with the PSU first.

I really don't have much experience with computer hardware, the only thing I've done previously was add two sticks of RAM.

Well, I ordered a graphics card and power supply for Christmas. They just arrived, (1 1/2 weeks late thanks to UPS) so I opened up my computer, removed the previous graphics card and power supply, and put the new ones in. Well, I closed up the case again, and whataya know, the computer doesn't start up. (Absolutely nothing, just sits there like it was unplugged) The funny thing is, theres a small green LED displaying on the mobo when I turn on the power supply, which I figure means it has power, so it should be doing something.

A:Upgraded power supply, computer not booting up

The led on the motherboard only means there is some power supplied to the board. It does NOT mean you power supply is working correctly.

Here is what I would do.
1 Go back and recheck ALL of your connections. Make sure you have installed the 4 or 8 pin aux power connector.
2 If after rechecking all connections and it still does not work, then reinstall your old power supply and see if the system will at least post. This way you can tell if it is the power supply or perhaps you have damaged something while working in the case.

When you removed your old video card, did you uninstall the driver before shutting down and pulling the card?

Here is the proper way to upgrade your video card.
1 Uninstall any software that is used by the old card. This includes driver, any type of control panel, etc.

I had posted last week about my CPU which would power down and turn off then back on for a second or two then off again over and over Now it won t even turn on I took the power supply out and had a geek guy at best buy check it and he said the this supply?) off GOOD for Computer time(power voltage coming off of the power wires for the drives was at or so volts when it should be at When he hotwired it the fan at least came on which was more than I got But he said he s not entirely sure it s the power supply and not the motherboard If the voltage is wrong then i would think for sure it s the supply The other thing is a little green light on the motherboard comes on when it s plugged in but that might still operate with the low voltage I wanted to get a new supply tonight if this is what it is My comp is a Dell Dimension and the power supply that best buy carried looked to be the same size Computer off for GOOD this time(power supply?) with the screw holes in a similar configuration even though this same dude said Dell sometimes needs a specific supply that matches a Dell because of size and layout issues Should I just drop the and get one or could it possibly be something else that is going wrong nbsp

Hey guys A few months ago i supply maybe? turn on won't properly. Power Computer upgraded my PC by getting another HD had R x and running crossfire I also had Computer won't turn on properly. Power supply maybe? to upgrade my power supply to support both the cards and i managed to find a really good deal on a PSU a Seasonic X-series SS- XM Active PFC F I can't quite remember but Computer won't turn on properly. Power supply maybe? it was around that time that i thought my power button on my case had stopped working when the computer is off although it will still shutdown the computer if it is on I assumed it was because of my motherboard being so small and the second graphics card pushing on where the case power button is plugged in Since then i have just been leaving my computer on But when i do have to turn it on i have to slowly flick the power switch on the PSU on and off which after a few or many tries would turn on the computer Today i finally went to troubleshoot what was wrong so i could buy a bigger motherboard or whatever and found it wasn't the power button on the case Removing the second GPU so the power button can be plugged in properly didn't change anything and the power reset buttons on the actual motherboard also do not work I'm assuming now that it is the power supply but i'm not too sure as i know the motherboard is still getting power when the computer is off the Ethernet port lights up and when the computer is on there are no problems are all I can play very demanding games for hours straight and leave the PC on for over a week without it ever turning off Another thing that might be important is when i put the computer into sleep mode overnight it will at some point during the night turn itself off completely Here are the specs of the PC and if you need any more information just ask http i imgur com mPAC O png

A:computer won't boot up after installing new power supply

There is a very simple test for the power button on the front of the case. You can switch the wire leads from the reset button. To do this follow these directions. Note before doing the following, do make some note as to how your case leads are connected.
1 Locate the case leads and where they connect to your board.
2 Remove both the reset and pw switch leads
3 Now connect the reset lead to your pw switch pins on the board
4 Press the reset button and see if it turns on normally. If it does, you simply have a failed pw switch on the case. If it does the same thing, then you know it is either the board that has failed OR the pw supply is defective.

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.

Hi all

This isnt an ongoing problem but since ive bought my computer at launch, every month or so, it will randomly switch off, and wont switch back on until ive unplugged the power supply for a couple of minutes then plugged it back in, then it will switch back on and work fine.

Is my power supply failing me? or is it being overloaded or is it another problem

A:Computer Sometimes Switches Off Randomly, Power Supply?

Chances are it is your power supply if it is turning itself off like that, try using a different kettle lead. If that doesn't work, I would replace the power supply unit, it shouldn't be that expensive. Are you getting any error codes before or after the system failure?

EDIT: Saying that, I have seen problems like this before simply from to much dust build up inside the system, causing it to overheat and shut itself down.

A:Computer slow after power supply replacement...

You would have to ask them for a list of that which they did.

What brand, model, model # PC, or same information for the motherboard?

Computer specs would be helpful.

Which ;power supply was it: brand, model, model #, wattage? Same for now?

If you aren't happy, take it back & have them install a new power supply and politely insist that they demonstrate it to you before you accept it back.

Start the computer, note time from start to desktop appearance or log in screen appearance.

Start the computer in safe mode & do the same.

To start in safe mode, start > run
type: msconfig
boot.ini tab
put a check in "safe book"
exit without restarting
Shut down.
Turn on.

Today I switched on my computer and it wouldn't turn on. I had a feeling that it could be something wrong with the power supply, so I took it out and connected it to another computer and it did not work on this other computer either! However, the motherboard light turns on when the power cable is connected to the power supply.

Would this mean that it is or is not the power supply that has broken?

I was thinking that it could be my front panel connectors that could be causing the problem but I'm not sure after I tested the power supply on the other computer and it wasn't working either.

Many thanks for your help.

Last night there was a huge lightning storm near my house that caused the power to go out, and when it came back my computer refused to power on. It was plugged into a surge protector, but I figured the lightning had somehow zapped the power supply anyway. So I went and bought a new power supply, reconnected it to everything, and the computer STILL doesn't power on. The light next to the power switch doesn't even light up. What could still be causing the problem? Even if the motherboard were zapped, wouldn't the computer itself still power on? What can I do to find out where the issue is coming from?

Hi, I'm not sure why the computer is doing this, but whenever I plug in the computer, the power supply starts buzzing, and the LED light that shows if the computer is on automatically turns on once I plug in the power. And if I push the on/off button the computer doesn't respond to it at all. Not sure why this is happening, but please help.

Sounds as if the Power Supply has gone out, or the MotherBoard has shorted and is gone. The easiest way to check would be to find a replacement Power Supply and install it.

I am trying to find a replacement powersupply for a hewlett packard computer.
The computer I have will run for a short period of time then it will shut down completely. I can restart it after a short period of time. My question is what type of powersupply does HP use. Is it a atx style or something else? I am at work and I am trying to get the model number from home. I was hoping that someone would know off the top of their head. thanks for all the help.

A:hewlett packard computer power supply

First off, you'll have to be a lot more specific. HP has made many computers over the last couple of years, and there are a variety of power supply styles.

From your description, it's not possible to determine if it even is the P/S that is the problem, what makes you so sure that's the failing component? This could be a cooling issue because the processor fan has failed, and the machine is shutting down on a thermal cutout, for instance.

My dad said he came home the other day and smelled something "electrical" burning and traced it to the computer, so he unplugged it.

I plugged it in to test it, and got a loud horrible sounding beep (so loud i'm not sure if it came from speakers or the hardware??) and then nothing happens Won't boot up. I just hear a vibrating/sickly humming sound in the box that is in the back of the case, with a fan, and as far as I can tell the fan is still spinning, so the noise most likely isn't the fan. Would this 'box' be the power supply? I am guessing so since this is where the power plug goes in at. Also, if it is indeed the power supply, would this problem inflict damage on other components?

A:Computer won't turn on at all; Curious power supply behavior.

A lot of computers do that first burst of power, I can name 4 that I have had recently, and they are all happy and running (one in now my server), so this is not an issue. Does the computer not turn on at all? If it does not then I ran into one mahcine about a week ago that would not turn on at all, power supply was good, giving out 5 and 12, tested RAM, vid card, HDD's, CD ROM, mobo by itself, and reseated CPU. Nothing, this made me mad. So anyway I pulled the CMOS battery and boom, it worked, long story short it was a CPU recognition issue, dumb I know how it would not even turn on.

Tried pulling the CMOS battery on the new mobo? It is possible to get bad CPU's, I know a guy who went through 3 AMD's before he got one that worked, I do not think the issue is your power supply, it could be something is grounding out against the case or a bad CPU.
