Help me revive my dead computer please

post #1 of 20
Thread Starter 
+Rep to anyone who can say anything helpful.... I am in need of it

Here is what happened:

I used my computer at lunch on monday, everything was 100% normal. Left it on and went back to work. Came home and it was off. Tried to turn it on and nothing happens. My PSU has a power switch that lights up when plugged in. That didn't light up so I assumed the power supply died. I mailed it back to the manufacturer and they are going to send me a new one... which is good but then yesterday night I got a loaner PSU from a buddy at work. Hooked this one up and STILL nothing. The motherboard power connector and the ATX 12v connector are both hooked up securely... I unplugged everything except the vid card, the mobo and 1 HD; hit the power button and nothing happens. It's as though the switch was broken... I'm going to try using a screwdriver to test the power on pins at lunch today but I am skeptical that the switch on my case just broke randomly...

Some other info: The computer was not overclocked or over volted at the time this happened. About 3 weeks before, I had been getting crashes and high temps (due to lots of dust on my heatsink I think) so I turned my overclock off completely. I don't think that a power surge destroyed my system because everything else in my apartment is still working, including the cable modem, my monitor, printer, soundcard etc, which are all hooked up to the same power strip. The light on this power strip still indicates "protected". What could cause my system to just die like this...????? I'm totally at a loss.

Does this mean my motherboard is dead? What can I do to help diagnose this problem? +Rep to anyone who can say anything helpful.... OC.net helped me build this machine a year ago; I'm hoping you can help me revive it now... and rebuild it if it comes to that.... DAMN!!!

Is it possible the fuse has gone in the plug?

Well alot of the time this is a sign of a dead motherboard which can happen out of the blue like with you..Make sure just again that your CPU and all cables are correctly Secured to motherboar board. Also try only connecting the bare eseentials and try again all you need is the ram cpu and Vid card so just try that..Also try booting wit just one stick of RAM and test each stick. Also try using a differnt wall socket to get power from as you never know and try using a different power cord as if there was a power surge of somekind the fuse in the plug may have been killed as such.

I'd love to help you diagnose the problem, cleared cmos and reset the jumpers? I had the same problem..many times

Well, this is worst case but it has happened to me before.

When you went back to the computer did the area smell like burnt silicone? Even if it didnt i would check the CPU, look for burn marks or melted chips.

I came home from work one day and found my AMD to be in smoke because the cpu fan failed and amd doesnt have a temperature throttle or anything (this is why i am an intell fan now). Give it a look, it may have got too hot and burnt up.

Well AMD do have thermal Control its called Cool and Quite if you have it enabled in the bios that would not have happend but we all make mistakes eh.

I doubt any type of chip/transistor/resistor cap ect would burn up on an epox board all the chips caps resistors are very high quality. If your psu died it could have sent a surge onto the motherboard killing something. Does your board have diagnostic led indicator if so referr to the mobo handbook

That would be a bad scenario...it definitely could mean your mobo is dead..thats what everybody told me when my psu burnt out (turned out to be that) thank god it wasnt but that could definitely be the case especially if another psu didnt work..resetting the cmos didnt do anything?

edit: and also i agree with chosen if your mobo has a manual and an led check it out that could diagnose the problem right there

Yes if a PSU received a large Surge sometimes the surge will carry on into the rest of your PC causing some damage. Im not sure what a Blue forton is like so i cant really comment.

The obvious thing is that your mobo doesn't get any power, so the problem can be either in the wall (you could try plug it in a different source), dead PSU (but I don't think so, since the other behaves the same) or dead mobo wich is the most likely, just my pow.
I've seen a mobo crashing like this, at first a friend had to drop his OC from 220 to 200 to gain stability (barton 2500 on AsRock K7dual...), after a week from 200 to 166, and it finaly died.
To find out if the mobo is dead there is no other way but borowing a working piece and test the other components on the new mobo.
Good luck!
