Sudden shutdown now no boot :(

post #1 of 47
Thread Starter 
So I was watching a youtube video on my sig rig, when all of a sudden, it shut down (like it lost power), then proceeded to attempt to boot back up. It went through this cycle of shutdown, restart several times before finally shutting down and staying off. Here's my observations so far:
  1. Both the PSU and mobo have power (as indicated by a lit standby light).
  2. Pressing the power button does nothing 9 times out of 10. The last time I get fans and lights for about a second then nothing.
  3. A visual inspection showed no blown capacitors.

I have not changed anything on this computer in over 2 years, so it's not a component change that could've done it. Any suggestions on where to go from here?

Try removing your 8800 GT then try to boot up. If it doesn't work try to boot with only 1 ram stick.

That's crazy. I'm having the same problem right now. I clicked a vimeo link, pressed play, and my PC shutdown and hasn't been able to boot past bios since. I've changed out ram, video card, processor, unplugged cd drive, and unplugged each HDD seperately.

Tried removing the battery to clear the CMOS?

Yes. Tried another battery as well. The other battery is 3 years old but was only used from Jan 08 -April 08.

Do you know what was your CPU temp before shutdown?

It was normal. I have it OC'd to 3.8, but it never got over 52C under full load

Ok did you try to remove your 8800 GT and your ram sticks and try them one by one?
I hope it is not but I don't know I feel it is the 8800 GT. 8800s were having heat issues and have very high failure rates.

I'm not positive but I'd imagine I was running a regular temp as well unless something went terribly wrong. I run my PC with speedstep on and never get higher than 50C or so.

Ok so I've reset the CMOS via pulling the battery, tried pulling the vid card and a stick of RAM all with no luck. HOWEVER, I've noticed that if I unplug the PSU and plug it back in, it will start up for a second every time once. Then I get nothing unless I unplug and replug again.
