So I was playing ACII on one screen and watching a movie on my second screen. when everything just shut off. Like the plug was pulled. I powered it up and turned on the tuning utility and the CPU said 76c but before I could manually turn up the fans it died again. Now all the fans come on and the drives seek but I get no post sounds and the computer does not respond to the Power and reset buttons only the PSU switch can turn it off once its powered.
I have let it cool for an hour and it still won't come on.

I moved to a very remote location and I am out of AS5 so when I unpacked my computer last week I put the heat sink on with the residue remaining from before. I know this is un-kosher but I monitored it for the first week and it stayed at reasonable temps under light use. Today I guess I forgot all about the AS5 that still hasn't arrived in the mail and started multitasking. Did I nuke my CPU like and idiot or Could it just be the PSU and A coincidence (PSU is 10 years old, new one of those is also on the way) What should I check for?

So far I have tried clearing CMOS, re-seating all hardware, unplugging the PSU from the wall & the board and swapping out video cards for a known good one just to rule that out.

Which CPU have you got? I doubt you have nuked your CPU, that's really hard to do but it could be something to do with the connections between the PSU to the motherboard as you are getting no post sounds. I think you should wait until your PSU comes and then do a check and report back. Also what PSU have you got and what wattage? And what is your overall system intake. Those will be useful to me and others.

Sorry, I'm running the system in my SIG(re-entered below). I know 500w is just enough for my system and when you factor in capacitor aging, its probably just not enough anymore. XFX 750w 80+ Gold is on the way and so is an FX-6300. So as long as its the PSU or CPU I have a fix coming but I'm hoping its not the CPU cause my freind wants to buy my PII X4 970 off of me.

Yeah, I can wait it out, I was just hoping there was something else I could do to revive it because I like playing my PC games and the family is out of town for a few days so I actually get the chance to.

MoBo--ASRock 970 EXTREME3
CPU--> 3.9ghz--AMD Phenom II X4 970
RAM (AMD)--4x4GB DDR3 1600 CL9
GPU--XFX HD 6770 1GB
HDD--WD750 72,000rpm
PSU--Antech SP-500

Yep, XFX 750w 80+ Gold came in today and after giving the old PSU one last shot I switched to the XFX and all came to life :)
My guess is that the 3.3v or 5v rail went out on the 10 year old Antech SP500 and that's why all the fans and drives spooled up but none of the electronics did anything.
Now to install my FX-6300 using (AS5 this time) and see how soon I can push it to a stable 4ghz.
