I have an HTPC i built about 2 years ago, everything has run great. A few days ago i bought an MSI radeon hd 7850 twin frozr video card to put in so i could do some gaming on it. I put it in, installed drivers, went ahead and gave it a small over clock through msi's afterburner software (went from 900mhz to 1000 on core and 1200 to 1300 on memory). from what i have read, the 7800 series radeon's should overclock well beyond that pretty easily. then I watched some tv on it. after about 2 hours of that i loaded up crysis 2, played for about 5-10 min, it ran great, and then computer shut down randomly. and would not restart. i opened the case checked all connections, everything was fine, still wouldn't turn on. I unplugged the pci power adapter from the card and it started up and is running fine.

after running for a few hours fine with the card connected, why would it all the sudden not work anymore? any ideas? specs of comp are listed below.
I assume it is power related since when i unplugged the pci power from the card it ran fine, but a 520w power supply should be plenty of power for what i am running:

oh i also have a blu ray drive, an ssd, a 750gb hdd, and a ceton inifitiv 4 pci card, dont think those should matter though.

right now it could have been two issue. one the card itself had a bum gpu chip. when it was loaded and started to run at max temp and heat..it died or a part died on the card. or in the hptc case there no airflow and the card was cooking itself. the last would be if the power supply leg that gives power to the video card if it died on you. right now i take the card and try it in another pc to see if it is working. if it works fine (under gaming or stress) then it the power supply on the hptc.

Did you have your VGA's fan run at 90-100% while at full load? It might have overheated if not.

I had random shutdowns before in my system, because of my VGA card, i changed my powersupply with a branded one and everything works fine now.

Is your powersupply new?
