My PC keeps turning off...please help

[JustinLovesIzzy]

I am running all the current driver and have had no problems with game, until last night. During a CM run, my PC just shut off, i thought maybe it was a power surge, booted back up and played until maintenance (4.5 more hours). Today after maintenance, I've tried about 10 times to play, everytime, my PC runs the game fine for about 5-12 minutes and then shuts off. No overheating. Pristinely cleaned. Drivers up to date. Uninstalled and reinstalled game. Defragged. Tested against other games, skyrim, fallout new vegas, no problems. I have no idea what is up. But I know it has to be a compatibility problem with game. I really wanna play. But If i can't get this fixed, I'm gonna have to cancel. I have a 90 day sub about to charge on the 5th. Please help. Anyone with similar problems or PC knowledge. Or SE itself. I WANNA PLAY!

Sounds like you are overheating. if you have poor circulation, or a bad seat with your CPU to your MB this can happen. Or your power supply is failing or another component. Those are the only reasons I've ever seen for a pc just shutting off, and I've seen a lot of them.

my card isnt overheating, running at 40 degrees.

Do you get BSOD?

Contrary to what you may think, this probably is overheating. Mayhaps it's your power supply overheating, I had a similar problem once before where my power supply was inadequate to handle the parts I had installed and kept overheating. Have you recently upgraded some component on your computer?

Try replace your power supply!

the most recent upgrade i have made to the PC was the card, but it was a downgrade from an AMD card that was overheating due to this game. the card i have now is much smaller, efficient and takes less power. I also have been running that card since Aug 9th with no problem. So no changes. why would my power supply be overheating only in this game and nowhere else? that isnt sarcasm, btw.

BSOD? sorry I'm a little bit of a noob.

He didnt get BSOD probly .
I have had it too , underclocked my graphic card ( not heat issues at all and no problems with computer) been searching all over...
It runs fine now after downclocking my videocard back to standard/factorysettings.... the videocard isnt the problem however.
I am pretty sure your PSU is the problem , because once i did some powersavings on my system, the problems were gone .. so i need a new PSU

P.S. it probly is PSU overheating indeed.
I know it is because when it shut down ,, and restarted computer inmediately it would shut down again ,waiting for a few minutes , i could boot normaly and not get powered down , untill after playing game for some time.
I haven't checked yet with adding an extra fan to the PSU , i probly buy a new PSU later , so i just play on more powerfriendly settings untill then .
