My PC keeps turning off...please help

[wolfsspirit]

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 .
