Computer shutoff not temps!

Ok, I cannot figure this out. My computer just a few days ago started turning off like someone pulled the plug when playing games such as csGO, Rift etc. I have run tests with furmark, monitored temps with fanspeed and EVGA Precision. Temperature is not causing these shutdowns. The latest was on Rift with high graphic settings. GPU temp didnt get above 52c and both cores didnt get above 38c. I uninstalled ALL drivers for my GPU and installed drivers that I know are stable because....well i used them with no problems. I tried a system restore as well earlier this morning. Im at ends. My last thought I can muster is a failing PSU. Any help is highly appreciated. :cry

 

The most reliable way I know of testing a PSU is by Thermaltake:

There is also an outside chance it could be the HDD cutting out, but I would rule out the PSU first.

 

Thank you for the reply. I should have stated that I had my memory tested as well as my HDD and both came back in good health with flying colors. Brain is fried, wasnt thinking rolleyes
