My computer turns off on its own after about 2 minutes. I recently bought a processor and installed it without a problem. The thermal paste came pre applied, and the computer just started shutting down after a month of use after installing the processor. I also bought a new motherboard recently, and it installed without a hitch. Had it for 3 months now.
Here are my specs.

Asus motherboard M5A97 LE R2.0

Processor Description: AMD FX-8350 EIGHT-CORE 4GHZ 16MB 125W AM3+CPU


Description: Visiontek Radeon HD 6850 1GB GDDR5 PCIe

Okia switching power supply 650ATX

8gigs of ram, corsair and crucial.

That's what I was thinking, but what is your reasoning for thinking this? It is the only part of my computer that has not been replaced. The psu that is.
