How do you know it's the PSU?
What else can it be?(thanks for the quick answer)
Just about anything. RAM is a common one. Motherboard. Overheating.
I usually start be taking temperatures during an AIDA64 stress test. We can do this here.
@JerryLP, Please download
AIDA64 Extreme, drop down the Tools menu across the top, select System Stability Test, select everything except for local disk and run the test for ten minutes. Take a screenshot of the Clocks and Statistics tab every thirty seconds. Save these screenshots immediately; this way, if it crashes, we'll be able to tell if a component displayed abnormal behavior right before the crash.
Update: Make the test fullscreen so all stats fit on screen at once.
