Earlier this year I had a problem with my computer. When I was using it to play games and perform other quite CPU intensive tasks it would become sluggish and laggy. Usually a restart would fix it for a while. The problem got worse and worse until it started to turn itself off when things got rough. It would do this more and more frequently and easily to the point where it wouldn't turn on. After some investigation I found that my PSU was fried so I bought another one and replaced it. Problem solved. Until now.
The same thing has started happening, and it's now at the point where it's turning off frequently under heavy use. Surely the issue cannot be the PSU again? There must be something else causing it to fail and in turn damage my PSU. I get no BSOD, no warning or anything, just an instant trip and the machine is off. Checking the logs doesn't seem to reveal anything either.
Don't suppose anyone has any suggestions of what to do to try and find out what the issue is or has any insight into what the problem might be?
Thanks in advance.
