Computer shutting itself off without warning, not overheating.

[mrtoasterwafflez]

Whenever I run any kinda of CPU heavy processes such as games, this is where I've encountered my problem the most. My computer will completely shut off without warning. I've checked the temperatures and nothing is running hot. I recently replaced my PSU so I know that's not the problem. Is there anyway to check if my CPU is bad? Or is there a fix for this? Thank you.

If you are sure that it is not overheating (and it could be motherboard or GPU overheating, not just CPU overheating), I would be looking an memory first.

Memtest86 is a good place to start. What is your complete hardware configuration?

Yeah I'm sure it's not overheating, But i found out what the issue was and I feel reaaaaaaallly dumb. I didnt fully plug in the 20+4 pin cord into the motherboard. only the 20 pin part.
