PC is crashing under load

[Tsviki]

So every 95% of the time im going into game (even just opening it), I can hear the GPU start kicking and then my PC crashes, and then reboots back normally.

This is going on for like a month.. in that month ive reset my drivers, formatted my pc, went to a lab and got my GPU testing (came out to be fine) and even testing it in another room since my room sometimes go crazy with the electricity. 

 

Im pretty sure its the PSU. (by "pretty sure" im like 99.9% sure..) its a Antec TruePower Classic 750W 80+ gold.

Im sad, help.

What are your PC specs? I can't see it being too much for the 750W PSU to handle, but who knows.

what kind of lab tested your gpu? lol

 

also if you are 99,9% sure it's the PSU, then why not swap it?
