Every time I play a high end game or if I stress test pc. my monitor goes black or pc shuts off with fans whaling away and I have to do a hard reset. I have replaced cpu thermal paste with artic silver (pea size) works perfect when browsing the web or watching a movie.
any help would be appreciated.

stress test results

prime95 for 10 mins stays on
cpu temps are 41c -43c
when idle my temps are about 24c-27c

Furmark 10 mins stays on
gpu temp 79c-80c
when idle temp is 27c

running both at the same time pc shuts off after 3mins

Depends on the line. The "Stallion" and "Green" lines are not good for any use. Pretty much just stick with the more expensive Rosewills and you will be fine.

bought the new psu still having the same issues. went to a shop near by all they had was a Antec HCG M HCG-850M 850W ATX12V.

only does it on rise of the tomb raider and when I test both furmark and prime95.. all other games work fine. any ideas on what it could be?
also tested memory with memtest86+ no errors after leaving it running all night.. I'm lost here ..

played Rise of the tomb raider for about 3hrs straight with fxaa on and pc didn't crash or shut down once wondering if that was cause of anything. Still I'm clueless why it was doing it in the first place.. i'm sure all is not well and will continue to test out.

I'm confused guys I don't know what the problem could be..I changed the PSU still doing the same thing. temps are normal nothing is jumping up to 90c
changed the termal paste on my gpu. took the pc apart and checked the mobo for burnt or blown caps everything looks good.
is there a way to go into bios to change this feature..?
