Help system is freezes

[travishuynh]

Hey guys i recently made my new build

i5 3570k
ASrock pro3 Motherboard
Hyper212 evo
2x1TB Hitachi
and a 6950 unlocked to a 6970

for some reason it keeps on freezing for no reason i had the same reason with my old build which is why i switch to a new mobo+cpu which i thought were the problems

i am either guessing the 6950 or the Hitachi is crashing, that or my system is to hot since i have a cheap NZXT case

if anyone can help it would be helpful

PSU? Did you use the old one when you upgraded, and what is it? Have you checked your temperatures? What are you doing when it crashes?

i mostly game and it just crashed while i was watching a 44 minute youtube video earlier

yes i did change my PSU sorry about not saying that

before i had a 650W Earthwatts form Antec and i bought a 81+ brozen Modular PSU from Seasonic

Also forgot that i am still reusing my 4x4gb Corsair XMS3 1333 ram so that is also a possibility for the shut down/ force reset
