Pc crashes after 2 to 3 hours of use.

Ok so my rig is the following

i7-4790k (stock)

Xfx r9 270x

asus z97 ar

lepa maxbron 1000w bronze

hyperx 8gb 1600 ddr3 rqm

120gb ssd, 1tb hdd

cooling is not the reason for crash.

I think the psu could be couse regardless of it being the cause I'm upgrading to a evga supernova p2 in the upcoming 2 weeks.

the issue is that the computer just freezes and the image goes white with a lot of pixels and sound freezes as well after about 2 to 3 hours of constant use, regardless of it being use for gaming or a movie. Currently the gpu is connected to a single cable from the psu that has two 6-8 pin connectors. I was also wondering if that could cause my problem and if I should connect two separate cables to the gpu even if the psu only comes with modular cables that have 2 6-8 pin conector in them.

You could try monitoring your memory if that could be the problem. your GPU might just be dying and just up and crashes after running for a while
