Ive been having some issues with my system for a while.my pc screen randomly glitches and goes blank for no reason which locks up my pc and forces me to hard shutdown my pc by holding down the button.this issue is so rare that it happens to me once every 4-5 months.i thought it was my mobo so I got myself san msi z270 gamming m7 thinking that it will solve the issue.suprisnignly it as I went back to my pc I saw nothing but a blank screen and my pc locked up for the 4th time.now I'm thinking it could be the gpu.

so with the symptoms I described,is it possible that whats happening to me could be a gpu issue?or even a vram issue?if not what could it be?

Gtx 970 strix

Msi z270 gamming m7

I5 6600k

16gb ddr4 ram

Corsair rm850i psu

Btw i forgot to mention i tested both of the ram sticks individually on memtest 31 hours on each stick an there were no errors.so i can confirm that theres no ram issue.
