so i just built a new pc and games keep crashing after a few minutes. This has only happened while gaming, i took out 1 stick of each ram and tried each stick individually and it crashed so i don't think it is the ram.
PC SPECS
Pentuim G3258
XFX R9 380X 4gb
16gb gskill ram
and an rosewill 600m valens psu
can it be a dead gpu?
