Hi,
I just bought a used GTX 750 1GB for my secondary PC, i stress tested the GPU by Furmark several times (2-3 minutes each run) and it did not show any problem.
During PC usage displays gets turned off after some time randomly, but PC remains on since when i plug the VGA cable into onboard VGA port the system shows display. It only gives back display from GPU when i put the cable back in GPU's VGA port and restart manually (if i restart while the VGA cable is connected in onboard VGA port and then put cable in GPU while PC is already on, it does not give display).
