Sometimes my GPU driver crashes and recover. Edit: more info; DDU is used to uninstall before installing driver for following GPU. NVDIA Gefore Experice application is used to install the latest driver. I don't know how to overclock things so the GPU is installed as it was bought. The computer is used just for Official work and watching 1080p movies.
You should check your gpu temps while under load to get a more accurate idea of how hot it's getting. Updating to the latest drivers from Nvidia may help. The output of your power supply will affect your video card too, too small or a cheap name brand will under power and cause a crash
Which GPU? Which driver? Is it overclocked? Have you used DDU to remove the old driver in safemode and reinstalled the driver again in normal mode? TBH that post has no info at all, no way to help, pointless thread
