This mainly happens while watching videos on sites like youtube, but also happened on medium gpu usage games. Nearly impossible to reproduce consistently so I don't have a video to show it. Usually happens around 10 times a day, with a much higher rate of happening after leaving the PC idle for a while and starting a video stream.
Tried everything, like changing PSU, using one cable per PCI-e power slot, drivers and bios are up to date. Even thought of RMA'ing the card but I can't afford not to use the PC for that long.
Anyone else with this issue? Or is this a known issue?
