Using a program i checked to see if CPU/ GPU temps were ok, and they were fine.
At first this seemed to only happen when gaming, with the time before going black becoming shorter (around 1-5 min in game) but then also started happening while browsing. It started a couple of days ago, while gaming (old games, so cpu/gpu technically shouldnt be being overworked) my pc screen would go black, fans to full speed and would only shut off if i held the power button. I am by no means a pc-expert but have tried to fix this myself with the help of older threads in this forum, unfortunatly to no avail. Since a couple of days i've been having trouble with my pc, and it seems to be getting worse.
