It's been going on since I've had my PC. I had it built with all new parts from someone who I consider trusted (If I can't find a Fix here they will help me).
It happens mainly while playing games, anything from League of Legends to The Elder Scrolls: Skyrim.
It seems to happen at random intervals just more often while playing games. It says there is either a hardware or software error, I have yet to copy down everything but I don't think there was an error code.
Seeing as It's happened since I've had the computer (At first I thought it was driver
problems but after updating I've realized otherwise). This eliminates the possibility of anything that I can remove physically or uninstall from the PC that may fix it (That I know of).
It didn't happen while under stress tests by who built it for me, if that's of any help.
