Built my PC about a year and a half ago (bought from iBP) and have since replaced the PSU, all stock fans and the RAM. Been playing Overwatch/Borderland Pre-Sequel recently and I can only play for about 5-10 minutes on each one before the computer crashes. Temperatures are stable hovering at around 60 degrees c at the time of the crashes. The activity on the GPU and CPU seem fine (from what Speedfan and AMD Radeon are telling me). I've no idea what can be causing this. I've ran into this problem before but it only started getting bad again about two days ago, with about two months since the last major occurrences. (I also run Chrome with YouTube open while playing Pre-Sequel.) I also got an IRQL_NOT_LESS_OR_EQUAL error while playing Pre-Sequel.
