I labelled this under cooling because I can't see what else can be doing this. Sometimes I can go a full day without my computer freezing, others, it's more common. I can only presume it's down to heating as it has been doing it since I got it. All drivers are up to date, the computer is almost dust free and I always keep the Graphics Card Drivers the newest version. Here's my temperatures without playing a game. and this is it whilst playing SC2. any advice is heavily appreciated.
could be a bit of faulty ram. maybe set the ram back to default setting in bios and see if that helps. or test a stick at a time. But if its only now and again it may be a long process
if it was the ram wouldn't it affect the computer in general? if i don't play games for two days and leave my computer on for two days it's fine. just seems to be when the graphics card is getting a work out
That AUX temp looks a little on the high side. What is that sensor referring to? It could also be a PSU problem that only develops under high loads. What PSU are you using? How old is it etc.? If possible swap out the PSU with a known good unit to test.
