This year's dust harvest is a bountiful one. I'm not sure I can bring myself to clean it out.
I thought it might be a heat issue at first, but I'm not inclined now to think it is one. The problem just seems to random. The fans are all working and the problem is intermittent. For instance, I was playing WoW for like 4 hours with no problem, took a few hours break, and then it gave me a BSOD in about 20 minutes game time.
If it were heat, it would seem that the computer would simply keep locking up or rebooting almost immediately since I didn't give it time to cool down, but that doesn't seem to be the case. Of course, if I keep trying to play a game, it'll keep locking up after another 5-20 minutes, but if I just leave it on or do something else it's fine.
Appreciate the suggestions so far guys.
Not to beat the dead horse but games are very processor intensive and caue a lot of heat build-up. You just leave it on or do something else and it's fine? You play a game and it locks up after 5-20 minutes? I had the exact thing happen. It was heat caused by mucho dust and a fan that wasn't cutting it.
Also surprising to me was the fact that some games caused more heat than others. WoW is not as graphically demanding as other current games so it might make sense that it would be okay.
It could very well be something else but until you rule out heat and dust that's where I'm putting my money. If you want to pursue the heat angle further, download a copy of Motherboard Monitor, check your temps and post them here.
