I can leave my computer running 24/7 for days without an issue.
I can surf the net for hours no problem.
But lately if I log in to WoW my PC will randomly shutdown. Just like someone ripped the plug out of the wall. My PC is on a surge protector and nothing else on the cord seems to be effected.
My best guess, based on my vast googling ability, is that something is overheating but all my fans are working and the case doesn't feel unusually warm/hot.
Sometimes I can turn it on and play for another 2 hours, sometimes it dies as soon as I click the WoW launcher. Has never happened when I'm not playing WoW and only started this about 2-3 days ago.
I can get my WoW fix at work but I can only do dailies and trade skills there. That's only going to hold me over for so long.
