Hey, first post. Woo. I'm having some issues with my PC. This is not a new thing, it's done it since I built it, but have only just got around to fixing it, and you'll see why as you read on. For some reason, after my PC has been shut down, for any length of time, be it 2 seconds or 2 days, when I turn it back on, it will bluescreen at a random moment, usually about 5-15 minutes after it boots. It will do this either once, or twice, but when it restarts either the second or third time, it won't give me a BSOD again, until I switch it off. This hasn't bothered me in the past, because I used to leave it on 24/7. But recently I've been needing to turn it off, and is an absolute pain-in-the-***, because I have to wait for it to randomly bluescreen before I want to do anything productive with it. Sometimes, it won't actually bluescreen, but it will cause Warcraft 3 (The most noticable case) to crash, and give a memory error, and just restarting the PC will be enough to count for a BSOD (To reach the third or second time before it works). It will only BSOD when I'm doing something resource intensive, eg. Playing games or watching a movie. Just browsing the net doesn't seem to do it. The BSOD errors I get mostly are: MEMORY_MANAGEMENT, IRQL_NOT_LESS_OR_EAQUL and PAGE_FAULT_IN_NONPAGED_AREA. It does it in both XP and Vista, and clean installs do not make a difference. This leads me to beleive it is a driver or hardware error. If any of this makes any sense, I need some help D: It's driving me mad. I can supply any extra information to help diagnose the problem, and am quite commputer literate. Thanks in advance!
