I have been using my computer normally for several month, but out of nowhere, today it starts to randomly crash and BSOD. Symptoms: A few minutes after boot, applications would randomly crash, then after a bunch crashes at once, windows would freeze up for a second or two then go into BSOD. My minidumps suggest that it crashed in address ntoskrnl.exe+7cc40 What could be the cause? Here are the dumps: http://dl.dropbox.com/u/3085200/dumps/dumps.rar I tried to do a system restore to the last restore point I had but nothing changed. I did the window's memory diagnostic tool and it reported no problems. Been running memtest86+ for the last couple hours and so far no issues either.
