My computer spontaneous reboots quite often (XP), and has so for quite a while, through severeal clean installs and almost every piece of hardware has been replaced. It started doing this maybe 2 years ago, once or twice - now it does this maybe 2-5 times a day. As topic says, I need help analyzing the minidumps. What can been seen in event viewer as last event before minidump, seems to be completely random.
