My computer would occationally reboot itself without warning. I tried disabling the automatically reboot option, but instead of rebooting, it just gives me a blue screen. Help.

Usually the blue screen gives information, though cryptic, which can help locate the cause of the error. Does this error happen randomly or usually when performing a specific function? Any event viewer errors?

It happens usually when I'm playing games. In the event viewer it just says that my computer has rebooted from a bugcheck.

I believe this used to happen to me sometimes while i played HL. I think i just updated my video drivers. Maybe you could check for IRQ conflicts.

Help me ! I have the same problems, cheked everything, reformatted disk, reinstalled software, scanned for virus, tried another motherboard, video card etc.etc. And it still happens !!!!!!!!!!! Heeeeeeelp

This was actually happening on my Windows 2000 computer. I did some digging recently because I was having the same problem or at least it had the same symptoms. I found after analyzing the minidump files being exported by Windows 2000 that there was some kind of NAV***.exe program that showed up a lot. I didn't actually understand any of the randomness of the debug. I began searching again tonight and found this article on Symantec's Site: http://service1.symantec.com/SUPPORT/ent-security.nsf/docid/2002071208532048?Open&src=w&txt=s Basically what it refers to is that the Kernel Driver which is installed by a Norton Antivirus program causes conflicts at times when it is scanning a file for realtime protection. The website has the whole fix including added a DWORD value to a certain area of the registry. It's hard to explain exaclty what happens, but take a look at the article. And if you don't have any Norton Antivirus program installed, well then I don't know what to say. Sorry, I tried. I hope this helps.
