ok...so i am running a xp 2200 overclocked at 1.91 gigs and i find its unstable b/c of shutting down and attempting to reboot....thing is.....when it goes to reboot my monitor starts to come on but before anything can happen it acts as if its off and the system freezes....so i go and reset my jumper remove the motherboard battery to reset the bios to the original settings and then it will reboot....obviously the processor is then underclocked on the default settings and i dont mess w/ them and i find that when i go to reboot again it does the same thing....is the motherboard trashed?....if so why will it boot up and still run fine once up and running or was it just heated up to much causing the computer overheating protection on my motherboard to keep it from rebooting?....any advise or insight would be greatly appreciated.
