I am having a problem with xp restarting itself before it reaches the login screen. I have an asus a7n8x-deluxe V2 with an amd 2700+. If I set the mobo at the correct speed then xp restarts, if i set it to a default (1500+) then xp runs perfectly. No virus infections, clean install (tried several times and different hard drives). So I am forced to run my 2700 at 1500. Any ideas?
