My husband's XP Home SP2 computer which is less than a year old has suddenly refused to boot. It has got into a loop sequence where it starts to boot then after a few seconds shuts down and immedately starts up again and only pulling the plug can stop this. During the attempts to boot I cannot open the CD/DVD drawers to insert a disc and it does not stay on long enough to get in to BIOS or safe mode. The XP logo does come up on the screen sometimes but never longer than a few seconds before it all starts again.
Any ideas what is wrong and what I can do before we call Evesham out please? Although the computer is new my first thoughts are failed PSU, or some sort of virus despite having AV of course.
