Help !
My PC today seemed to reboot itself for no reason. the second time it never recovered. hanging in the startup.

Tried a safe start but it rebooted trying to start this way. I removed all the peripherals & restarted and it went into windows fine, thought I'd isolated a cause !. added the keyboard & booted again. this time no screen at all. removed the vga cable & screen notices loss of signal, but no text or anything shos from PC. LED at orange as well , not green.
Must have some hardware failure, normally I'd suspect the video card, but for all the preceeding problems.
Any ideas on componant failure ? I'm a novice so please bear with me. Does this sound like any other componant failure.. memory, processor ?
p.s. Left it to cool down in case heat related. (fan works)

Windows XP Home.

Try finding the CMOS jumper on the mb and tripping it. Then try restarting it. This can sometimes fix this kind of issue especially since you pulled everything out already. Then try it just with the most basic, Video card, one stick of memory and the cpu and see if it boots up.

I've located the CMOS jumper JP1, pin 1-2 = default
2-3 = clearing.

Do I move the jumper to 2-3 then restart or just short 2-3 without power on. then restart.

what will clearing the cmos mean to my system, will I need to go into BIOS & change settings ? (assuming the PC starts of course)
 
Usually just removing the jumper, waiting 5 seconds and putting it back should be sufficient. Releasing the jumper, assuming it works will reset your bios settings and force you into the bios the first boot. You then just have to make the neccessary changes.
