computer constantly cycles

Last response: in Motherboards

I've got a computer that constantly reboots. I thought it might be some sort of virus and formatted. It ran fine for a while, now it has started again. It reboots at the Windows XP screen before the GUI starts. Could this be a motherboard or other hardware issue. I do not know what kind of motherboard it has. I'm running windows XP Pro

Can you try booting in safe mode? (F8 I think.)

Could you try to post as much as you can find on your system?
Harddrives, optical drives, RAM, CPU, mainboard (open the case), PCI cards, power supply, CPU cooling, videocard.

When did the problem surface? Is it on a new system?

We had this same problem when we installed
a new Radeon AGP video card: we think it
was some kind of conflict between SP2 and
older drivers. (We are told that SP2 changed
almost 25% of Windows code: THAT'S A LOT!)

If you are using automatic Windows Update,
XP may have upgraded itself and
rendered your current video driver obsolete:

I would start by updating your video driver:
that fixed our problem permanently. Also,
we had to switch back to "programs"
instead of "system cache" in:

My Computer | Properties | Advanced | Performance
| Advanced (begin this sequence with a right-click)

"System cache" caused a subtle overlap between
reserved video memory and Windows memory
management: this problem and the fix are
documented at the ATI website.

When updating drivers automatically,
be sure you're connected to the Internet,
so that Windows can access the Microsoft
website and do the searching for you.
