computer shutting down

[JoeyM]

My computer keeps rebooting a second after the Windows screen (with the blue "loading lights" underneath) starts.

I'm not sure where to start to fix the problem. There have been no changes to the system lately. I use windows XP, an Abit p4 motherboard, Antec power supply, plenty of ram. The OS is on a pair of Raptors in a striped RAID Array.

I'm thinking maybe one of the hard drives has crashed but would the Windows loading screen even start if that was the problem?

The power supply seems to be working.

Is something causing the reboot? Even safe mode makes no difference.

Thanks,

Joe M.

I would suspect the PSU first off.

You might want to go into BIOS and make sure the Fans are running (properly).

Also check your CPU temps. If your cooling/heatsink came loose, your CPU may be overheating and causing a reboot.
