Thank you all for the suggestions.

Mine is running Service Pack 1. I think my problem comes from a cheap IDE
66 card I installed recently. After taking it out, I don't have reboot
problem anymore for the last 3 days. It might not be the card itself. With
this card added, maybe my power supply (300W) isn't big enough to provide
all the power needed.

I have a video card, NIC,  firewire, ultra-wide scsi, 3 IDE hard drive (two
5400rpm, one 7200rpm), 1 CD-RW. With this IDE card plugged in, I have
another CD-ROM player connected. Is it too much for 300 power supply?
