Random Reboots

[BrokenPen]

Hi, I'm having some problems with my system.

I'm running a 40GB Western Digital hard drive as my master drive, with a 120GB IBM Deskstar 120GXP slave drive.
I also have 384MB PC2100 DDR Ram, and an Athlon 1GHz chip, all on an Abit KR7A+ (not using the RAID) motherboard.
Also, Windows XP Pro.

The problem I'm having is my computer is rebooting randomly for what seems like no reason. Sometimes the reboots are hours apart, sometimes they come minutes after eachother. Its starting to drive me and friends crazy trying to figure out what's wrong. I've tried reversing the hard drives, having the IBM as master to the slave WD, but the reboots still occur.

I don't have any sort of temperature reset point set up in the BIOS, but I am wondering if a hard drive gets too hot, would it cause the system to reboot?

I'm just looking for any ideas you guys might have as to what's going on here.

Thanks in advance,
~Matthew
