A little help on the clickable end of things:

(Just to make it easier for everyone to take a look at the posts, forgettythatty.)
As for the problem ... I think you can boil it down to three separate areas:
One - The BIOS
Two - A Driver (or an IRQ conflict)
Three - Incompatible Software.
This is assuming that your system is relatively modern (say, assembled with new components within the last 18 months), that you have a decent, heavy-duty PSU, and have the system is on a working surge protector or a UPS. AND ... that you are not experiencing any issues due to heat. AND ... that your hard drive(s) are intact, with no bad sectors. AND ... that you have decent memory installed, with no timing issues, and that each module is viable. (This includes the FSB speed, and any jumper settings.) Finally ... that the system doesn't harbor a virus.
Have to rule these things out, ya know.
Here's the deal. I'm running WinXP Pro on my second Rig, and I'm <i>not</i> experiencing the restart problem. I know that this is not any help to you, but it is an indicator that if the BIOS is up-to-date, that if the drivers are the latest, if there are no IRQ conflicts, and if the software installed on the system is patched ... the operating system should have only minor, typical Windows bugs that come with a new release; none of which appear to cause random rebooting. Of course, the OS must be patched (and I recommend doing this manually, instead of with the automatic Windows Update), and unnecessary Services not needed for a stand-alone system should be set on manual or disabled.
I'd really like to help you figure out the source of the problem, but I'm going to need some specifications about your system. And there will be more than one person looking at this post ... so perhaps someone else will come up with a solution, even if I'm stumped.
The more details you list, the better the chance of figuring out the problem. This is includes the BIOS type, version, and date. All internal components, with the driver versions currently installed ... including the chipset. Any third-party software you personally installed, and if it has been patched.
If you can think of what you were doing when the system began to reboot .. that would be a help. And also consider <i>when</i> it occurred ... what was the last installation you made before the problem started? Was it a program, or did you update a driver? Have you seen any error messages in the Event Viewer that might help identify the problem? Was it before or after running Windows Update? Was this an upgrade, or a clean installation? Etc, etc.
Be specific as you can, forgettythatty, and perhaps one of us can help you figure out what is going on. We'll give it the old college try, anyway.
