Weird problem: XP hangs on shutdown..

This is on a new system I built in January. Due to some other issues (not just the one in the title of this post), I have since reformatted and reinstalled, so I have a clean system. I'm using WinXP Pro SP2 on an Intel 925XCV mobo, w/2 GB RAM, and 400 GB of system drive space on a RAID 0 volume.

Here's the problem:

I can boot up and do things on my system just fine--no crashes. The only difference is, if I leave the system on for several hours, and try to reboot or shutdown, this is what happens: WinXP goes thru the shutdown process, "Logging off", "Saving your settings", and then when it gets to the "Windows is shutting down" screen, it just hangs. Last night I left it on for an hour like this, just to see if whatever was hanging it would let go, or at least give me an error message--it didn't. I always have to power off the system w/the power button. When I restart, it acts like nothing happened.

But if I fire up the system, and do exactly the same tasks, but reboot often--say, at least once an hour--I don't get the hang on shutdown. This is the weird part.

When it hangs, I can still see the mouse cursor, and move it around the screen. I can tell the mouse driver is still loaded, by the way the mouse accelerates as I move it faster; i.e., I'm familiar w/my mouse settings. I'm not suggesting at all that the mouse drive is at fault--I've actually tried two different mice, one MS, one Logitech, not only w/their special model-specific drivers, but also w/the plain old standard WinXP driver. I also tried the mice on both the USB and PS/2 ports. I only include this info to give you an idea of where in the shutdown process it's getting hung up.

Oddly, at the hang-point, the keyboard doesn't seem to work--i.e., I can't do a CTRL-ALT-DEL to shut down/reboot.

So I wanted to get everyone's advice here, before I start going in and shutting off Services and such. Does this problem sound at all familiar?

It's happened often enough now, that I can say w/near-certainty that it is tied to the amount of time the computer is on between reboots. I.e., on a short time=ability to reboot. On a long time (3+ hours)=hangs on reboot.

I'll be very grateful for any advice, or pointers in the right direction to solve this issue.

Do you mean, does it go: on-off-on-off? Or do you mean, if it was on at shutdown, does it turn off when the system gets to the "hang" stage?

I realized that my last reply really wasn't relevant, as the NUMLOCK light turns off on system boot ( which is the way I have it set). It does not turn back on when the system goes to shut down and then hangs.

I've begun shutting off services, to see if one of them is caousing the problem, but so far, nada. This is the last major issue I'm dealing with on this, my first system build, so if anyone here has any ideas or suggestions, I'd really appreciate your help tracking down this last major gremlin.

Again, this issue seems very "time-related", in that rebooting soon after booting--i.e. < 1 hr.--allows me to reboot w/out a hang. But any longer than that, and a reboot or shutdown is almost certain to cause a hang.

I also need to rule out that it's a hardware issue. Please help. Thanks.
