Continuously reboot a PC

I have a PC that a friend claims gives him an error message when its trying to boot up. The error sounds like a hard drive going bad, although the drive passes all the WD diags. It's XP Pro SP3

My question is, does anybody know of a utility, or a way, to make the PC reboot continuously? I really don't want to sit at it for an hour doing the reboot over and over again manually, but if I can get it to reboot continuously perhaps the error will rear its ugly head.

thx experts....

The question I asked was "how can I reboot my PC continuously", your answer does not address that question.
create a batch file with the following commands:

shutdown -r -t 3


and drag it to the startup folder,

An easier way is to right click on My Computer -> Properties -> Advanced -> Startup and recovery and uncheck Automatically Restart. Ask your friend to make these changes. Then, when it restarts, it should stop and display the error message. Ask your friend to copy it down for you.

I do not happen to know of a utility to continuously reboot a PC. ... Thinkpads_User

In this command, what does the 3 mean?

shutdown -r -t 3
if you execute that command at the run prompt > this will restart the computer after 3 seconds
shutdown is the command
-r >for restart (-s for shutdown)
-t for time

Reason I asked is because this worked on the PC, but it only rebooted itself 3 times, then it stayed on. Its still in the startup, and it ran OK for 3 reboots, but it never rebooted after the 3rd time. I thought the 3 meant to only do it 3 times. Any idea why it only rebooted 3 times?
thx

The drive could have an error causing some reboots.  
There could be an other hardware error as well.
The system could have been doing updates that required reboots.
The operating system could have some corruption causing reboots.

The problem is when the PC boots up, during the POST, it says "Invalid boot device", then it is manually restarted and it boots to windows fine. The PC will boot fine for the next 2-3 days, then give the same error when its turned on the forth day.

Usually when I see this error message the hard drive is on its way out, but it has passed all the WD diags, Burn-in Pro, and dozens of reboots. I cannot get it to give me the error message.

First, I assume you do not have a USB key in a USB slot, or a CD in the drive. Make sure nothing like that. If none (which I assume), then an Invalid Boot Device during POST is, in all reasonable likelihood, your hard drive failing. I would not waste even 1 minute in backing all data off that drive. It appears it could fail at any time. Drive errors like this do not necessrily neatly log themselves (as I well know), but can also fail completely at any time (as I also well know). ...
