?1. Shutdown switch command corrupted, so that it is going through the cycle but hanging in the back ground...you should hear the hard drives stop spinning and the fan shut off...complete silence.
?2. Shutoff button on front of computer has a physical short in it? ...?replace the button?
?3. A bios setting needs re-adjustment
?4. A software conflict where the shut down and the start up commands are sharing something...just as soon as the shut down starts, the start up gets ready to start ...there for both shut-down and startup files are corrupted
?5. Registry screw up.
?6. Evil spirits
Have you done the usual sfc /scannow routine? Defragged?
Did this start after using a regcleaner program?
Have you attempted to reinstall XP, just its own self, not deleting the rest of the files already there...this will completely rewrite the appropriate portoins of the registry.
Did malware folks tell you anything...does not sound like that sort of a problem but what do I know
How about setting the time in the BIOS between shutdown and startup, I believe there is a tweak setting to shorten or lengthen the time between shutdown and reboot, mine is set at about 20 seconds. Win98SE was quite helpful with its control over this function as I recall, or was it a dream.

Windows will reboot like that when it is commanded to do so by some operation run amok, by malware, trojans, so refer this to the malware gang.
Before we end up spinning our wheels here...check your research engine, e.g. google...for "phantom reboot" there is a ton of stuff on it...maybe your particular problem can be dealt with there

"That is a last resort, and for some people, the ones that are not that computer literate, that can be a nightmare as they lose everything except for what they backup. Unfortunately, there will always be something they forget, and sometimes something important, and it is lost forever. So we save that as last.
Some things for you to do to gather information for me:
Check Dirty Bit : Click Start, then Run, type cmd in the Open box and click "Ok". At the prompt in the Command window, type fsutil dirty query c: (This queries the drive and will tell you if it is dirty or clean)
Let me know what it reports.
Install and run Tune Up: Download and install Tune Up 2006 Trial
Click on Clean up & Repair. Run TuneUp DiskCleaner. Delete all junk files. Afterwords, return to the Main Screen.
Click on Clean up & Repair. Run TuneUp RegistryCleaner. Fix all errors. Afterwords, return to the Main Screen.
Click on Optimize & Improve. Run TuneUp RegistryDefrag, which will take a few minutes and need a reboot.
After the reboot, start Tune Up again. Click on Optimize & Improve then click on TuneUp System Optimizer. Now click on Accelerate downloads and Internet surfing to accelerate downloads, select the speed just above your actual connection speed, this requires a reboot.
After the reboot, start Tune Up again. Click on Optimize & Improve then click on TuneUp System Optimizer. In the menu to the left called "Wizards", choose System Advisor. Note some of the advice it tells you.
Use SFC /scannow to see if something's corrupt
Go to Start, Run, type sfc.exe /purgecache and press enter. When it is done purging the cache, type sfc.exe /scannow and press enter. If it asks you for your XP CD, insert it and then continue. Please let me know if it asks you for your CD.
Please report back and let me know how it goes."
I hope it helps...

While it is in the shop, ask them to give it a good cleaning...if they are going to install the thingamajig Power supply unit...yeah that's the ticket. BE CAREFUL if you are a DIY sort of fellow...you can electrocute yourself, or at least give yourself a good perm. This is something left to the techie at the shop, while you stand over him, or at least a safe distance away from him.
DIY ...read the manual well, ground both the unit and yourself well, drain the PSU before you touch it by unplugging it and then turning the switch to "on" [so I have read-do your own research to be sure]...etc.. wear rubber gloves, make out your will, warn the fire department, send the family to your mother-in-laws...
