I recently installed Win XP Pro on my machine at home. I had no problems at first with it. but all of a sudden after upgrading the cpu to a PIII from a PII, the system will just reboot itself on its own or if I click on a desktop icon sometimes it will do the same. Any suggestions of what is causing this would be helpful. Thanks

Upgrading the CPU will require changes made to the system jumper settings which would be specific to the motherboard

The core voltage
System bus speed

Check the motherboard manual to make sure that you have a compatible dupgrade that is supported by the motherboard,then check for the jumper settings that may need to be applied.

The PIII CPU is likely handling the ACPI calls a little bit differently than the PII did.

There is a good shutdown troubleshooting guide at www.aumha.org

3 other posabilities are;
Windows Update. XP may require some different drivers for thePIII that would not have been included in an update for teh PII.

Motherboard drivers. I would see if the mb / chipset mfg has updated drivers for XP.

BIOS update. This is also a very common issue. Often the mfg finds problems after releasingthe board that are corrected by BIOS updates.
If the mb is a genuine Intel board, Intel is prolific with BIOS updates.

Windows XP has an option to reboot itself when it encounters an error instead of displaying that dreaded "blue screen". (Was that was Microsoft's answer to those things?) Nonetheless, check to see if you have that reboot option enabled. You can turn off the reboot so you can see the full error.

Control Panel

System -Advanced

Start-up recovery

Remove the tick in "Automatically Restart"

You should now get a blue screen instead of the automatic reboot.

This could be caused by a variety of reasons including an Incompatible driver, Antivirus software, or an incompatible application. But at least if you see the error (instead of the reboot) then you'll be better prepared to troubleshoot the problem.

Good luck,

Maxwell
