|PHASE0_EXCEPTION? Some part of the HAL is looking for a debugger and the rest of Windows isn't expecting one. Either your hardware is broken to the point it shouldn't POST, your install of WinXP is corrupt, or your machine is somehow misconfigured. |
If you have access to the files on the hard drive, check your boot.ini and make sure you don't have "/break" in there somewhere. Failing that, try booting into safe mode. Failing that, verify the hardware works okay with a live Linux CD. If even the CD's failing, you have bad hardware. Check the RAM, check the CPU, check the motherboard. A bad PSU can also cause random crashes, but typically the error's different each time.
