Are you saying it powers up, but won't boot into Windows?  You can get into the BIOS?  If so, it may be you have a problem with the master boot record or the boot sector.  Boot with a WinXP install CD into the command line, and type "fixboot": http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/bootcons_fixboot.mspx?mfr=true

If that doesn't fix it, you may want to try "fixmbr": http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/bootcons_fixmbr.mspx?mfr=true

Probably malware - run RKill http://www.bleepingcomputer.com/download/anti-virus/rkill to get rid of any rootkits, which will prevent booting.

Callandor - I think RKill has to be run from a windows itself, cant be run from a boot?

Callandor, RKill does have to be run under Windows, and it does not remove rootkits:

RKill runs from the DOS prompt, so it can be used with bootable media.  It doesn't remove rootkits, as marcustech mentioned, but it does shutdown malware that tries to prevent your antispyware from running.

AVG has a free rootkit remover: http://download.cnet.com/AVG-Anti-Rootkit-Free/3000-8022_4-10662685.html
