Windows Does not Boot

I am Having a problem with my Windows XP SP2 system ........ it worked fine
for a long time until ..... one day it decided not to boot into the operating
system ..... the windows boot screen comes up for about 20 seconds then the
system spontaneously reboots every time in that cycle ....... it even refuses
to boot in safe mode, it does the same thing ... begins the safe mode boot
process then restarts before it finishes......Last Known Configuration
doesn't work either ...... can anyone give me an idea of how i can fix this
boot problem without having to reinstall?

You could try doing a repair from the install CD.
