my nforce motherboard computer decided to stop booting today.
it would start the winxp screen and after about 5 seconds would do a real quick blue screen and reboot.

i took the drive out and put it in as a slave in my intel motherboard computer.
winxp took some time booting but then it ran a chkdsk on the slave drive.
it finished and corrected errors and everything was available on the hard drive.

so i put the drive back in the 1st box and it booted fine.

guess we need to run chkdsk from time to time to ensure that the drive doesn't have problems.
