Computer won't boot

[Barbara]

The computer will boot for a short time (varies from minutes to almost an
hour)
then it just freezes.Sometimes I have to pull the power cord to get it to
reboot.
I have replaced the power supply, the memory and am running a newly
formatted
HD with only windows xp installed. I disabled all the externals. I am using
a PC Chips m981g mb with an
Intel P4 3.0 478 processor and 1 gig ddr memory.

Any ideas on what is causing this?
Thanks

Is all your hardware new? Sometime the problem might be the motherboard.
Have you try to boot your Hardisk on the other system. If your Hardisk boot
normally on that system, try to exchange all the components on your system
except your motherboard and power supply to that system, and then try to boot
it again. If your Hardisk boot properly, then your motherboard might have
problem.
