Goes through BIOS but windows fails to load

[thexfactor]

No changes made to pc recently. Simply restarted and now windows xp does not load. Goes through entire bios, once it is about to display the windows welcome screen it restarts.

Installed new memory to no avail. Do I need to replace the motherboard?

PC is about 4 years old.

Thanks.

If it POSTs ok (Power On Self Test) it usually means the motherboard is ok, but the system software is not.

Using your Xp (?) CD, you could perform a Repair (you will need your Windows key for this)
