I just upgraded my desktop computer to a 2.66ghz P4 with an Asus motherboard. About once every 10 startups, the PC freezes in the midst of its bootup, right at the Asus logo page. The only way around it is to hit the restart button, which always allows to reboot and startup again smoothly. Tell-tale sign of a system crash looming? How about any other signs that you people know of?
