Hey all! This is kind of urgent as it's for a client of mine so I hope someone knows the answer. He has an Asus P4B266-C with a P4 1.8Ghz and 512MB DDR266. The system has been working fine for quite some time, but recently developed a problem. The system goes through the POST procedure fine and gets to dispalying PCI devices. However, the system halts there. It doesn't start seeking boot devices though the floppy light remains on from the seek the BIOS does. This just starting for my client suddenly two weeks ago. Yesterday, I resolved the problem by clearing the BIOS and redoing the settings. I also flashed the BIOS from 1002 to 1006. It worked for a day and now it has started doing it again. Has anyone seen this before and does anyone know what causes it or how to fix it? When his system boots, it runs fine with no instability whatsoever. However, now it isn't booting at all. Can anyone help me out?! Thanks all!
