I just got a new asus P4GE-V, P4 1.8A, 256MB Mushkin PC2700 DDR (tests good with memtest), Im using my old Maxtor 13 gig hard drive (never had any problems). When I set all the BIOS speeds at normal... FSB = 266MHz, CPU = 1.8GHz, CPU external frequency =100MHz - everything runs fine. But as soon as I raise the CPU external frequency to 101MHz Windows wont load and the BIOS screen says hard drive error. Disabling UDMA didnt help. So is my hard drive maxed out? Any opinions would be greatly appreciated.
