I've got an HP nz6325 laptop (Sepron 3500+) that has suddenly started running very slowly - about 1/10th proper speed. It's not a Windows issue since if I boot from a UBCD4WIN live CD and run CPUBench, the performance figures still way down (similar to an old Pentium-90):
I've updated the BIOS to F.07 (the latest) and reset the BIOS settings to their defaults. I've also replaced the memory, but nothing has helped. There are no memory or cache settings available in the BIOS so I don't know what else to try. Any suggestions?
