Could it be that there is something wrong with the hard disk drivers, or settings in the BIOS, causing the hard drive to be forced to run in IDE mode, SATA-compatible mode (or even PIO... is that still possible on newer computers, anyway?) instead of AHCI? (On some old mainboards, the faster mode for HDD transfers can also be called DMA-mode.)
Especially when running in PIO mode, the hard disk will be dreadfully slow, and the CPU will be greatly bogged down.
It might be worth it to check these settings, and (re)install the mainboard's drivers.
I could be very wrong here, suggesting to check stuff out that maybe isn't relevant anymore for years already... I'm a bit out of the current, mainstream hardware loop (my rig is 7 years old in a few weeks), and I've actually forgotten most hardware things dating before 2007 or so.
