Intel CPUs "step down" their speed if they get too hot. It's possible that this is happening if it's a gradual decrease in performance during a computing session that recovers after an hour or so of switch-off.

More likely is that your hard drive has stepped down from DMA mode.

Start – Control Panel – System – Hardware (tab) – Device Manager

Select “IDE ATA/ATAPI controllers”

Select each of the primary and secondary IDE channels in turn (primary is the hard drive, secondary is the CD drive), and click on the “Advanced settings” tab when in there.

If the current transfer is PIO mode, you need to go into the registry editor to fix it. Let me know by PM if this is the case - I'm not posting public instructions on editing your registry considering the potential for royally messing up the PC.
