Sporadic HD problem...PSU?

Worked on a machine in which the Seagate 250GB SATA HD would sporadically slow waaaay down either at boot, and/or during usage. Event Viewer showed a "bad block." Removed the drive from the machine, installed it as a slave on another machine and ran virus/antispyware scan as well as Windows (XP) and Western Digital disk diagnostics (full scan and repair options). A/V software detected/disinfected a trojan and both diagnostic utilities gave the drive a clean bill of health (including SMART). Put the drive back in original machine and it ran fine for a couple of days, then problem resurfaced.
Thinking the drive may be slowly self-destructing, I replaced it with a Seagate 320GB SATA drive and reinstalled OS and apps from scratch. No problems until I powered down the PC and powered it back up about an hour later. Slooooow boot and access times. I tried attaching the drive's SATA cable to another port (SATA 0 to SATA 1, 2, or 3) with no change.
The machine is an HP d4100y P4D (3.2GHz) machine with a Lite-On 400W PSU. Mobo is P5L-PE (945PE chipset), 2 GB (4x512) DDR2-4200, DVD burner, MSI-6600 vid card, Hauppauge 500MCE dual-tuner TV card, SB Audigy 2 ZE sound card, Seagate HD and 56K modem.
The machine ran fine for well over a year before the problem arose. My intuition tells me the following are possible suspects:
a.) PSU
b.) motherboard (south bridge?)
c.) a Windows update?
Any thoughts or suggestions are appreciated. TIA.
