Have you already installed the unofficial 3.44 drivers? I was experiencing an HD issue with 2.03 drivers and winXP (see post - "clocks" on my HD") and now with these unofficial release (http://www.station-drivers.com/page/nvidia%20drv.htm#nforce) everything seem to be solved. Let me know your experience. Thx.
