I just put together a new computer, all new parts. Pod Racer won't run at all. I get to the start of a race, and the screen goes white, the sound continues, and the computer locks up to a hardware reset. P4 2.26/533, 512 MB PC 2700 ram, Gigabyte GA-81EXP MB, Geforce 4 Ti 4200 video with 128 MB, onboard Creative sound, onboard network, WD 80GB hard drive, TDK 48x CDRW, WinXP Home. All drivers up to date, and no problems in DXDIAG. Any thoughts? Thanks.
