I have an IP 35 Pro M/B for the past 8 months now with no issues running Vista 32. I bought my first E Sata drive from WD (MyBook 1TB). I plug the drive in and Vista sees the drive and I can copy files to and from the drive. Within a few minutes of using or not using the drive my box just locks up and boots. Vista comes back and says my NVidia 8800 driver is the cause.
I updated my IP 35 bios, Nvidia 8800 drivers and have the latest Vista updates including SP1. The box just boots randomly with no warnings. I don't even have to use the drive and it will boot. If I unplug the E Sata drive the boots stop.
The system has 4gig ram, SB X-Fi, Quad 6600 chip. No overclocking.
