I too am having stability issues. I just got a new Dell workstation:
Dell T5500
Quad Core E5520 2.26 GHz
6GB DDR3 ECC SDRAM 1066MHz
Quadro FX 4800 1.5GB
160GB SATA X 2 in RAID 0
Vista Business x64
I get both crashes with and without the error screen. I don't use the space pilot, so that isn't an issue.
