VC Bluescreen

[RICC]

Hi everyone Im new here!
I recived my Virus Ti Desktop yesterday and have a major problem:
VC crash Cubase to desktop pretty often and
a few seconds later (5 sek-30sek) I get "Blue screen" ......
This happens moments after VC uppstart.
If I get a working start och VC witch happens sometimes it usually works without problems.


I have latest Virus TI update (2.0.3) and firmware
My Virus is connected direct to the motherboard USB port no other USB devices are connected

My system:
Asus P5b Motheboard (Bios 1102)
Intel Dualcore Conroe Processor 2.4
2gb memory 6400 Mhz
2*UAD Pci cards
Nvidia 7300 Graphic card
Yamaha 01x firewire audio mixer/card on a separate firewirecard
Cubase SX 3,1

I have:
Reistalled and tried different USB ports
Updated mainboard bios.
No other problems before I Installed the Virus Desktop and VC

UPDATED:
Dissconected my UAD Cards
Used a separate pci USB card
updated my graphic drivers
uninstalled my graphic drivers



Anyone with some Ideas?
