I installed a digital camera driver.  The camera is a Sanyo VPC-T850.  When I rebooted I got the standard blue screen the following numbers.  It did not call out a file name or anything else.

Stop 0x0000007E (0xC000001D, 0xF7C748E2, 0xF7C747EC, 0xF7C744E8)

I had to turn off the USB controller in the setup screen to allow the pc to boot up.  Then I uninstalled the camera driver, but this did not help.  The only way I can boot up the PC is with the USB controller off.

What do I need to do?

Thank you.
