Same Issue
I have a Dell Precision T7400 with a Quadro 3700 Video Card, and a SAS controller. I get through the install, can power up in safe mode, but when i boot up normally, i get the stripped down UI, like if I was in win2k server or something. When I try to click on anything I get the same message you are. Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item. Im really confused. I installed the video driver in safe mode. But i dont know what else to check. Any suggestions?? **addition** This was a fresh install.
