I feel a little silly. Yesterday I fixed the problems I was having with Windows 7. I had issues with the UI going funny and blacking out parts of the screen. Yesterday I looked into this issue. While in device manager I noticed the display I was running was a beta version of the video drivers. I also found out Dell had released a BIOS update.
I have had no problems after installing the new BIOS and the Nvidia drivers. I should have looked into this issue sooner. Now I love Windows 7 even more. The OS is awesome, much faster than Vista. I can’t wait to update my desktop once Windows 7 is released.
