HELP!!!! I tried to update my graphics driver and downloaded this driver from the Nvidia website. IT started to run and I chose the clean install option. Now I just get a black screen and Windows does not load. IT goes from blue to amber (button on the bottom) as if it is going back to sleep. I know that the monitor still works as I hooked my laptop up to it and it works just fine. I tried the Windows 7 startup disk and nothing has worked. Any ideas?
