I recently downloaded Windows 7 Ultimate 64x, and I've been experiencing problems with either my Graphics card, or my Monitor.
At first when I restarted my computer as soon as the computer was about to load in the login screen for Windows 7 it went black. You could see the mouse pointer, and here the music it played when it finished loading, but you could see nothing but blackness, and the only way you can access the computer is by Safe Mode, regardless of how many times you restart the computer.
Secondly, as soon as I deleted my Video Card drivers
I would be able to access the computer again, and as soon as I re-installed the drivers into my computer, and restart it, my monitor (Samsung SyncMaster 2253LW) would give me this error report "Mode not supported", and the screen resolution will not change to the suggested one my monitor supports.
I downloaded the Catalyst Control Center, and it says "ATI Product not found", so I looked in my devices, and found that the driver
was installed for my graphics. Also, I try and change my screen resolution, and it doesn't show it as "SyncMaster 2253LW", it shows it as default monitor.
I'm running DVI on my monitor.
