I'm using Windows 7 Ultimate (64 bit) with an nVidia GeForce 8400 GS (256MB 256 PCIe) graphics card and an ASUS P5N-E SLI motherboard.
This morning I turned my computer on and it worked fine for a bit. Then it froze so I restarted, after which the screen resolution had got a lot smaller and the quality of the graphics had reduced dramatically. I tried to increase the resolution but the option was greyed out.
I tried updating the driver for my graphics card, but that didn't help.
I've looked in Device Manager, but it isn't reporting a problem with the graphics card, or any other hardware.
I've attached a screen dump to show what my display now looks like.
Please can someone suggest how to fix the problem and get my display back to normal?
