Howdy everybody - had the same problem as many on a unit running WIndows 7 - symptoms.....
1 - no display at all.
2 - a boot up screen with the motherboard splash art and ability to enter the bios.
3 - start up windows normally, safe mode, and. All the other modes to run windows and all of them bring a black screen with a cursor in the middle.
4 - unable to produce anything from this screen but move the mouse around.
5 - windows 7 installation disk out and tried to run a repair with no luck.
6 - I tried to system restore but claims there are no restores it can find.
7 - ctrl-alt-del does not produce anything
1 - Use the Windows 7 installation cd to enter the command prompt.
2 - navigate to the root os drive (usually the C drive)
3 - look for a file called 'VIDEO.EXE' It should not be there since most all the drivers are located in C:\windows\system32 folder and no drivers are located directly in the root folder from what I know. Delete this file as it is the culprit that is causing all the havoc.
4 - reboot
at most, you will either need to rerun chkdsk /r and/or sfc scannow command from the command prompt however I had to do neither. Everything starting working normally again.
Hope this helps - Best of luck to all~~!~!
