A friend brought in a Sony VAIO VGN-CR220E which he upgraded to Windows Vista Ultimate that I have been trying to fix to no avail. The system boots fine (at least appears to) and displays windows login screen. Once you enter appropriate credentials, the system goes to a black screen with only mouse cursor which you can move around with mouse but can't see anything else.
Tried seeing if it was contrast. Hooked up an external monitor, but it didn't recognize it. Tried a number of recovery options and diagnostic tests for harddrive, memory, etc. and nothing has worked.
Before giving up and reloading the operating system, just wondering if one of you wise experts has a fix or some guidance.
