|Did you replace the video adapter or just re-do the software installation.|
Try this. Go get a fresh software/driver download for the video adapter from the manufactures site. download it to your desk top.
Uninstall any video software/drivers that show in your add/remove program from control panel. Reboot and when started the picture may be all screwy but don't worry about it. click on the downloaded file and let it install and it should clear everything up....
note.... after using add/remove and your rebooting and the picture is still ok then do not run the new driver/software files.
Instead do this:
start > rght clk. MY computer > properties > hardware tab > device manager and scroll down to the video adapter and open it by double clicking the adapter...choose the driver tab and then choose to uninstall. and then close out and reboot. upon start up then run the new downloaded file on your desktop.
Change Is Good
