On computer startup?
If so try Safe mode (repeatively press F8 function key on Windows Startup)
Then go to Device Manager (Start-->Run-->devmgmt.msc)
Click the + sign on your Display Adaptor to expand it
Then right click on your actual Display device, and uninstall it

Go back to Normal mode (ie Restart)
Go on the web, and download the most up to date driver for your Display card (from your manufactures support page)
