Get and stay on the internet, then back to the desktop ->Start the Control panel (sometimes under the start key), Display, settings, advanced, adapter, properties, driver, update driver ...(look for better driver)
This will do a net search for a better display driver for your current system. You could also navigate to your Video card's Vendor's web site and manually search for the most current one there, but your previous answer implies that finding that web site will kill you. Had that same trouble before. Who made this???
You should do a "system restore -> create a restore point" (usually under system tools somehwere...)
before you do any of this. Then if it gives you any problems, you do a "system restore -> restore my system to a previous..." use the one you just created and you should be back where you were.
