I started having some graphics problems when playing games in Parallels 3.0. I emailed the game manufacturer, and they told me they couldn't help me because I am running a Mac (doesn't it figure?). They said it is possible that my video driver is outdated. If I am using Direct X, what can I do to update it? Thanks in advance! Attached are two pics of the graphic problems
Go to device manager => right click on display adapter => uninstall and restart your Windows Computer. When you start the Windows you will get found new hardware message click on Next and proceed with the process. This will help you to install display drivers. This should fix the issue.
