This is usually a sign your video driver needs to be installed.

For some reason my screen size always resets to 640x480 when I startup my machine. Then when I go to Control Panel and resize it, I am told I must restart my computer. So I have done that, but the setting never adjusts back to where I need it. Therefore, everything on the screen is blurry all the time. Can anyone please help???? I am completely at a loss for what to do. Thanks...
