goto start -> run and type in 'devmgmt.msc' without the quotes.

Open the drill down menu for Display Adapters and it should tell you what card you have. If you do have an ATI card, you could try ticking the box in Radiant Prefrences -> 2D rendering -> ATI cards with broken drivers - bug #802

Then restart Radiant and see if that helps.
