I downloaded 3dmark 05 and PCmark05... both are refusing to run on my computer. Is there a special trick you need to do in order to get it to run? I've tried Running as admin, and XP compatibility mode... nothing... it loads the splash screen, then everything goes white... and the CPU stays at 100% and doesn't go anywhere... I even tried leaving it for an hour... nothing! both programs refuse to run. I'm using the free version from the futuremark website.
