It's not uncommon to buy a new computer and have to update drivers. Even the High end AlienWare line that is now part of Dell more often than not needs driver updates when you get it. Sad, but true. If you are using Windows update to see if your graphics drivers are up to date, I would highly recomend checking with Dell, or better yet the vendor that made them, Nvidia, Radeon, Intel. Nvidia puts out updates several times a year for the same card. It takes Dell and other computer vendors, as well as Microsoft awhile to catch up and post it as an update as well. If you have the paper work that list the graphics in your computer, you can use that to see what the latest stable drivers are on line, or though device manager (display adapters). As I said this may not help, but its a place to start.
