Windows 7: Error whilst playing Minecraft

Hey guys, so recently I purchased Minecraft and am going to play it, this is the first game I played on this computer and get an immediate error:



Bad video card drivers!
-----------------------



Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.

I checked Windows Update and it only found Language Packs, any ideas?

Gamebooster says the Driver is ATI Radeon Xpress 1200 Series.

After installing the Xpress 1200 Catalyst Driver Package, the problem persists
