OK, assuming that the Graphics card is not the problem, there seems to be a general consensus of downgrading your Java VM to 1.4.2
That means uninstall Java, reboot, then download the JRE 1.4.2 from
Sun's Java Site
Give that a go, and report back

Edit: Also, if either of these methods do work, please post back here and say which one. Thats how forums work best
