Video card problem

[Angrist]

Ok when I try to start SC2, this is what I get:

The videocard is not accessible because no display drivers are installed, another 3D application has exclusive access or the machine was locked. Please close any 3D applications or games and try starting StarCraft II again. Rebooting your system may also unlock the videocard.

That is in line with what Windows tells me: the display drivers aren't being used because they gave problems.

BUT! I've reinstalled them several times... I just can't get them to work again. Where is the 'start' button?

I think you're video card is fucked. You can try older drivers, but if that doesn't work then it's probably a hardware problem.
