Black Screen/Lock ups

[Demonhero]

I bought a copy of Amnesia from GameStop, and did an install, but every time I've tried to run it, the same thing has happened, I get a black screen, and my entire computer freezes, forcing me to reboot.

Tried a number of fixes, to no avail.

Any ideas?

Processor: AMD Athlon Dual Core
RAM: 4GB
Video Card: ATI Radeon HD 4200 Integrated

Download new drivers from ati.com and install them.

I have the most up to date driver for my card.

But I did get the game running, I just can't run it in fullscreen.
