I've been trying to get it to work for a few days now but no luck. I start and just get a black screen and nothing else. My Screen just says no signal. Here's the DxDiag

Please help me get it to work! I want to play the baldurs gate mod for it :/

Not sure, but it may be that you only have DX11 installed. Grab the latest version of DX9 and install that. There are some components of DX9 that are not included in DX11 and this can cause issues with older games. You can install DX9 and it won't interfere with DX11 at all. Games that require one over the other will just use the proper resources by default.

Whilst I was looking at other threads before posting this someone said Dx9.0c and I downloaded and installed. Still black screen on startup :/

Hmm, I see you have a radeon card. Have you tried a different driver for it? Perhaps an older driver version. Only other thing I can think of offhand is making sure you install the game outside Programs or Programs(x86) and run the installer as admin.

I have the game installed on my Win7 64 bit rig on a completely separate drive from my OS and it works fine. I've got an nVidia card though.

Yeah when it installs it isn't in Programs(x86) its in C: in GoG. I haven't tried running the installer as admin I'll try that. Going to reinstall and try.

Well got it to work. I updated my drivers to the latest 13.11 beta drivers and bish bash bosh it worked. So for you people out there with AMD cards make sure you update to the newest drivers.
