That's the thing, people expect if one thing isn't working other things not to work too, but no two pieces of software (unless they're almost identical) will use exactly the same resources, it's mainly DLL's that cause the issues, but can be other files. So what may effect one software may not effect others, but still be a fault with Windows, which is why one of the first things I suggest in cases where there are issues that not many others have is to reinstall the redistributables in the gameguru base folder, those contain the major DLL's required, and should fix most DLL problems.
The 6 steps I go through for trouble shooting before getting into specifics are:
1. Check the machines spec is at least somewhere between the minimum and recommended specs for the software.
2. Verify installation.
3. Check drivers (including gfx, motherboard, and sound, it's amazing how a sound driver can seemingly effect something that looks like a graphics issue and vice versa).
4. Reinstall redistributables like DX9 and Visual C++ etc.
5. Check all variations of Run Administrator and compatibility modes.
6. Check other software running at the same time for conflicts.
Once all that has been through, then I move on to specifics. It's surprising how many issues are solved before you even get to specific.
