Left 4 Dead c++ Runtime problem

I have Left 4 Dead 1 and 2 on my desktop and it won't load up for some reason. It crashed when I see the Left 4 Dead loading screen before the main menu. It could be because of the following.

1. Steamcloud using the video setting from my laptop and applying them on the desktop.
2. Permissions need changed.
3. C++ runtime needs fixed.
4. Something else.

I have a:

AMD 64 3500+
1GB RAM
GTS 250
Windows 7 x86 Pro
latest GPU drivers

Can anyone help?

I have both Windows XP and Windows 7 in my PC. It works fine in XP but just not on Win 7.

Alright, any it suddenly stopped working in seven? I assume you've updated the drivers n' stuff?

I'm installing Mirosoft Visual Studio 2008 to see if that add the c++ files that are needed. Failing that I'll try other graphics drivers.

How much ram do you have free after loading Windows 7, XP has a much lower footprint and this could be the difference.

Win 7 has more free ram than on XP. Other games such as Grid play fine in both OS's but it just seems to be left 4 dead 1 & 2 that are the problem.
