"Hi, whenever I try to install a game on steam, it completely freezes my computer. I can't click anything, and after a few minutes I can't even move the mouse. This started happening about a day after I installed garrysmod and some mods for it. I completely reinstalled steam and the problem persists. What could be the problem? I'm running Windows 7 32 bit."
Posted this on steam support, still haven't gotten a response. I can't play BF2 until I get this resolved. :(
