Having a new problem where the entire PC locks up when a map is trying to load. I've tried all the following: 1. Uninstall/Reinstall game 2. Verify integrity of game cache 3. Verify integrity of tool cache for Source SDK Base 2007 4. Verified that HL2 is working 5. Uninstall/Reinstall .NET 2.0 and .NET 3.5 with SP's and updates Strangely, I was able to play one round of district....for some reason that map loaded, but then locked up the PC when the next map went to load. Have tried 5 or 6 times with other maps and can't get any to load, it just locks up the whole PC and I have to power down.
