Left 4 Dead 2 Crashes PC

After a recent video card installation, Left 4 Dead 2 (L4D2) has been crashing my PC after loading a level. This is not a crash to desktop, rather a complete system crash: screens blanks and whatever sound was playing the background starts looping.

Reinstalling the game after deleting it from Steam and removing related application data in C:\Users did not correct the issue. Completely removing all of the Steam’s games and associated application data, then reinstalling did not correct the issue.

No other game (Skyrim, ArmA II, Borderlands 2, et al.) seems to be having trouble. Other Source engine games (Portal 2, CS:GO) run with no issues.

The drivers from ATI are the most current available, the operating system is up-to-date, Steam and L4D2 are updated dynamically.

These are the system specs from dxdiag:

The symptoms sound like your GPU is overheating or its driver is malfunctioning. Check the temperature and try some older/newer drivers. –  kotekzot Jun 19 '13 at 2:39

Roll your drivers back to your previous version and see if the problem still persists. If so, it might be a recent patch for L4D2 that made it incompatible with something in your system. If possible, you could check the Event Viewer to find out what happens.

  • Go into Control Panel, and ensure "View by" is set to "Small icons" or "Large icons". "Category" won't work.
  • Click "Administrative tools", and then Even Viewer. In the left pane, expand "Windows logs" and then click "Application".
  • Give it some time to load, and find a log entry pertaining "left4dead2.exe" (or whatever L4D2 calls its executable, 'cause I'm just guessing that name there). A tip is to just invoke the problem you're experiencing, note the time down to the minute, and look for the log entry in the Event Viewer sorted by time.

Rolling back the drivers from the control panel seems to have worked. Although it was a brand new install, so I'm not sure what it rolled back to. –  Chance Jul 30 '13 at 22:30
    
Well, technically, it doesn't roll the drivers back to a previous version that was installed on your computer, but rather the previous version of the driver in general, regardless whether said version is a version you have had on your computer or not. –  Gipphe Aug 16 '13 at 19:43

A simple google search for "Left for Dead 2 Crashes Loading a Level" brought me a TON of information.

Possibilities:

 ~"Just delete the video and video defaults files. This is how to get there: 

C://programs (x86)> Steam>Steamapps>common> left 4 dead 2>left4dead2>cfg

Scroll to the bottom of that and delete video and video defaults.

 ~Turn off Multicore Rendering.

 ~Type "mat_queue_mode 0" in console.

 ~It may be a L4D2 bug. Maybe it is incompatible with your hardware

(which I HIGHLY HIGHLY doubt)

~If none of these work, Use Google! :D
