I already did that...
Ok try some things.
1. Right click on the desktop shortcut, properies and add this on the startup command line: -autoconfig
2. Check for OS updates and install them.
3. Update DirectX.
4. Update your drivers.
5. If all these don't work, add this on the startup command line: -window -dxlevel 81 +mat_forcehardwaresync 0
6. If that don't work too, change the -dxlevel 81 to -dxlevel 70.
7. Another solution (if you haven't done that) would be to uninstall the game, clear/fix the registry with a program e.g. CCleaner and install the game again. Install it on the root folder of your HDD. E.g. C:.
If not even one of these solutions solved your problem, then you will have to try the last solution. Burn your pc. After that if the problem still exists, then suicide buddy!! lol
Looks like im going to do the last solution of burning my PC and wait for enough money to spring in for me to buy a new PC..
Thank you Valve for creating an update that doesn't work on MY PC! (You guys only converted the Update to No-steam)
