Black screen

Mabey your computer is barely able to hold Combat Arms, or your computer gets too hot o.O or Reinstall CA i think its too hot.

How long have you played CA? You may have to slow pc, try upgrade or reinstall CA!

If this is started recently scan ur pc for viruses, reinstall ca. If this is a reoccuring problem get a new pc

Just like bomb says, try to clean your computer using programs like ccleaner, or get a Registry repair program

Try putting it on 800x600 16bit or 1024x(I for get) 64bit or if you have it on 1024x(I for get) 16bit make that 16 64

Put all the setting to the lowest.

If that dosnt help then it is most likely your video card.

Start>Run>dxdiag
