Well I can suggest you something. Download a program known as 3danalyzer:-
*www.filetransit.com/download.php?
Install it. then open it. select the game shortcut of black ops from inside the software.
Then select the checkbox through which you can force the game to run in windowed mode. (its in the performance option of 3d analyzer)
Then Run the game and see if it works. If it does, go under game settings>graphics and change the resolution to something lower.
This thing worked for me for many other games. Try it and see.
Please abstain from suggesting this.
3DAnalyze is only for old systems with Intel onboard graphics.
It works with my config because I have old Intel IGP but that's it. 3DAnalyze only emulates four GFX cards...and none of them are enough to run Black Ops...or any other newer game.
People having discete GPU won't need this. And techfreak's problem lies in his CPU. Its a Celeron.
Moreover, 3DAnalyze does not emulate SM 3.0 which is needed for today's games to run. So please do not suggest this or any other similar programs (like Swiftshader).
