Game crashing - StackHash/BEX error - COD4

hey there.

I've recently bought a new mobo + processor and installed Call of Duty4(COD4)

My specs are:
System - OS Win 7 x64
CPU - I5-5670K
Motherboard - Gigabyte Z87X-D3H iZ87
Memory - MB Kingston 8 GB DDR-1333
Graphics Card - GTX 570
Hard Drives - 2 X 2 TB Hitachi
Antivirus - Bitdefender
Browser - Chrome
Just a few seconds ago, i had to manually close my cod4 through the task manager since it was not responding anymore.

Since then i cant open the game anymore.
It is giving me the following error(copy'd from the report)

I have google'd the issue and tried adding cod4 to the DEP exclusion list, but this didnt work.

Is there any1 out here who can help me with this issue ?

New update.

When i uninstall my nvidia drivers the game opens like a charm(But wont run due to not having gfx drivers )

So the problem is my driver... how to fix that?

I'd install the video drivers AND re-run the directx end user runtime and then see if it reoccurs.

Does the issue happen only only Multiplayer? What About Single Player?

The problem goes for the single and multi player.

I will do as you suggested right now
