PC Gamer: Nearly Dangerous
Have you tried my suggestions from earlier in the this thread:
Try this first, as 0xc0000005 errors are usually created because an unrelated issued to application that crashes at the time when they happen, issues such as drivers, memory leaks, or unexpected interrupts.The exception code 0xc0000005 indicates a memory access violation.
I have found fixes for this issue ranging from checking your RAM with Memtest86+ through to using data recovery tools and a system restore. You can get more information here.
There are 8 suggestions on that list, try as many as you feel comfortable with trying yourself, but keep in mind that some options could lead to a loss of data or may require re-installation of key software from your PC, including CoD.
