Bootcamp Trouble

[Sean McCormick 0]

Hay, sorry to bother but I have a mac bootcamp related question. Obviously the solution would be to throw this computer of mine into a dark hole and burn it, however I would rather not waste the money I already put into it. Back to the point, I downloaded Arma 2 and the Operation... Flashpoint I believe. Regardless, I have what you need to run DayZ, however my bootcamped computer will not run arma 2. I get the error message "Display adapter does not support format D24S8 for X8R8G8B8" I looked around and it seems to be something involving the graphics card. I don't have the funds to get a 300+ graphics card or something along those lines, instead I was hoping I was wrong and there is an easy solution to this problem. If anyone has faced the same problem, or someone who knows the solution, i'd be grateful.

Thanks again, and I honestly hope someone can help me out here.
