So I've been having problems with the Crysis2 multiplayer. Every time I try to join a match, the game would crash at the loading screen. It doesn't just crash the game, it crash my whole computer. It seem like its a really bad memory leak problem. I get a "memory allocation error" after my computer recovers from the crash. How can I fix this?

Have you a windwo like "Memory 4000000 bytes failed"? I had this in the campaign. And when I reduce my graphic or after cooling my Computer. Could I play for a long time without crashs.

Computer Information:
CPU: Phenom x4 965 (4 x 3,4 Ghz)
Grapic Card: ATI Radeon HD 4870 Series
Memory: 4 GB

That's the exact error that I got. But I don't think it is my graphic settings. I can play singleplayer perfectly on max settings. It only crashes when I try to join a match in multiplayer. That's the only time that I get that error message.
