Game freezes for seemingly no reason

Every single round I try to play my game will at one point completely freeze and have to be force closed by task manager. This has no set time as I have played over 30 minutes into a round and not crashed but have also crashed after mere minutes.

Does it work without the mod blackopsfaf-unleashed?

@magge I'll try as soon as I can.

@magge Nope, still crashes, but I think for a different reason now.

I see no reason for a crash. Try a normal map, without any mods. If it still crashes, do the usual "reinstall-everything" approach.

Also, can you post the Windows error log about the crash.
