Why does cod mw3 crash on survival when loading maps PC

the PC version of modern warfare can crash loading any map, wether it be underground on survival or crash on multiplayer. this happens because your java loader is probably not a high enough priority on your PCs java system. to fix this problem, press CONTROL + ALT + DELETE and click on task manager. hit 'Processes' then scroll down to 'java.exe' and right click on it. click 'set priority' and set it to 'high'. if you cannot find 'java.exe' you may have 'jusched.exe' or 'iexplore.exe'. Do the same process for tose files if that is what you have. this is a common problem, but i hope i helped!
