Try reinstalling the game and then make sure both the game and windows are patched and fully up to date.

If that doesn't work, try reinstalling your video card drivers (or upgrading them).

SOURCE: unreadable disc

It might be a problem with the disc itself. Try conventional disc cleaners and repairs. If those don't work, replace the game. If it still doesn't work, then you might need to send the console back to get it repaired. If you're still under warranty.

A common fix seems to be to have either a USB headset with a mic plugged in, or something plugged into the analog mic jack. It seems they want to force you to use a mic.

COD 2 multiplayer problem


That happens if you have a realtek audio card. Just go to your Realtek control panel, enable Mic Boost and change the settings on the sound jack for quality and it might go past the error.

I know it sound stupid but looks like its generic.

Also, try checking for newer patches

Call of duty 4 will not save on multiplayer


Do you mean that it will not save your rank? If so then it is a disk error that is very rare.

COD4 Multiplayer makes computer fans loud and hot.


When you play online games it will usually require more system resources to power. Your processor also handles the data that is being sent and received during your online session. Some code for online games have more overhead than others. I do not believe that it has anything to do with your machine, but more the software and network overhead that the multiplayer game requires. If you notice that both single and multiplayer run on seperate executables...

Single Player = C:\Program Files\Activision\Call of Duty 4 - Modern Warfare\iw3sp.exe
Multiplayer = C:\Program Files\Activision\Call of Duty 4 - Modern Warfare\iw3mp.exe

Hope this helped!
