Did you apply ANY mods to the game? Well of course you did by the looks of the radar.
The fix is to remove all the mods.
Are you playing with the DVD in the drive?
The San Andreas Forum is for UN-modded game questions, and problems.
All we can say here is Remove all the mods, uninstall the game and reinstall it from your DVD.
Play the game to ensure it is running properly.
Then you can install your mods ONE AT A TIME and play the game to ensure it is running Before you install the next mod.
When you get to the one that causes problems Don't Use It. Or go to the Modding forums for help with it.
