I had the same problem, run in compatability for windows 2000. Worked for me.
Go to c:/Program files x86(just program files for 32 bit)/steam/steamapps/common/grand theft auto iv/gta4/ right click "launchGTA4.exe" go to properties, compatability tab
and select run this program in compatability mode for "windows 2000" then save and launch it from that file.
