Also, just a heads-up; GTA IV is terribly optimised for PC gaming, since it's a console-port. It's pretty common to have a low frame-rate, especially on a laptop. Looking at your specs, your system doesn't appear to meet the minimum specifications to run it.
I had this problem on Windows 8 (should be the same fix on 7) and finally figured it out.
1. Hit start and search for device install and click "Change device installation settings."
2. Click the box beside "No, let me choose what to do."
3. Click the box beside "Never install driver software from Windows Update."
4. Save Changes.
