If other games run just fine, it could be that GTA IV has much higher specs to follow or it could be that the game was modded... Check your game installation again whether it was modified and check it's minimum and optimal requirements.

Also check your Antivirus software or other security tools. They may be scanning GTA as you play so it may cause the game to be slow. If your AV is scanning the game, list GTA IV as a trusted application so it won't be scan.

Ok back to my previous question. Have you check with your antivirus settings? All games can be reinstall and install again, why can't yours be reinstall. Is there an error when you are reinstalling it?
