When I try to run a game on my computer it freezes seconds after trying to load and no screen pops up from the game help im running windows 7 home premium 64 bit and im trying to load gta 4

First: Make sure you have the latest drivers for EVERYTHING then try and load it again.
Second: If that fails then open up your computer and blow out the dust from in the case.

Third: Uninstall then re-install the game. Then try to load it again

Fourth: Try running it under compatibility mode for Windows XP and as an administrator.

Finally: If all else fails then downgrade to Windows XP; it should run on that.
