I recently reinstalled all my games in Windows 7 x64 and I changed my SATA setup to an AHCI setup before I installed 7 for better performance out of my system but now I can get the games to run. I can install them but now run them. I can play movies but not games. So how can I fix this problem I am having here. It is doing it on all of my games I have which are only a few. Those few are GTA IV and GTA San Andreas. So any and all help would be gratefull. Thanks.
