I just built a system and upgraded my OS drive to a new sata drive and it works great.
I took the old 400 gb slave drive from my old computer since it had all of my games and movies on it. Well when i go to play a game off the old slave drive (which is IDE) games tend to freeze up.
The HD does not show up in bios but I can access it perfectly from windows and do not know if this is the problem or not.
It probably has a lot to do with fact the games are not technically "installed" on your new system. They are trying to run as if installed and registered on your old system. It is no wonder they crash. You need to reinstall the games. Depending on the game, you can just usually reinstall it back into the exact same directory. Most will allow you to keep your saved games and settings intact, some won't. Good luck.
