Okidoky, so, I have a Powercolor Radeon 9550 se with catalyst version 4.x (I'm not 100% sure). Anyway, I got a DVD with a gaming magazine which had Catalyst version 5.6. I decided to install it, and all was fine, until a few minutes later when clicking on a certain menu link in a game of mine (TM Sunrise) caused the computer to suddenly reboot itself. I tried the game again and the same thing happened. I decided to reinstall the adapter's drivers from scratch from the cd supplied with the card, and it fixed the problem. The question is, is there a certain way to install newer drivers for graphics cards, or are the latest drivers just too advanced for the video card that I have?
