Hi, I have the problems with playing games on my windows 7. At first, i can played most of the games that can be downloaded from websites. But now, I can't play most of the games.. The error message shows that there's the problem with my graphic card, and keep asking me to change the resolution and color depth. I didn't do anything with resolution and color depth, therefore no need to do anything. I'm currently using the "Realtek High Definition Audio Driver" and I've tried to upgrade to new one. But, I got the problem with installation What kind of driver should i installed ? Any suggestion? Please Help
