Question : Problem: HELP! No sound.  There's ONE yellow exclamation point in my Device Manager...

I've lost sound.  My speakers work just fine since I've tested them out with my mp3 player.

In my device manager there's a yellow exclamation point where it says "Game Port for Creative", in the sound, video and game controllers category.  When I right clikc on the error it says: This device cannot find enough free resources that it can use. (Code 12)  If you want to use this device, you will need to disable one of the other devices on this system.

I don't have any drivers.  What do I do?  Can anyone help me?

you should reinstall your drivers, which can be download at Creative (in your case,because I guess you have creative soundcard)

Goto the site of Creative and get your drivers at support, follow instructions and download.
