My computer's specs are as follows:

192MB RAM
GeForce 4 MX 440 64MB (AGP)
667MHZ Intel Celeron Processor
C-Media 6 Channel Sound Card

My problem is that no matter what the game is (mainly 3d games though) the computers runs the game really slow when sound is used. When sound is turned of or the quality is changed in the sound properties in the control panel the game runs almost 2 times faster than when it had sound. Games like Driver 1 run slow on my computer with the lowest settings. Can anyone help me?

Thanks in advance.
