My PC is a CyberPower compilation from 2003 (Yeah, it's old; I know). Anywho, my issue lies in the audio. For some strange reason, everytime I boot up, my audio is just fine. However, after a time on the computer (It's never constant), the device is no longer deteced. The Sound Controller provided by Windows tells me that I have no mixer devices, but when I check the AC'97 in the Hardware Manager, it says it's functioning properly. Help? As far as I know, my drivers are totally up-to-date. The driver says it's from 7/22/06, which is the newest one.
