Hello to the community. All being well, someone can solve a problem that has been driving me crazy all week and I won't have to die in a diabetic haze of chocolate (my prefered means of suicide). I have a Dell Optiplex 330 which never gave me any problems until recently. I have no sounds whatsoever. O/S is Vista 32bit Business version. The on-board sound was okay for me, but I wanted to get better sound and start producing training videos. I Bought a Hauppauge WinTV Nova-T Freeview TV USB package, and that installed and I could watch TV and sound was fine. I was running a file recovery programme for a day or so, and when I came down the next morning, Microsoft had interrupted it with an update and reset my machine for me. After that, no sound. No TV on my PC either because it needs a sound card to work. I ordered a new ASUS Xonar D1 PCI soundcard and while waiting for it, I downloaded all the new drivers for the Dell and Hauppauge. Even some from Microsoft. Nothing made a difference. I changed a few bits in the BIOS. Still nothing. When the new soundcard turned up, I held my breath and installed the new drivers and rebooted. Still nothing. In System Driver Properties, I have a code 39 - Cannot load the device driver for this hardware. In the Control Panel in the Sound section I am told - No audio devices are installed. Against the three sound items are exclamation marked. My speaker icon is crossed through. I've tried as much as I know, but I can't get off the first base. The chocolate awaits, will I be saved?
