I have been super impressed with everyone's help on this site. Thanks in advanced for your help. Here is what has transpired up to this point: I wasn't getting any sound. I noticed there was no audio device in the device manager. Instead of properly looking at all the incredible info I found on this site, I went to dell's website and installed what they recommended as the audio device. It is the ADI 198x integrated audio for my dell Optiplex GX260. I installed it and during the installation the screen went blue and then went black and never came back on. What has gone wrong? and What can I do to fix it?
