I installed Windows 7 ultimate about 5 months ago, and was is working OK. I am having several problem with it now. I will start with my sound system. The sound system worked OK up until about a week ago, then it just stopped. Two things happened, I was trying to put a slide show on You-Tube with Scate Ignite, and adding sound to my show. While I was putting in the sound with their program it showed it was working fine, and in their upload program Dialog Box It showed a graph of the sound being uploaded into my program. So I Created the new slide show with sound, but when I tried the slide show the sound did not work. And then when I went back to using my computer the sound did not work either! I had Magic Jack on my computer, while I was tying to us the slide show I noticed that the sound was coming out of the Magic Jack system, So I disconnect the Magic Jack, and the sound still would not come out of my speaker system. And that is where I am wight now.
