About a year and a half ago, I bought my current computer (a Gateway running Vista; the side says "GT5662", so I assume that is the model). I spent two or three weeks installing programs, uninstalling some of the programs it shipped with and altering settings. Now, I'm not computer savvy. I had never owned a mic prior to getting this computer (I bought the mic so playing Steam games would be easier). I had been getting complaints on the server about my mic being too loud or too soft. I now realize it was due to the low quality of my mic, and the fact that the placement was nuts. Vista came with some program (I unfortunately do not remember the name, but it had a yellow-orange icon and controlled everything audio, including mic and earphones), and I had never noticed it prior. Having only owned XP before, I assumed it was just a controlling device - something convenient so I didn't need to go anywhere else. So, I uninstalled it (assuming it was the source of my mic issues). Since then, my mic and earphones have not worked, but my speakers have continued to work. This was 18 months ago. About two months after it happened, I contacted tech support (gave up on fixing it myself) and I was told to reboot to a save prior to my problem. The save had been deleted. I cannot completely restore my computer to factory settings, as I have too much installed on it that would be loss. Can it be fixed easily?
