I was having windows XP operating system installed on my desktop but as the technology changes so I have also updated myself from desktop to Acer Aspire 8920G laptop. I have installed windows 7 operating system on my new system. My system was working fine. From last few days I am facing problem with my volume slider such that it goes down automatically. I tried to restart the system so that this problem of volume slider could be fixed but couldn’t succeed. I need a solution for this problem so that I can troubleshoot this problem.
