So I got an around year used pc from my cousin which looks in a pretty good condition from inside

specs: http://valid.canardpc.com/5vk6p0
Graphics card: Sapphire AMD HD 7950 3GB GDDR5 Dual-X With Boost
Temp: http://i.imgur.com/R7affXl.png?1
650 Watt power supply, Corsair Liquid cooling

Now the problem I am facing is with sound, its not at all clear in nay video and audio and video are out of sync in every single video/movie I try to watch
Sound is low, and increasing the sound increases noise and not the clarity.

I have also noticed small lags/Stuttering while playing Fifa(very small but still noticeable)

So I am trying to find out,where actually is the problem?
1.Graphics card (http://gpuz.techpowerup.com/15/07/18/hg7.png)
2.Sound Card
3.Drivers issue
4.Monitor issue(http://i.imgur.com/Z9lf3Zt.png?1)
5.Display cable/Port(I am using HDMI to DVI cable as my monitor doesn't have HDMI port)
6.Any other issue?

Please help me out with the same, Any kind of help would be appreciated

Thanks :)
