I just got a brand new computer and everything was working fine. I installed Virus protection and everything so my computer should be fine. I was on Skype with some friends and I installed Skype 7.0 because I didn't want to use the pre-installed Skype. Well now I cant make a call on Skype and every time I try to watch a video its either stops after 2 seconds and sits there (Facebook) or just has a flat out black screen (YouTube). I checked my Ram and I'm not out or memory. I waited for it to buffer and nothing. What is going on?
