Last night I downloaded Real Player and ever since it was installed my laptop has been lagging massively and my sound/video is very very sketchy. Before it was installed it was running perfectly. I did some research and found that Real Player is known for being horrible. I uninstalled it and it continued to lag so I did a system restore to before I downloaded it, and the massive lag is still there. I ran a virus scan and nothing was found. I used microsoft anti-spyware and spybot and they found nothing. Any idea's on what's going on?
