I has a Acer Aspire 5536G notebook, but I'm having a problem with it. When I'm watching Youtube or playing some games (Like WolfTeam) and some other sites. The page or window would start lagging and the sounds would become very choppy, low pitched, and echoey. It's extremely annoying! I reinstalled the drivers for all my sound systems, but the problem sill persists... Any ideas? Thanks in advance and happy temping.
