I have been having issues while on the internet for some time. Web pages seem to take a long time to fully load. When streaming video from both paid/free content websites I am not always able to get high def resolution and much of the time the play back is choppy and audio out of sync with video. Videos also seem to load really slowly for what I am used to. I have 60GB internet through Charter and frequently test at speedtest dot net. There is nothing wrong with my router...according to Arris anyways. I am hardwired into my internet connection and the ethernet cord is brand new and I have no problem streaming HD audio/video in Netflix or Amazon or Youtube etc. apps on my TV when I plug the ethernet cble directly into tv. I am only using windows firewall and antivirus. I am really confused as to why everything is so slow with this pc? Any help would be great!
