Internet to PC keeps dropping. Sites cannot be reached or constantly buffer. Broadband provider confirms no issues with the connection from their end. I have avg internet security, anti track, driver updater and tune up. These are always popping up. The driver updater told me there were 13 outdated drivers, which I thought might be causing the problem. It's updated 11 but is frozen on the other 2. Connection improved slightly after these updates but still keeps dropping or buffering. The PC is only 3 months old. Before I take it back to the supplier to see if there's something wrong with the PC itself, is there any advice/help you can offer? Many thanks
