Our PC was running really slowly due to the amount of crap my son has down loaded. I've gone through and uninstalled everything I knew wasn't needed, mainly toolbars, search engines, games etc. Now it won't connect to the internet. It's not wireless so is plugged directly into the router. Could I have uninstalled something important? It's running on Windows Vista. Any other info needed?
Also I unticked everything from the start up menu, because it was taking so long to start, could that have anything to do with it?
