i have 4 gigs of ram and even the simplest thing like getting online has a lag 2 it now for some reason. the laptop was really fast when i got it and has just recently started this lagging issue and i cant take it anymore. i have norton 2011 and full system scan atleast once a day before i shut down and i also have a malware scanner i use too so im thinking its not anything malicious...atleast i hope. if it is then its hiding really well. well enough to not be picked up by any scanners i have. DOES ANYONE HAVE ANY SUGGESTIONS BEFORE I FACTORY DEFAULT IT????
