Chosen Solution

My desktop computer takes forever to load. When on Google mail I get message “Something is wrong, not connected to internet” but all other devices in home work excellent. In addition when inserting a memory card or opening up any drive on the computer, it takes forever to load. When I check my RAM , I am using about 50% of my 4 Gigs Is it time to reformat or replace hard drive. I am hoping there is something particular I can perform. My antivirus and utility is Norton 360. Thanks in advance Phil

take off Norton 360 and get avg Antivirus.
