Go to Task Mgr (the three finger salute-Ctrl-Alt-Delete)
click on "processes" and on the "explorer.exe line. Now go to "end process" and click it. Click yes on warning window.
OK, every time i get on my computer, it is running slow. So i have looked on my task manager. When i go there, the explorer.exe is taking up 100% of my ram. I have a gig of ram, so it shouldn't be that way. I would say PLEASE HELP at the end but i don't want to be a idiot!
