Just today my computer started having some problems and I am suspecting that it may be my memory. I have the Dimension XPS and I have had it for about a year and a half. When I click on a program the program doesn't load but when I go to processes it is definately running. I try to end the process and it doesn't go away. When I click the Icon to run it again it says it is already running. The computer is also taking 5-10 minutes to shutdown/restart. Is there something blatantly wrong that I am missing? Do I need new ram? I Just reformatted about 2 weeks ago.
