Computer comes on but can't get anything but cursor

Too often when I turn computer on,MY computer will not download any programs.I have to turn off manually.and restart to get onto any programs at all.I also have problems with router getting on line.There are 2 computers on the router.I have to pull power from router and leave it off for about a minute,and then I can get online.Any suggestions?

Hi


What happens when you go into My Computer...does anything appear at all? Does the computer crash?
