I just upgraded from Vista to Windows 7 Home Premium.. Running a Dell Inspiron laptop 1545 everything seems to be running fine., Checking through the device manager, each item indicates (This Device is Working Properly)/ No yellow flags and such. Now, going to Dell's website they have a list of 12 drivers listed for this laptop. Since everything is operating ok is it necessary to install these drivers ? and if it is necessary to install them do I need to go to each device and make sure the drivers I install is meant for it ?or is there a way I am able to install drivers and let the computer decide where it goes. If this makes no sense LOL I'll eventually get it...love the learning curve..I think.... jimmy.
