Cannot get my second monitor to work!

I am connecting a second monitor to my Sony Vaio--VGN-SZ650N--by VGA.  Before upgrading from Vista to 7, it was working just fine.  After upgrading, I plug it in, screen blinks, but no display on second monitor.  It is a Dell G2210 by the way.  I tried restarting my computer with monitor connected, without it connected, and went into the display settings where you can change resolution, etc. on the different monitors, and nothing there.  Tried to "detect" monitor, still nothing.  Tried updating the driver, nothing(maybe wrong driver??).  I would love to get this problem solved as school is starting and I need to use my computer a lot, and really like having dual monitors.  Thanks

Hello Lowell, what graphics card have you got and where did you attempt to update the driver from?  Did the installer fail or did it seemingly properly install?
