I have just installed this card into my Dimension E520, along with two E209WFP monitors.  I got everything to work but when I restart the computer, it stops booting up just before Windows XP launches.  The only way to get things to work again is to restart with just the VGA monitor and go through the whole process again. 

I just want to be able to shut down my computer at night and start it up normally in the morning and live a happy life. 

Help?
