My new PC has on-board video with DVI and VGA ports (both ports can be used at the same time).
I didn't have the correct VGA to DVI adaptor on hand so I installed my spare NVIDIA GeForce GT 230 video card.
Main monitor is on the NVIDIA and the extended desktop monitor is using the on-board video card.
Every time I reboot the machine my main monitor is upside down and the other monitor is off. I have to go through and set up each monitor every time using the NVIDIA control panel and Windows 7 control panel Display settings.
