Recently I updated the BIOS for my GigaByte Motherboard using Q-Flash Utility .
The update was successful but under the MB Intelligent Tweaker menu in BIOS , there's a warning says VGA Graphics card is not guaranteed to operate normally
and when I logged on into windows , the screen resolution was changed to
1024 * 768
and it was
1440 * 960 , now
1440 * 960 is not available under resoultion list .
I reinstalled the Nvidia driver but nothing changed.
