Hi Guys, I have re-installed windows 7 recently.I have a NVIDIA geforce gt 540m pci-e graphic card and an integrated intel graphic card. The nvidia drivers installed correctly.But the on-board graphics card is taking over my pci-e card and bios setting are showing my video memory as 128mb when my nvidia has a video memory of 1gb, but the device manager said that the device was working correctly. When I try to play any game it says that the compatible video card was not detected. Any help is appreciated. Thank you.
