Hello thanks for reading.
I have HP Pavillion XG838 - 799 Mhz, 350 MB RAM, Intel 82810 integrated graphics.
I bought a GeForce MX4000 PCI card and put it in the computer. I disabled the integrated graphics from the device manager. The computer did boot up and the drivers were successfully installed. The card worked great. I then shut down the computer and when I went to turn it on again, I got no usual confirmation beep and the screen stayed black. So, I took out the card and went back to original configuration. I re-enabled the integrated graphics. Can someone please help me? I need to know how to disable the integrated graphics ON the motherboard I think.
