Integrated graphics cards allow computers to display basic graphics and video but lack the processing power and dedicated video memory that is found on expansion graphics cards. Unfortunately, those who attempt to install a dedicated graphics card often find that the newly-installed card conflicts with the on-board graphics chip that is integrated into their system. It is a simple matter to bypass an integrated graphics card, though it is important that you have a dedicated graphics card ready to install once the on-board graphics card has been bypassed.
Boot up your computer, pressing the "F8" key after the initial BIOS screen in order to access the "Boot Options" menu.
Select the "Boot in Safe Mode" option from your available choices. Be patient while your operating system loads, which may take longer than normal.
Open the "Start" menu and right-click on the option that reads "Computer" or "My Computer." Select "Properties" from the bottom of the context menu that opens in order to access the "System Properties" window.
Click on the "Device Manager" option in order to open the Device Manager window. You may have to navigate to the "Advanced" tab in the System window if the Device Manager link isn't immediately apparent.
Expand the "Display Adapters" item in the Device Manager. Locate the item listed as "Integrated" or "Onboard" graphics; if you do not have a video card installed it will likely be the only item listed.
Right-click on the integrated graphics card device and select "Disable." You will be prompted as to whether you want to disable the device; click "Yes."
Click "No" when you are asked whether you wish to reboot your computer. Close all of the open windows, open the "Start" menu, then select the option to shut down the computer instead.
Unplug the computer, remove the left side panel from the computer case and install your new graphics card. When you reboot the computer it will load generic drivers for the graphics card and use it instead of the on-board graphics.
Once you have rebooted your computer using a new graphics card, install the correct drivers for the card in order to get the most usage out of it. You will need to reboot your computer one more time once the new drivers have been installed.
Wait until after the on-board graphics card has been disabled before you install a graphics card, as a conflict between the two will cause your computer to display only a black screen if you don't.
