The Dell Precision M90 is a Dell laptop computer with a standard video card installation. You can replace the video graphics card on your Dell Precision M90 by using a few basic tools and without too much knowledge of how computers are put together. Whether the graphics card on your M90 laptop has crashed, or you simply want to update the capabilities of your computer, replacing the graphics video card on your M90 on your own will save you money.
Power off your laptop computer and unplug it from any electrical source.
Remove the battery pack from the bottom of the computer and unscrew all the screws found at the bottom of the computer using a screwdriver. Place all the screws in a secure location so that you don’t lose them.
Flip the computer back over and pop off the keyboard section of the laptop.
Unscrew all screws under the keyboard. Disconnect the wires connecting the monitor to hardware inside and pop off the laptop case.
Locate the video graphics card. The video card will be located close to the monitor, will have been hooked up to the monitor, and will have a metal case covering it.
Unscrew all the screws holding the video card in place and remove the video card.
Put the new video card in the slots where you removed the old video card from and replace all the items you took off of the computer, exactly how they were before you took it apart.
If you aren't good at taking things apart and putting them back together exactly like you found them, then you may want to hire a professional.
