3020, Windows 7, adding a video card

averageguy2018,

To disable the onboard video follow the steps below. Also, make sure your monitor is plugged into the added video card and not the onboard video card.

START > Control Panel > System > Select the "Hardware" tab > Device Manager > Display Adapters. Right click on the listed display (common is the intel integrated graphics accelerator) and select DISABLE. Do not select uninstall.

Any Cards from Any Vendor Other than Dell will require SECURE BOOT OFF with CSM ON and Legacy Option Roms ON.

The other issue is that Nvidia will no longer offer support for 32-bit systems aka WIN 7 8 10

Thanks folks. Almost lost the computer after disabling the onboard graphics and was barely able to restore it. Will put my new card in another computer. Haven't had this difficulty with a card upgrade ever and I've done this many times before. It seems these business class computers would be more flexible not less.

Speedstep - I have a 3020 with Windows 7 Pro. Please, in an elementary fashion, advise me specifically on what steps I need to take to add a graphics card (Nvidia GT 730) to this particular machine.

In the past, I have been able to simply insert the new card and it is detected as you have just outlined above (may be the case here as well).
Alternatively on a couple of machines, I have had to go into Device Manager and disable the onboard graphics unit ahead of time.

Let me know what additional information you need from me and how exactly to find it if necessary.

Seriously, thanks a bunch.
