Windows 10: Need help installing video card

HP Pavillion P7-1110, intel i-3, 8g ram, upgraded PSU to 430w, upgraded to latest win10 (v.1903), ACER SA-230 monitor.
I recently felt the need to install a video card to speed up slow re-draws in a CAD program. I don't game.

Bought a GIGABYTE GEOFORCE GT-1030 from Amazon. Draws it's power from the PCI-E 16 pin slot'
Power on fails and locks at HP's "press esc to enter setup". wtf?
So,duh..I read the min requirements and my PSU is under powered (the reason for the PSU upgrade)

Tried changing output of card from HDMI to DVI-D with same results.
OK..I got a bad card...returned to Amazon and got the same sent to me.
Again same results.
"F" this..went to BestBuy and bought a RADEON RX560.
Again same results.
googled..some say "disable existing video in device manager"...others say "don't do that, you'll lock yourself out forever"
My question is, if I enter safe mode, disable existing driver, shut down, install Radeon again and power up, end up with same results, pull Radeon and go back to what worked prior to all this rigamarole, will Windows automatically re-start the dis-abled existing driver?
Or will POST pass on to BIOS, which will then recognize the new card?
Or will I have a boat anchor?
In my attempts I've gotten to where I can see the P.O.S.T. results and feel that's where the computer stops.
I tried installing the driver from the installation CD first before physical card install but it stops as there isn't a card installed.Some help would be greatly appreciated.

Dual video card laptops and Windows 10 upgrade

Hello,

From the description I understand that system is not switching to the fasted video card which is Radeon 7600.

I suggest you to uninstall the current video card from device manager and install Radeon 7600 manually and check if this helps.

To uninstall from device manager follow these steps:

• Press Windows Key + X key and click
  Device Manager.
• Expand ‘Display Adapters’.
  
• Right click on the video driver and click on
  uninstall.
• Now install Radeon 7600 and check.

Write us back with the status of the issue to assist you further.

Thank You.

 

Video Card Installation

Wanted to upgrade my old ATI 9000 series video card. Local electronic store suggested an
ATI Radeon X1600Pro. Installed same could only get vertical color bars on screen. Reinstalled old 9000 and all worked okay. Returned to supplier and replaced with new card,
exactly same symptoms. I feel it is unlikely that two cards are defective. Any suggestions would be appreciated.

No video after installing Windows10

Hi Adrain,

Thank you for posting in Microsoft Community.

This issue might be because of corrupted graphic drivers.

I suggest you to run the video troubleshooter and check if it helps.

• Type Troubleshooting in search and click
  Troubleshooting.
• In the left pane click on View all
• Select Video Playback.
• Follow the prompted steps to troubleshoot this issue.

I suggest you to update the graphics card drivers/display drivers from manufacturer website and check if it resolves the issue.

• Open Device Manager.
• Expand ‘Display Adapter’.
• Locate the display driver.
• Right-click on the display card listed and click on ‘Update Driver Software’

If issue still persists, I would suggest you to install the drivers in compatibility mode and check if it works.

Follow the steps provided below to install the drivers in compatibility mode:

• Right-click on the driver setup file and click on ‘properties’.
• Click on the ‘compatibility’ tab and check the box "Run this program in compatibility mode for” and select Windows operating system from the drop down.
• Click on ‘Apply’ and click ‘OK’ and run the file to install it.
