1)Windows Search > Device Manager. Right-click the device, select Disable, and then re-enable it. This gives Windows a chance to take another look at configuring the gpu.

2)Remember the file location of the new gpu driver.
-Download Display Driver Uninstaller: https://www.wagnardsoft.com/
-Disconnect your internet: this will keep Windows from installing a default driver after DDU has done it's thing.
-Run DDU(requires safe mode), select to uninstall the graphics driver, then select Clean and Restart.
-Try to reinstall the new driver. You can reconnect your internet afterwards whether the install fails or not.

3)Update the motherboard's bios from HP(if possible).
That's my 2 cents.

I'm surprised you're even getting picture with that card on that old motherboard. The monitor is plugged into the gpu and not the motherboard, right?
