HP Envy 750-114 Desktop - No Signal after upgrade

HP Recommended
HP Envy 750-114
Microsoft Windows 10 (64-bit)

I upgraded my HP Envy 750-114 Desktop with a new PSU: EVGA 550 B3, 80+ Bronze 550W, Fully Modular, EVGA ECO Mode, 5 Year Warranty, Compact 150mm Size, Pow... and a new Graphics Card: EVGA GeForce GTX 1060 GAMING, ACX 2.0 (Single Fan), 6GB GDDR5, DX12 OSD Support (PXOC) 06G-P4-6161-K....  Before I installed these I read I was supposed to diable the graphics built in to the motherboard which I did via windows and then I thought AFTER I was to update the BIOS.  Well.... now there is no signal to the monitor.  I've tried everything.... even going back to all original equipment but it appears the motherboard must be confused and isn't reading it's own graphics card either.... might be the BIOS needed updated in advance....  Is there a way to reset the motherboard without the ability to see anything on a monitor???

Hi:

 

I don't see any info on resetting the motherboard on the motherboard specs page.

 

https://support.hp.com/us-en/document/c04790427

 

The only suggestion I can offer would be to unplug the PC, press the power button to drain any residual power from the circuitry, and remove the CMOS (coin cell) battery on the motherboard.

 

Leave it out for about 15 minutes or so.

 

There are no BIOS settings to disable the onboard graphics.   You don't disable the graphics adapter in Windows.

 

What you were supposed to do was to uninstall the onboard Intel graphics adapter and driver in the device manager, shut down the PC and then install your graphics card.

 

You also probably have to go into the BIOS, enable legacy mode and disable secure boot.

 

That is normally what you have to do before installing a non-HP video card.

 

See this link from HP for the settings to change (assuming removing the battery reset the BIOS).

Thanks so much for your help!  I actually took it to a local HP technician here in town and they can't identify the issue and said I should scrap the computer.... I don't think so!!!  Is there ANY WAY to get a bootable BIOS disc?  I truly think the motherboard is confused and not able to read it's own onboard card and isn't able to boot up completely.... but I can't tell for sure of course because no one can get it to show a signal to the monitor.

 

Really could use the chance at a bootable BIOS disc if it's out there anywhere....

Hi:

 

Unfortunately the only way the BIOS can be updated is via Windows.

 

There are no BIOS DOS files that can be accessed via a bootable disk.
