Installed a second video card and the system will not boot with the card in

HP Recommended
HP Envy H-8 1520t
Microsoft Windows 10 (64-bit)

I placed a AMD 6450 graphic crd in my systems. Now when I boot I get 5beeps and then nothing. I tried to take the card out and download the driver .Iwas expecting windows to find it it didn't. I also flashed the bios and install windows 10.I brought the machine as windows 8 . I recently upgrade to 10.

@ALLIN2019, Welcome to the HP Support Community!


Make sure the card is compatible with the computer and meets the specifications for your PC.

You may check the Product Specifications here


Please note, these are the parts which are tested on your PC, If you wish to try other parts you can try it at your own discretion, HP Doesn't recommend any upgrade/downgrade of any hardware parts or software that is bundled with the product. It may affect the manufacturer's warranty and performance. 

Run a test on the hardware components of the PC


1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. Perform System Test > Extensive test. Share the result.
