Aspire ATC-710-UR61 I am trying to add a GPU for multi-display - adding GPU ISSUE

Touring

Hi,

 

I am trying to add a GPU for multi-display.  I am testing with Ati HD5450 512MB for now and planning to get GTX 1050 later.  However, every time I put the card in, all display outputs become blank (black screen).   Even the previous onboard ones are blank.  I rebooted many times.  Once I remove the GPU, onboard operates as normal.  I have flashed my bios to the lastest R01.B1.   Is there a way to get it working?  Is my video card too old?

 

Specs:

ATC-710-UR61, Windows10

I5-6400

16GB Ram

M.2 250GB Sandisk

2TB Seagate SATA3

500W PSU
