I tried to put a graphics card in my Envy 700-210xt, it has motherboard graphocs and I need HDMI and DVI outputs which it doesn't have. I added an ASUS 210 silent. On power up neither monitor works and the computer beeps six times. Neither monitor ever works, not singly or double, although the computer does appear to be booting.
Removing the graphics card reurns the system operation.
Suggestions?
