Envy Quad AIO
Microsoft Windows 10 (64-bit)

My HP All-in-one Desktop, for no reason at all, recently started up with 4 fast beeps followed by 3 long beeps & after doing that 4-5 times goes to a black screen saying "unsupported adapter installed" & then shuts down. Can anyone help with this since there doesn't seem to be any published date for this?
