My video card has been giving me the error "no input signal or cable disconnected" seemingly at random the past few days, but always when I turn on the computer, never had it from a reboot. I didn't pay it much attention because I had ordered a new card, which I got today. After uninstalling the old one, I put the new one in only to get the same message. Unlike my old card it never worked even after 10+ tries, so I have put the old one back in for now (gave me the error once, then worked.) The LED lights all come on and I get the normal beep, so I have no idea whats going on. The cards are AGP if that matters.
