Monitor flashes multiple times bofre finally turning on, HD6970

I have a Sapphire HD6970 video card in my Tower. I use it to display 3 monitors. 1 is a 55" Flat screen via HDMI, The other an NEC 24" via display port, and the last an older Samsung via DVI. For a few months now, when I turn on the computer for the first time, the older samsung monitor will flash on for a split sec [the blue on light will also come on, then go off and it will do this repeatedly for a good 5 minutes sometimes before the monitor just finally turns on. I figured the monitor was going bad. My video card ended up dying after a physical move to florida, and during the time I had the card in RMA, the onboard graphix fro m my motherboard never hd this problem. Now that I have the card back from RMA it is doing it again. I have swapped ports on the montitors and even used the HMDI fr the one flickers and nothing really changes it, [again so i suspect the monitr itself] but then why did it not do it with the onboard card for the lase 2 weeks?]

any ideas? any ways to test the monitor or the card? Furmark works fine, cards stands up to testing.

  1. Does it behave abnormally if its the only display connected to the PC?
  2. that I shall try. I haven't done much troubleshooting cause it wasn't an issue for the last few weeks, and when it first started happening I was in the process of moving out of state. SO Far I have jsut swapped cords around, and noticed that it did it with every cord on every type of port.

    I will try this next with each type of cord and display.
