    Using the ati flashing tool I flashed the XFX 4870 1GB ZFWC. When I start up a dialog shows up saying the cables are not connected, when in fact they are (I have double and triple checked). Also when I put the computer to sleep then wake it up a weird distorted blocky pattern appears and I have to restart the computer to fix the problem. Any suggestions to fixing these problems?

    power cable warning is common on newer cards.
    no fix.

    blocky patterns, never heard of it.

    sometimes its a blocky pattern, sometimes the card dosent even display anything. In both cases I have to restart the computer.
