Flashed XFX 4870 1GB ZFWC "power cable not attached" and wierd blocky pattern

[jojjoj23]

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.

I also have to XFX 1GB ZWFC version E.0 card. I experience all the same problem. The power cable no connected warning and same weird sleep problem (which I didn't discover until reading this post)

Any help?

Thank you so much.

Problem is solve once I flash the ROM in post #34 in the following page

Thank you so much for everyone's contribution!
