I just finished building my computer last night and upon very first boot, my 4870 starts fine then the fan stops and 3 red LEDs flash. No picture. No beep sequence. The lights go off, the fan starts again, then stops and the red lights flash again.
Both the 6 pin connectors are plugged in. Don't bother saying anything about drivers, this is very first boot!!
(Well haven't even gotten to the BIOS settings yet)
