Intel Core 2 Quad Q9550 Yorkfield 2.83GHz CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 ASUS EAH4870 DK/HTDI/1GD5 Radeon HD 4870 1GB 256-bit NZXT Performance Power PP800 800W ATX 12V 2.2V SLI Thermaltake SpinQ Performance Series cooler
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)

I had a problem very similar to this with 2! 1GB 4870's.
however my third worked fine so i dont know if theres any other fix but RMA
I looked at the AMD forums and they say its normal at first but it keeps going. RMA looks like to be the only solution sadly
i done an RMA on the EAH 4870 DK 1G and i got a new card, and it also does the exact same thing
