Hi guys. Recently I upgraded to Haswell system. My Intel DQ87PG cannot work with Gigabyte HD 7850 GV-R785OC-2GD (rev 1.0) . The motherboard will beep twice, pause and beep twice (indicating no graphic card detected). I have tested it on Gigabyte G41-Combo and it works. I have also tested another graphic card (HD 5670 & HD 6870) on the Intel DQ87PG and they work. I have flashed both the Intel DQ87PG and the GV-R785OC-2GD to the latest bios and still nothing happen. Is there any compatibility issue between them? How to solve this?
My Intel® System Identification Utility ref: 0260 7653.
Any help would be much appreciated.
