Just build a new system on a M5G, but it will not startup at all, with a videcard installed. Tried a 4870x2 and a 9800gtx but I can only ocassionally get the fans to spin a bit then stop. If I pul the videocard out, the fans spin up and the post sequence seems to be going thru ok, but I don't have a HDMI connection to check it out. By default it should boot fine from either GPU or iGPU, and I have reset the cmos to no effect

Is the motherboard stuffed?
