I'm building a unit to run Flight Simulator and have a MSI Z87 G43 motherboard with Intel I5 4690k. On first time power up no video. Monitor which I know is ok says No Signal in either VGA and HDI mode. All the fans run and the Optical Driive green light comes on. I've tried switching RAM all w/o success. I saw a compatibility issue reported on PCpartspicker re problem with some of the BIOS versions. I've ordered another CPU: Intel I5 4670k which I understand doesn't have this isue. Any ideas would be most appreciated.
