I purchased a Asus STRIX B250F GAMING ATX LGA1151 Motherboard, this is a new build I have added all new parts and they are as follows, Core I7-7700 cpu, 64 gb Cosair Vengeance LPX RAM, Thermatake tough power 600 watt PSU, 1 Western Digital M.2 drive, Motherboard powers up lets out 1 beep and has a single cursor on the monitor screen, also the keyboard doesn't light up so I can't open the bios. I have switched the ram around, tried one stick as well as a simple 4 gb stick with no change, I added my new 1050ti, same problem. There are no leds showing error only on lite up is the standby power, I switched around the front panel connections, still nothing. Removed the m.2 drive and tried a 380gb western digital, nothing. I went over all connections 3 times with no change, remove the cpu and checked the pins, nothing is bent, unhooked the usb from the motherboard and still nothing. I ordered in the same board refurbished and have the same problem any ideas or something I missed?
