Pros: Nice BIOS - easy to get around and nice that it works with the mouse, first mobo I've built with this

Cons: HDMI port crashes after a variable length of time but minutes not hours. First tried with Win8.1 with HDMI port connected my monitor, screen goes black a few minutes after install, then won't boot into Windows anymore. Tried Win7 with same result, tried on SSD card and HDD, no difference. Tried different Intel HD drivers, no different. Tried latest BIOS, no difference. Then tried a DVI to HDMI cable (DVI at mobo end) and it works! No clue why, might try a different HDMI cable but really can't see why that should be then problem. Maybe the HDMI port is faulty but then why stop working after a variable number of minutes working. When screen goes black incidentally, it flickers every 2 seconds between very dark grey (mobo has some output but blank) and black (no signal) Would be good to know if anyone has a clue about this or has had it and found a solution.
