Check this out: I found this while trying to help someone else troubleshoot. I'd be very careful overclocking with this motherboard as I've noticed many people receive buggy boards and a lot of the bugs come out when overclocking. I urge you to report any problems and any stable settings to the motherboard producer to help solve these issues. With the RGB lighting and very affordable pricing of these motherboards I for-see many people buying them in the aspirations of building a great gaming rig, but with the bugs may end up with an under-par system.

"Yeah I have similar issues as well.
Black screens, system hangs, systems locks needing power unplug (reset or power button did not work). No mouse trouble tho. They seem to be random and I cannot reproduce them.
However they happen more often when overclocking my memories or trying to run them at their rated speed and timings (both manual and DOCP settings).
I am running a Ryzen 5 1600 and corsair lpx 3000 c15. Corsair seems to be the worse choice atm for ram on this board. I hope they get fixed soon.
Another bug i saw is, when setting manual timings with docp in uefi if i set 15-17-17 (my mem's rating) the i get 16-17-17 on boot (uefi and windows). If i set 17-17-17 i get 18-17-17 again in both bios and windows. 16-17-17 works no prob. Also the settings that appear in memory timings section are mostly different to what the memory utility is saying for xmp profile.
UEFI is buggy as it stands at this point but we hope that bios programmers are active in fixing them and getting this board working as it shoud
Cheers
PS. If any one has gotten said memories stable at their rated speeds PLEASE let us know how you did it. Thanks."-mariuscc
There are four LED's connected to your motherboard that indicate where the problem lies, and it may give you clues as to whats going on with your hardware. There should be a diagram in the owners manual if they still give those with new hardware, if not there should be a diagram on the motherboard producers website.
