I just bought a new system. Asrock H170 Pro4 ATX, Intel Core-7 6700k, EVGA GTX-980, 32 GB of ram and an EVGA 750 Watt PSU.

The first thing I noticed was what I could best describe as a "double-tap" on the power up where the board and fans would light up, go off then everything would come back on. I installed Windows 7 Enterprise easily enough but then various USB ports would go off when I would plug something new in, like a flash drive. After I was forced to use the Install CD to get the lan driver and download the USB and the newest drivers, that went away.

About two hours in the system started to hang on gaming, not even a heavy load. No BSoD and I had to reset. The event log showed "Driver ACPI returned invalid ID for a child device (5)" and " Driver ACPI returned invalid ID for a child device (1)" along with a host of other issues.

After some reading I saw this was a semi-common occurrence with these boards and I tried reverting to the microsoft audio drivers, Updated the Bios, Ran two memtests, Swapped video cards, used the on-board video (which kept cutting out). Also, The temps are fine running under 50 C.

At this point I'm not sure if I missed anything or if the board doesn't work. Anytime I've built a system in the past... It just worked.

I guess what I'm asking is if I missed something simple, and if not Can someone recommend a rock solid motherboard in the 100-150 range.

Thanks for reading.

I just finished taking everything out and putting it back in. All my connections are ok and everything is snug. I tried it with each of the 4 sticks, new, old and on-board video and I'm having the same issues. Thanks for the suggestion though, I really hate doing an RMA when I don't have to.

You think if I go to Windows 10 it will that error 56 go away? I've read in other forums that some people are having the same issues with windows ten. I really don't want to go to ten at the moment

I have an older one. It should be enough to power up the board with the graphics card out. I was getting errors without the card so I'll give that a whirl. Thanks

I figured I'd give an update. I swapped the PSU with an older, but functional one. It still did the weird double tap, I still got the ACPI child errors, and it still froze/crashed under a moderate load. I've now ruled out the graphics card, memory, overheating and PSU. At this point I'm just going to RMA the board and hope for a better one.
