I?�ve been fighting a new build for the last several days andhave run out of ideas.

I?�m about ready to RMA this board, but thought I?�d come herefor any final suggestions any of you might have. This is the first and onlyAsRock product I have ever owned.

The new hardware is:

AsRock Z170M Extreme 4 motherboard, Intel i5-6600K CPU, amatching pair of 4 GB sticks of Hyper X DDR4 2666 RAM from the AsRock qualifiedvendor list.

Old hardware carried over from previous build that wasworking fine last Saturday:

Antec Solo II case, no video card, Crucial SSD for OS only,3 spinning drives (WD and Samsung), Rosewill Silent Night 500 watt powersupply, Samsung DVD burner, Microsoft wired keyboard, Microsoft wired opticalmouse, Noctua NH-U12S cooler, Dell 23 inch flat panel monitor connected byDVI-D. It does not support HDMI.

Nothing at all in the PCIE slots. This is a simple,non-gaming PC.

Problem description:

It has NEVER posted. The case speaker has NEVER beeped. Iget NO screen output. For a few hours, I did get the CPU fan to spin and I didget the hard drives to spin.

For the last 24 hours, I can?�t even get the fans to spin. Noscreen output and no signs of life.

I?�ve done all the troubleshooting steps I can think of, suchas:

Pulling all parts out of the case and re-assembling on a tabletop on cardboard.

Reseating the CPU and CPU cooler.

Cleared CMOS by 2 different methods, including twice pullingthe battery for 4 hours.

Trying each RAM stick individually into all 4 slots, one ata time.

Trying RAM pairs in the recommended A2 and B2 slots.

Using 2 different power supplies, using just 4 pins on theATX 12 volt header and also using all 8 pins on the ATX 12 volt header.

None of the above steps has made any difference at all.

Does anyone have any final suggestions I can try in the next24 hours?

If not, it goes back to Newegg and I choose another brand.
