ASROCK z87 Extreme4 Problem: Stuck on Post Screen

[Sqtran]

Hello!

Here's my build:

i5-4670k
Thermaltake 750W ATX PSU
EVGA GTX 770
G.Skill 1600 DDR3 2x4Gb (8Gb) RAM

So I built this computer two weeks ago. It's been running fine for the most part. However, when I came home today, I tried to turn on my computer, it was stuck in the Post Screen. Pressing any keys on the keyboard does nothing. I had to manually turn off the computer through the front panel power switch.

Anyway, the steps I've taken to try to resolve this issue so far has been:

- Clear CMOS switch after turning off power switch and unplugging power cable from unit.
- Reseat the RAM (slots 2 and 4)

And so far, that's it. Still having the same problem. I was wondering what I could do next?

Sigh, it was working just fine before I left to work too 🙁. Thank you and I appreciate your help.

I would assume it's RAM, motherboard or PSU. Have you tried the RAM one stick at a time?

No I haven't, but I will try it after this.

However, this morning I disconnected all of my HDDs (1 SDD, two HDDs) and turned it on, it allowed me to go to the BIOS setup screen.

Okay so I booted them up one at a time.

First with Intel 250Gb SDD. Went past POST screen and loaded up Windows.

Then I tried the WD Black by itself. Stuck on POST screen.

Then I tried the WD Blue by itself. Went past POST screen, asked for Windows to boot.

Then I tried SDD+WD Blue HDD, went past POST screen, loaded up Windows fine.

So it appears my WD Black is the problem....so what can I do to fix this?

I would suggest looking for a firmware update for the hard drive.
