Yes, if use FM2+ CPU, both HDMI® ports will support 4k display.

Some of the SSD hard drive might produced few years ago. So the firmware on the SSD hard drive might not support newer motherboard chipset. Please contact SSD hard driver's manufacture website to update the latest firmware. It could help for resolve the detection problem.

Yes, GAMING Z97X's on-board display port will support 4k resolution (4096x2160 @ 24 Hz / 3840x2160 @ 60 Hz).

If see the "iastor.sys" blue screen error message, then it is related to the SATA device or it's driver.

The hard drive data might formated in SATA IDE mode from previus system or motherboard.

However, Hi-Fi H87S3+ board's default SATA setting is set to AHCI mode.

So these two modes cannot compatible, then windows will give you the blue screen error during boot up.

You can go to BIOS and set SATA to [IDE mode], then it should fix the problem for you.

There are two posibility for rear I/O shield no audio output.

First, you might use front audio cable for the audio output.

Second, the audio might goes to VGA card's HDMI® port.

You might need to check these two places to let audio output work properly from rear I/O shield's audio port.

You can find RAID drivers from AMD's website here. It's contain in AMD Chipset's SATA controller driver.

Choose Manual select
Step 1:  Chipsets
Step 2:  AMD 9-series
Step 3:  All 9-series
Step 4: OS version

Yes, both Dolby HD and DTS HD MA will support by motherboard's HDMI® port.

Also it could support by add on VGA card's HDMI® port if the HDMI® is version 1.3 or higher.

However, it will need an external decoder for these two audio formats to work.

Due to AMD specification limitation, it will support only two single side memory for DDR3-1600 speed.

If you two double side memory modules, then system will lower the DDR3 speed to DDR3-1333 automatically.

If system shut down automatically, then this problem could cause by CPU over-heating.

Try go to BIOS menu by press [Delete] key when system boot up.

Then check CPU temperature is under or arround 50 degrees.

If CPU temperature is over 50 degress and going up, then this could be CPU over-heat problem.

For AMD model, try to check CPU fan locked properly to the CPU bracket.

Apply some thermal grease on the CPU die surface and use copper base CPU heatsink can reduce the chance for CPU over-heat.

For Intel model, try to check CPU fan locked properly to the 4 secure holes.

Try to refer user manual from Intel CPU for proper CPU fan installation process.

After proper CPU fan installation and apply thermal grease, system should running fine and boot up to OS.

If there is any problem, please contact local dealer or local shop for system check up.

Maybe there is something wrong with your installation.

If your motherboard is running okay with current BIOS verison, we do not recommand to update the BIOS.

Because there is a chance that update BIOS can cause BIOS data corrupt and system might not boot up properly.

If you do find compatible problem or need to support latest CPU on the market.

Update BIOS might be needed and please follow BIOS download page's pdf file or FAQ here for proper BIOS update procedure.
