Good day! When I turn on my PC, it will shut off for a few seconds but boots normally after. Then my screen will display a POST with no indicated errors, failures, or similar. The POST displays instead an option for setting the BIOS. Afterwards the PC will just run smoothly. I've already tried to check if the hardware have problems as I recently cleaned my PC, but the problem is still there. Is there any possible cause in this problem? I've already tried to ask some people regarding this matter and they suggest that it could be either in the memory or the CMOS. Waiting for your good responses. Thank you. :)

Specs:
Intel Core i5 4440 @ 3.10GHz
MSI GTX 970 Gaming 4G
ASUS Z87-A
HyperX Fury 16gb 1833mhz DDR3
FSP Raider 620W 80+ Silver
Samsung 850 EVO 250gb (Primary)
WD Blue 1tb
Seagate Barracuda 250gb

Everything are running at default setting.

When you Overclock and save settings, then the system shuts down and pauses for a couple of seconds. This is normal however if something is not quite right or a setting should be changed, then you would receive the message until rectified.

Yes you can clear CMOS back to default and that should fix it.
It is also true that an incorrect configuration of your DIMMs can cause this.

Well I haven't change anything in my settings other than just updating my BIOS long time ago, and my RAMs are installed properly and running in default settings. I probably try to reset CMOS and see what happens.

I've already tried clearing the CMOS but the problem still persist. I also tried testing my memory for problems but they are just in normal condition. Someone suggest that the problem could be within the BIOS but its odd for me because the only change that I did to the BIOS is updating it. Awaiting for other ideas.

Your signature indicates you have HyperX Fury at 1866MHz. You have an XMP profile that can be manually entered in Bios. Although I believe they should automatically Overclock to 1866MHz.

Default Bios setting may have your Dimm frequency set wrong. You can obtain the SPD information using CPUz in Windows where timings and voltage, Cas latency and your XMP profile are listed. The primary timings set manually using your XMP profile will make a difference in performance.

What did you test your DIMMs with.?

My bad on the original post because I probably have mistype the frequency. Anyways, I tried to check my memory through CPU-Z and they are running at 1866Mhz CL10-11-10 @1.5V which is the expected setting that they are running. I used the Windows Memory Diagnostic to test my memory for errors but I will try to test them again using memtest86 just to make sure.

Yes MemTest86+ is a much better method than from within windows.
You will have to change your boot priority to boot from the USB containing MemTest86+

How old is the CMOS battery in your system as this also may be a cause.
They only cost around $4 and available from most supermarkets. Battery type is CR2032.

I already tested my memory using memtest86 and they shows no problem at all. For the CMOS, its more than 3 years already.
