Computer shutted down after the startup button pressed, and then restarted after that shut down...
sometimes it will keep repeating that, but sometimes it will boot up normally..
sometimes I play The Division, but it will also get freeze.. (computer hangs)
also, sometimes will show up the windows blue screen after freeze. (very rare)
the boot up will be succeed when I short the jumper to reset the bios.
once I tried to boot up, it just freeze at the BIOS setup page (not the boot up screen).
I have already reinstalled the windows for few times, but also the same thing happened.
I have no idea what is this going on, and I don't want to short the jumper for each times. please help!!! I have been bored for a whole day.

Solution
Motherboard has support for DDR4 2133 MHz memory modules.

G.Skill does not guarantee memory will be able to run at specifications when combining two modules sold as singles.

You may need to compensate for using DDR4-2400MHz memory by changing BIOS settings for Memory Timing Mode as leaving them set on [Auto] may cause the PC to have trouble booting and operating normally.

Not unusual when you use bad hardware choices. (Combining modules sold as Singles, 2400MHz Memory in a motherboard that supports DDR4 2133 MHz memory modules.)
