Three days ago my game freezes and then after I had problem to power it up until I replugged all power cables and reseat the RAMs. After I could played Far Cry Primal at ultra settings with no problem.

Until last night, I heard Windows was detecting a device on and off in the background. I found out it was two HDDs, they randomly appearing and disappear one of them was for storage another one the WD black was where my game files were. Next thing it freezes while playing Tomb Raider 2013 at max settings. Then I reset it and unplugged my gpu and used integrated one. It hangs at Motherboard splash screen. I could access UEFI and saw it only detected SSD but all HDD were not detected. I replugged the power cables and sata cables for all HDDs problem still persist. I did a Windows memory test. No error detected.

After a few rounds of on and off and it doesn't want to power up anymore. Sometimes fans wiggled for one second and nothing happened.

I tried to power it up this morning without GPU still using intergrated one. Saw it boot to Windows splash screen then turn off by itself and stay dead after that.

Is my mobo is faulty? Or could it be other components? Need some advise from you guys... Tks.
