Everything was fine until I moved to clover

hey guys

So i decided it is time to move from mavericks to sierra using clover from previous tomato thingy.

Now i am fighting this for a month!

I am pretty sure I killed the motherboard already. Because sometime I won't even boot to bios (i removed pci express wifi to remove this issue)

Attached is the latest i can see. Booting usb instal or recovery is not working either.

Can someone help?

Thanks a lor
