Weird issues with z170m oc formula

[Mythical tech]

I recently got a z170 oc formula as scrap and it boots into bios and works fine but when I try to boot into an os it reboots. I have tried two cpus and two kits of ram, reflashing the bios, downclocking the chip, running single channel. I am waiting for my electronics cleaner to arrive but if that doesn't work then I am out of ideas on what may be wrong. If anyone has encountered this problem before let me know if you were able to fix it.

Does it bluescreens when loading the OS  or as soon it accesses the drive

@Leeghoofd it goes to automatic repair for about a half second then restarts, it is a fresh install and I have tried to do a fresh install but the same thing happens.

Which OS ? Sata port ?

@Leeghoofd I tried two versions of windows 10 and all the banks of sata ports.

You already tested with another SSD/HDD and Cable?

I tried with a known good drive and cable and an m.2 drive that works on other systems.

You can try playing with csm settings in the bios ( long shot)  or boot mode maybe your windows 10 needs uefi not legacy mode?

Using the correct sata port ?
