99 percent sure mb is faulty

problem 1

ssd's

connecting second ssd causes both ssds to go undetected, sometimes the primary ssd boots normally but the second stays undetected. It happens randomly, sometimes both ssd's function normally for a month.

all ports and several cables tested,

problem 2

ram

2x4gb 1600cl9 dual channel ram has worked fine for years.
After upgrading to 2x8gb 2400cl11, Windows takes a minute to boot and is extremely slow.
i've tried setting the mhZ to the correct speed but it doesn't make a difference, also the voltage is set at the right setting of 1.65.

Now with the old ram back in, everything is still slow, what could have changed?
I reset all bios settings to default, cleared cmos, tested different ram slots.

I have long thought that the motherboard is faulty, if you have any doubt please tell me why. Thanks

Also, are you on the latest BIOS update for your motherboard? If you're on Windows 10, see if a reinstall of the OS(after creating a bootable installer using Windows Media Creation Tools) changes the issue.< Prerequisite is that your BIOS up to date.

as for the os, the pc starts off slow before it even gets to the os booting stage, bios has a hard time loading itself. So I don't see how windows would be a problem.
