Hardware dying again as of last night. Tried each RAM stick individually and my two original ones seem to be the cause so far. If it dies again with the extra sticks I had in, them I'm going to assume motherboard is packing up. Already tried a spare PSU and ruled that out.

Memtest died midway at random points several times and once it tried to boot around 10 times and died at various points along the way.

I just wish there was a more reliable way to test motherboards and power supplies on the PC itself. Also, I'll be stuck with only 4GB RAM from me new sticks 😭
