hmmm had a randomn problem recently where my ssd "bricked" randonly during a game- and was undetectable in the bios for about 15 mins before it started working again.
spoke to tech guy today and he said that it could be the drive or it could be a faulty sata port on the motherboard.

I really want to rule out my motherboard but how can I reliably test a fault that happens once very 2 weeks?
