this morning I received my package of another set of 4gb ram sticks. I decided I needed more so I went with this and today i put the ram and and everything went well, went to bios and saw the 16gb was all accounted for so I exited bios to restart. My pc started saying no boot device found when i was just using my pc. I tried taking out the new ram, putting sata cables in diff connectors but nothing is working. I’ve tried unplugging my hdd so the only option it ssd. Obviously i made sure the ssd was priority boot option. It’s just so weird cause the bios is telling me clearly it detects my ssd 512gb but it won’t boot at all. I’m assuming it died or something? Any ideas?
