I’ve had a rarely-used PC with a replaced motherboard, boot SSD, and data mechanical drive for two years. I recently upgraded from 64 bit Win 7 to 64 bit Win 10 with no problems. Since it was rarely used, I had only 4 GB of RAM.
I get a new user who needs it for a graduate school project and is irked by slow performance. I purchase a standard pair of 8 GB DDR3 1600 RAM chips and install them – carefully, as usual.
I attempt to boot up and it suddenly won’t recognize the SSD. I recheck all the connections, but they are secure. I have no choice but to reinstall Win 7 on the mechanical drive. Any ideas as to what killed the SSD? This is the first time it has happened – I have two other PCs with SSD boot drives with no problems.
