The PC I use is my first build, worked perfectly for a couple years now, but recently, after a power outage (which i think was caused by a transformer explosion based on the loud bang outside), Half of the time when I turn my PC on it won't recognize my boot drive, and most of the time when it does recognize it, it will fail to recognize one of the other two drives, only ocassionally will it detect all 3. I've changed the cables to different SATA ports (some which were unused before then), checked boot order on BIOS to make sure it didn't change somehow, and ran diagnostics on the drives with window's only answer being that there's nothing wrong with the drives! The PC has endured many similarly violent outages in the past without breaking a sweat, and I'm not sure about what I should do next. What else should I try in order to solve the issue? Could it be an issue with another component?
