First: it's an MSI x470 carbon gaming pro motherboard. I was using my PC watching youtube, and suddenly, I lost internet connection. Me: wait, what? where is the little monitor icon on the right corner? Check everything, everything is fine. Check my adapter, what? where is my ethernet adapter? "It was this moment that I know I fucked up" I reinstalled my ethernet driver, finished, restart. so I restart, bluescreen, code: inaccessible boot device Me:? system rebooted several times and repaired itself. Not working.---> reinstall my whole windows system.---> worked ---> wait, where is my another M.2 SSD? whaaat? ---> check it with my friend's PC, it's okay. Contacted MSI service and I tried all their methods to fix it. ---> not working. OKAY, I need to send it back to my retailer to check it. It was sent today. BUT!!! I wonder, what makes this happen? I was watching and not moving it, and it disappeared. Could it be something related to electricity?? Why?? Can't figure it out. Can somebody share some info about this situation?
