Hi, so i recently bought a new disk, 960 pro 512gb. The first time i was able to see it in windows and next i installed windows 8.1. After a couple of weeks my pc crushed (i dont know why) and when i turn my pc on it said that pc needs repair. Auto repair did nothing so i plugged in my usb to reinstall windows. I deleted every partition exept my two storage hdds. Since then i havent been able to see 960 pro anywhere. Even bios cant show me. I can only see and install windows on 850 pro.
PS. bios conf. are set to m.2.
Thanks.
