I have a Nitro 5 AN515-53U7. This model has the empty slot for an M.2 drive. After using it for about 6months I was frustrated by how slow the stock HDD was and decided to buy an SSD and add it to the empty slot. The drive I bought was a Crucial 1tb NVMe SSD Model: CT1000P1SSD. I added the drive and 8 more gigs of RAM. Then I put the OS on to the SSD. It was a HUGE difference. My boot time went from 7.5mins (yeah it was that bad) to 22secs. I was thrilled. Then the crashing started.
The PC would blue screen to Watchdog Violation Error. Then I would try to reboot and it would say "No Bootable Device." I tried everything, fresh install of windows TWICE. Tried making sure the BIOS boot order was correct. Still it kept crashing. Weirdly though, after I would restart the PC a few times after getting the error, it would boot as normal and be completely usable for the entire day without issue. Then the next day, it would crash on startup and the cycle continued.
Yesterday it crashed and it would not boot again despite multiple reboots. When I tried to go into bios, or reinstall Windows the SSD wasn't even showing anymore. I'm now wondering if maybe the laptop didn't support this SSD or something? Either way, I can't do anything with the current drive. No idea what the problem is. If anyone can help I would really appreciate it.
