Last night I was organising the thousands of photos I have on my PC. I nip downstairs for a drink and on my return, windows 10 is in some diagnostic mode and then reboots. From that point onwards I cannot get into windows for any period of time. After rebooting, I get into windows for at the most 2 minutes, the HD light then goes solid, and the PC freezes. Then screen goes black. When I restart, the SSD is missing from Bios. Turn machine off at the wall, turn it back on again and boots up fine, I get 1-2 minutes and rinse and repeat. Safe mode, system restore, etc. all do the same. It looks promising but after a short while, HD light stays on and everything locks up. Does that sound like a failed SSD? Its on a PC that's used about twice a week and the EVO is not that old. Feb 2016 in fact. I assumed temperature issues, due to how warm it was last night, but bios is reporting all good. I took side of case off and ramped fans up to full. Still the same. I have disconnected all the other drives, usb devices etc. Tried to use Acronis TrueImage from a USB stick and the process looks like its going to start, then locks up with a solid HD light. Which I assume would rule out a windows problem, so its the drive, or something more tricky to diagnose such as MB, RAM etc. Its frustrating that during the short period I can get in, the drive has all my files and I can navigate through windows explorer as normal. Then bang. It stops as if someone has turned a switch. Ideas or suggestions would be helpful.
