I was downloading a game from steam and playing another game meanwhile. Computer gave me a blue screen and I had to force close it because screen was frozen. Then my pc refused to boot. When I hold down the power button for 30 seconds SSD come back to BIOS with correct model and correct size. But moment I try to start windows it resets back to BIOS page and SSD is gone. I tried unseating it and clearing dust and making sure its probably seated back. Didn’t change anything. Also I removed cmos battery put it back and set bios default settings. No change so far? Now I dont want to format my computer because I have so many valueable documents inside. How do I fix this without losing my data?
