Hello everyone. I have a system with Ryzen 9 7950x, 32GB 6400 mhz DDR5 ram, 1 TB primary SSD where Windows 11 and Linux installed and Gainward RTX 4080 graphics card and Asus Prime X670-P Wifi mobo. I also have 1 TB SSD and 2 TB HDD's mounted. 2-3 months ago, I started to get crashes on my both OS'es. And in time, they got frequent. I bought a brand new SSD for OS installation, after a while it started again. I cannot get any error message on Windows, since BSOD screen just stays for 2-3 seconds and system restarts. After restart, I sometimes get "no Bootable device found" error on boot stage. When the crash happens on Linux, dmesg outputs show something like whole SSD disconnected. It shows I/O messages for root partition as well. I changed primary SSD 1 month ago, errors still persist. Sent mobo to the service, no issues were found. BIOS also updated and reset. When I run PC on live Linux media, I get no issues however. What can I do else? What can cause this issue? Thanks in advance.
