This configuration
The system is on the ssd with programs, and the rest on the HDD.
The first problem is that a double start periodically appears. I tried to update the BIOS, but it did not help, tell me what else I can try.
The second problem is ssd. Everything seems to work quickly, but sometimes the system freezes when dragging files and similar things.
And sometimes every few hours the icons on the desktop are updated as if

Answer 1

1 - I would look at the power settings in the motherboard. Perhaps something is written about nutrition. I would also try to throw another PSU with more power.
2 - Samsung has a utility to monitor SSD health/performance. This utility also makes some optimizations for the correct operation of Samsung SSDs. Perhaps she will prompt you to update the SSD firmware, the problem will go away
