The laptop is cut down at the start several times and the system is naughty. What to do?

Question

Windows

Good day.
The laptop (Dell Inspiron) does not start immediately, that is, by pressing the power button, I see how it turns on, then it goes out and turns on again (and this can happen several times), after turning on, it boots up before logging in and on it even get to work for 10 minutes, then the death screen crashes with the Watchdog_Violation error and then the laptop restarts and the problems already start with logging in, only now the critical process has died (or maybe just get up on a black screen), I tried recovery, but at first it didn’t work at all from for errors, but after Chkdsk it turned out, but it didn’t help, and it seems to be how it really can be in hardware, but shouldn’t the laptop then turn off randomly, and not just at the start?
In general, I want to know what I have done, what I am doing wrong, and how to solve it

Answer 1

All the best time of the day.
I was quite desperate and thinking that the problem was mechanical went to the workshop. I left the laptop and after some time they returned it to me with the words: “Your nothing is broken. But in the BIOS settings, the processing of RAID information, provided that having an ssd and hard recording in the box is best to do ACHI”, I honestly did not know this , because I’m still a young user and I don’t work with this much, I demolished Windu installed ACHI, installed the system and it works, thanks to everyone who helped me in solving the problem, I learned a lot of new things and for that I am very grateful

Answer 2

No one answers, so I'll push the theory.
It looks like a problem with the laptop's power circuits. To be more precise, check the hard drive with the Victoria program (you don’t have to run all the tests, just look at the SMART readings, if you don’t understand what’s there, then throw them here), check the RAM at least with the program built into Windows.
