Cyclic restart of the computer. How to decide?

Question

Iron

Good day!
Brief overview of the problem:
Partially updated my firebox with a new processor, mother, RAM. When you start a computer with an HDD connected (already with an OS) via SATA, a cyclic reboot occurs at the win10 boot stage.
Iron characteristics:
Motherboard: Asrock z390 pro4 Proc
: intel i3 - 8100 On a coffee watering can.
RAM: 16 gb hyperx.
PSU: Thermaltake toughpower 700w
HDD: WD10EXEZ Have
n't installed a video card yet.
More details:
When the system boots without disks - everything works fine: it naturally complains about the lack of an OS; goes into the BIOS fine.
When connecting an HDD with an OS, I can still go into the BIOS, set the boot priority and other little things. But after exiting the BIOS, the above problem occurs (the Windows logo is displayed, the boot animation starts).
When you try to reinstall the wines through a USB flash drive, the same thing happens anyway. It reaches the Windows logo, and then into the reboot cycle (the boot priority from the USB flash drive was set). When you try to install wines already on a new SSD, and its accompanying setting in the BIOS, exactly the same problem occurs.
It is worth mentioning that the bootable flash drive is definitely working, because Windows was already installed from it before. Yes, and on the basis of the old mother, everything was just as perfectly established on the already aforementioned HDD.
Staged loading of the system with the addition of one component each led to regular errors: 3 squeaks per RAM, etc.
I also want to note that before rebooting, the HDD somehow characteristically taps, as when it changes the position of the head.
I sin on the BP, because he is 100 years old at lunchtime, and he cracks suspiciously (there is no smell, he did not study for burnt components), and everything else also causes the case to constantly beat with current.
But it is embarrassing that he worked on the old MP. I'm not sure about the cod, like a transformer box: whether it was or not, but on the new MP it cracks. Quietly, but honestly.
PS Of the measuring instruments, only a wooden ruler. There is no opportunity to try with a working PSU.

Answer 1

Time to change BP! Urgently! That's only after that to solve the rest of the problems!

Answer 2

It is possible that when loading Windows, the load on the PSU increases abruptly, tk. the processor runs at peak power and the block is cut down from overload.
If the PSU under load makes sounds in the style of a transformer box, then it is probably in a critical mode, the nominally high and inaudible frequency of the converter operation drops so much that it moves into the audible range.
If the block is old, then the conders could dry out.
