Determine cause of Windows 7 x86 freezing shortly after boot?

Question

Windows

Circumstances.
There are several computers with MS Windows that work properly and are used daily. However, once every six months or a year (I didn’t measure it exactly), some freeze, the circumstances of which I will now describe.
After the power is turned on, the OS boots up and the user selection and password entry fields appear. If the password is not entered immediately, but after a few minutes, the hang will occur on the inscription "Welcome". If you enter the password with the login immediately, then the desktop is displayed with all the usual shortcuts, after a few seconds it freezes. The desktop hangs, the taskbar, the clock in the tray also freezes, does not respond to pressing shortcuts. However, the mouse pointer moves, and Num Lock does respond. If you act quickly, you can have time to launch some program before freezing. When "second X" comes, its window will also hang and will not react to anything. You can, for example, have time to start the console, but it is of little use - the command will not be executed after pressing Enter, the cursor will blink, but will not respond to anything. At some point, the system may stop responding to NumLock, or it may not stop. The mouse pointer does not freeze. In this position, the system will stay for several hours. The duration, I guess, depends on the performance. For example, a system based on Intel Core I5 ​​hung in about an hour and a half, less powerful systems - in two to three hours. After this time, the system works as if nothing had happened. They work out all the clicks that were made during the hang, all programs hang, so that they are launched. I didn’t accurately measure the frequency of the appearance of such a freeze, subjectively it seems to be about six months or a year. Observed on multiple computers. Computers are in different places, connected to the Internet, through a router with a whistle or through a wired provider, also through a router. All computers have licensed Kaspersky. Windows 7 Pro is licensed everywhere, boxed or OEM almost everywhere. The problem is observed regardless of the update mode (auto/disabled). If you reboot the non-hung system with the reset button, it will hang again after logging in.
It has been noticed that freezing can occur with a high degree of probability the next day after the computer is left on for the night (forgotten to turn it off).
What I tried to do
Boot in safe mode. The system boots and does not freeze. There are no problems found on the disk. If you reboot from safe mode to normal mode, it will again hang as described at the beginning.
Clone hard drive. I did it once or twice the first time I ran into a problem, so I don't remember all the details, but it seems to help, but not always. Perhaps this is a coincidence.
Restore the system from safe mode.Helps once in a while. Why it depends is not clear. It happens that system restore does not see the restore point, then there is no way to quickly bring the system back to life, you have to wait until it sags itself.
Create a new user and log in to it . The symptoms are the same, the result is the same.
Remove antivirus . Removed from safe mode. The result is the same.

Answer 1

At me such hogwash when the screw died. A friend had a similar garbage - broken sectors on an already old screw.
There was another similar bug once, the system of the curve got up, the reinstallation helped.
Checked the plumes there everything and everything? screws?
