Random Reboot after login

[iTigre14]

Hello:

I have two computers with Catalina 10.15.7 and in both it has happened to me that they restart when I log in, it happens to me that there are 2 or 3 restarts and then they already work well, these are the characteristics:

Device 1:

Gigabyte GA-H170-Gaming 3
Intel Core i7 6700
16 GB Ram
RX 570 4Gb
Adata 240Gb SSD

Device 2:
Gigabyte 365 M Aorus Elite
Intel Core i7 9700k
32 Gb Ram
RX 5700 XT 8GB
Adata 240Gb SSD

In both devices, the same thing happens, two or three reboots and it is stable, in both devices I have Windows 10 on an M.2

In device 2, I have two monitors, one for hdmi and the other for displayport, but the one for displayport sometimes behaves strange, so I disconnect it, I don't know if I'm missing any configuration, also the ariplay doesn't work for me it does not display on apple tv.

Best regards

 

EDIT:

After like 8-9 reboots it already worked

I do not remember, I will do a reboot to check the bios

in the bios it was configured:
Windows 8/10 Features: Other OS

* CSM did not appear in the configuration

I made a change to
Widows 8/10 Features: Windows 8/10
CSM: Enable to Disabled

and now MacOS Catalina has not been restarted, since I started it it is working

best regards
