Случайные перезагрузки 20.04 LTS

В течение последних нескольких дней. мой ноутбук перезагружается случайным образом без предупреждения и через разные промежутки времени. Он просто показывает мне черный экран и перезагружает компьютер. Я не думаю, что это температура процессора, потому что ПК очень холодный.

Я выполнил тест памяти и накопителя в BIOS, и оба теста прошли успешно. Я подозреваю, что это связано с сетевой картой, потому что каждый раз, когда компьютер случайным образом перезагружается, Wi-Fi впоследствии исчезает, и он разрешает подключение только через Ethernet. Можно ли это как-то исправить?

Вот температура моего ноутбука с помощью команды датчиков:

fam15h_power-pci-00c4
Adapter: PCI adapter
power1:       12.42 mW (avg =   8.53 mW, interval =   0.01 s)
                       (crit =  15.00 W)

BAT1-acpi-0
Adapter: ACPI interface
in0:          12.10 V  
curr1:            N/A  

amdgpu-pci-0008
Adapter: PCI adapter
vddgfx:        1.55 V  
vddnb:       775.00 mV 
edge:         +51.0°C  

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +51.2°C  (high = +70.0°C)
                       (crit = +100.0°C, hyst = +99.0°C)

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +52.0°C  (crit = +226.8°C)
temp2:        +20.0°C

Мне посоветовали проверить /var/log/syslog и вот что происходит, когда она случайным образом последний раз перезагружался:
