Kernel-Power 89 (86) entradas no log do sistema Windows

Question

Anteriormente, meu PC costumava reinicializar aleatoriamente:

CRITICAL: Kernel-Power 41(63)

havia 2 arquivos antivírus AVIRA avpbb.sys e outros lançando ao mesmo tempo, portanto removi o AVIRA FREE EDITION.

Agora, as reinicializações foram interrompidas, mas há quatro entradas no Visualizador de Eventos (local) > Registro do Windows > Sistema:

Level             Source                 Event ID     Task Catagory

Information       Kernel-Processor-Power 26           4
Information       Kernel-Processor-Power 26           4

tudo ocorre ao mesmo tempo e seus detalhes são:

Kernel-Power           89           86

Minhas perguntas:

Estas entradas são normais ??

O meu processador está superaquecendo ou há algum problema com a PSU?

O ventilador da CPU no BIOS é de cerca de 1500 RPM A temperatura do processador parece estar em torno de 38-40 graus centígrados
