Por congelar quero dizer que apenas a reinicialização completa torna o sistema funcional novamente. Durante o congelamento, o cursor fica imóvel, nenhuma tecla funciona (nem AltCtrlF1-6capslock/numlock) e a música começa a repetir (tocando os últimos dois segundos). Eu tenho CPU Intel Celeron de quatro núcleos, 120 GB sda e 4 GB de RAM (durante congelamentos, não são usados mais de 1,5 Gb). O sistema está totalmente atualizado, o problema não estava aqui quando eu estava rodando o Debian. O congelamento geralmente acontece uma vez por hora, geralmente quando o navegador midori (o problema estava aqui quando eu estava executando o Firefox também) ou a fortaleza anã estão abertos. Não tenho ambiente desktop, só tenho gerenciador de janelas Openbox. O congelamento não é um fenômeno recente, o sistema continua travando desde que instalei o antergos.

Além disso, normalmente o sistema usa apenas 3-15% de cada núcleo da CPU quando ele trava, ou 100% de um dos núcleos quando a fortaleza anã está em execução.
Segunda EDIÇÃO:
Esqueci de mencionar isso antes, mas se o sistema adormecer durante o congelamento, o sistema ainda estará congelado após o login (mas o login é possível).
Terceira EDIÇÃO:
Quando uso o computador em uma superfície dura (mesa), os congelamentos ocorrem com menos frequência do que quando o uso em uma superfície macia (cama), portanto o superaquecimento pode ser parte do problema (no entanto, eles ainda ocorrem em superfícies duras e não eram). Isso estava lá quando eu tinha o Debian e já o usava em superfícies macias).
