Meus cpus são desligados periodicamente

Question

Eu postei aqui porque estou usando o Ubuntu, mas este é provavelmente um problema de hardware. Desde que comprei minha nova configuração com o processador AMD Athlon (tm) II X4 635 e asus m4a89td pro / usb3 motherboard com ecc ram gaguejo em vídeos. Eu estava usando o Ubuntu 11.10 agora Ubuntu 12.10. Olhando para o syslog eu descobri que periodicamente (eu noto apenas nos vídeos, mas isso acontece sempre) isso acontece:

Mar  6 23:36:42 virtual1 kernel: [28564.375548] smpboot: CPU 1 is now offline

Eu tenho:

• bios atualizados;
• tentou todas as opções (realmente) do BIOS;
• mudou o carneiro;
• alterou o cooler da psu e da cpu;
• tentou o kernel 3.8.1.

O que posso fazer agora?

Por favor me ajude!

Obrigado Mario
