Publico aquí porque estoy usando Ubuntu, pero probablemente sea un problema de hardware. Desde que compré mi nueva configuración con el procesador AMD Athlon(tm) II X4 635 y la placa base asus m4a89td pro/usb3 con ecc ram, he tartamudeado en los videos. Estaba usando ubuntu 11.10 ahora ubuntu 12.10. Al mirar syslog, descubrí que periódicamente (lo noto solo en los videos, pero sucede siempre) sucede esto:

Tengo:
- biografías actualizadas;
- probé todas las (realmente) opciones de BIOS;
- carnero cambiado;
- se cambió la fuente de alimentación y el enfriador de la CPU;
- Probé el kernel 3.8.1.
¿Qué puedo hacer ahora?
¡Por favor, ayúdame!
