A veces, cuando inicio mi PC, encuentro que después de la pantalla del logotipo, un _(guión bajo) parpadea y la máquina no arranca. Después de eso tengo que desconectarlo de la red eléctrica y reiniciarlo y luego funciona bien. Entonces, ¿por favor dígame qué le ha pasado a mi PC? Mis especificaciones son
Debian 7, 512 MB RAM 3 GHZ PENTIUM D PROCESSOR 256 MB GRAPHICS

Esto no tiene nada que ver con Debian, el problema que estás experimentando ocurre mucho antes de que se inicie el sistema operativo. Lo extraño es que esto sólo sucede a veces.
Una posibilidad es que tengas un disco duro defectuoso. Comprobar la salida de
sudo smartctl -a /dev/sda
Deberías ver una línea como esta:
SMART overall-health self-assessment test result: PASSED
Si su GRUB no está instalado en /dev/sda, reemplácelo /dev/sdacon el dispositivo correcto. Es posible que necesites instalar smartctl:
sudo apt-get install smartmontools

Entonces, parece que tienes problemas para leer desde el disco. Si esto comenzó recientemente, es probable que su disco esté dañado. te recomiendohaga una copia de seguridad rápidamente y compre una nueva unidad.
Antes de cambiar las unidades, asegúrese de que sus cables estén conectados correctamente (los cables del HDD) y pruebe con un cable diferente por si acaso.
