Hay que abrir programas hasta llegar a la parte defectuosa de la memoria, un fallo en el procesador es dificil que quede oculto.

Se deben hacer operaciones con el disco para verificar que no sea el propio disco o el chipset que controla la operaciones de E/S .

dmesg
visualiza los errores o advertencias de dispositivos.

Los errores de memoria son muy jodidos, lo mejor, lo que han comentado, dejarlo toda la noche verificando la memoria, y de paso si se cuelga se sabe que, puede ser calor o procesador.
Pasar por las Bios y mirar la temperatura del procesador y las revoluciones de los ventiladores tampoco es mala idea.


Si lo dice un MVP de MS, será cierto:

As the posts above mention, the problem is with your drivers. BSOD (Blue Screen of Death) crashes are commonly caused by bad drivers (manufacturer's code) and incorrectly blamed on the operating system. With Windows 7 being new i'm willing to bet that your manufacturer doesn't have fully working drivers.

Unfortunatly when this is the case there is little Microsoft can do as the problem is with the vendor's code. I suggest you beat down on their support lines (send them your crash information) and tell them that you are getting crashes as a result of their hardware and drivers - they should open the relevent support tickets for you.

I understand this is frustrating but as said, this isn't a Windows 7 problem - it's a video card driver problem...
