Problemas Note HP

Meu PC, no minimo uma vez por dia, trava todo e reinicia sozinho. Entretando, ao inves de entrar no Windows ele aparece com essas telas, nessa ordem:

1 - Uma tela azul, escrito em branco, com esses dizeres:

"A problem has been detected and windows has been shut down to prevent damage to your computer.

KERNEL_DATA_INPAGE_ERROR

If this is the first time you have seen this stop erros screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any windows updates you might need.

If the problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. Your computer press F8 to select Advanced StartUp Options, and then select Safe Mode.
