Error code, weird restart issue

Hi all,

Sometimes when I restart and update, I get a blue screen with this message:

File:\$WINDOWS.~BT\NewOS\WINDOWS\System32\winload.efi

Error code: 0xc000000f

I then push the button to force a reboot, and I can then restart without that screen.

I'm worried one day this will crash my computer or something, or at least require me to reload windows 8 and lose my files.

What's the deal?

Thanks friends!
