    Iastor.sys causing crashes?

    Adam_WM

      I have an HP DV6 6100. At least once daily (sometimes more), the computer will spontaneously restart -- it will just straight up go blank screen and reboot. I cannot pin it down to any cause in particular.

       

      Using a program called WHOCRASHED, it gave me the following analysis...  Anyone have any ideas on how to fix this?
