Bsod --> kernel_data_inpage_error

hello everybody

these last days i regularly had a prob with my computer.
Computer got a Bluescreen normally when I watched film, played games etc.
And it also happened right after a restart of the computer, while the desktop was loading, it just stuck and Bluescreen appeared.

OS: Win7 (x64)

So after that I installed Windows SDK--> Debugger and Analysis tool

so after the execution of that windbg.exe i got this analysis

Code:

KERNEL_DATA_INPAGE_ERROR (7a)
The requested page of kernel data could not be read in.  Typically caused by
a bad block in the paging file or disk controller error. Also see
KERNEL_STACK_INPAGE_ERROR.
If the error status is 0xC000000E, 0xC000009C, 0xC000009D or 0xC0000185,
it means the disk subsystem has experienced a failure.
If the error status is 0xC000009A, then it means the request failed because
a filesystem failed to make forward progress.
Arguments:
Arg1: 0000000000000020, lock type that was held (value 1,2,3, or PTE address)
Arg2: ffffffffc000009d, error status (normally i/o status code)
Arg3: fffffa80074bb348, current process (virtual address for lock type 3, or PTE)
Arg4: 0000000000000000, virtual address that could not be in-paged (or PTE contents if arg1 is a PTE address)
