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: 0000000000000004, lock type that was held (value 1,2,3, or PTE address)
Arg2: 0000000000000000, error status (normally i/o status code)
Arg3: fffffa801202e100, current process (virtual address for lock type 3, or PTE)
Arg4: 000007feed80e738, virtual address that could not be in-paged (or PTE contents if arg1 is a PTE address)

We should pay attention to the disc controllers at first. The Disc Controller being used there is Intel(R) Mobile Express Chipset SATA RAID Controller.

We know that Intel RST is crash prone at its own virtue, and RAID is also problematic at its own virtue. But there is only one possible way to revert it back.

Boot into the BIOS. Disable Intel Rapid Storage. Set the SATA controller mode to AHCI. Then perform a Clean Reinstall - Factory OEM Windows 7

Then report us back how the computer is running. If still it is showing the same results, we need to concentrate on the HDD and some other hardware one by one.

That is totally your decision :)

Yes it says that some bad clusters are repaired :)
