BSOD - KERNEL_DATA_INPAGE_ERROR, STOP: 0x0000007A

Hello and welcome jimi but mate first
mate can wehave some system specs please as what you have posted gives us not that much towork with and given there are so many manufacturers of components andconfigurations that do influence what goes on within any given machine and OS.
System Info - See YourSystem Specs
The check is showing a drive problem and without knowing what you have SSD or spinner hard to go further.

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: fffff6fc80605140, lock type that was held (value 1,2,3, or PTE address)
Arg2: ffffffffc000009d, error status (normally i/o status code)
Arg3: 00000000538cf880, current process (virtual address for lock type 3, or PTE)
Arg4: fffff900c0a28c74, virtual address that could not be in-paged (or PTE contents if arg1 is a PTE address)
