The Stop 0x0000007A (KERNEL_DATA_INPAGE_ERROR) indicates that the requested page of kernel data from the paging file could not be read into memory. Two DMP file report a 0xC000000E error code, two others report the 0xC000009D (STATUS_DEVICE_NOT_CONNECTED) error code: in both the cases, the disk subsystem has experienced a failure. Check your disk for errors: open a command prompt windows and run the following command chkdsk /f /r STATUS_DEVICE_NOT_CONNECTED, indicates defective or loose cabling, termination, or that the controller does not see the hard disk: verify that the computer's hardware is properly connected and that the Device Manager does not report any hardware related error.
