The error code KERNEL_DATA_INPAGE_ERROR STOP: 0x0000007A states that the requested page of kernel data from the paging file could not be read into memory. It appears that there are some issues with the hard disk.
Use check disk command for any errors on hard disk -
Warning: Microsoft does not recommend interrupting the CHKDSK process. Microsoft does not guarantee the integrity of the disk if the CHKDSK program is interrupted. For safety you can back up your data before using the check disk command.
Use the check disk commands as follows:
1. Click Start.
2. In search window type 'cmd' and ENTER. Right click and select 'Run as administrator'.
3. Type at the command prompt CHKDSK /P and press ENTER to scan the disk.
4. Then type CHKDSK C: /F /R and press ENTER to repair corrupt sectors, if there are any.
NOTE: The root drive has to be C: and the command may schedule a task at the system startup, if it does, then press Y to schedule a task and restart the computer to perform chkdsk.
Once chkdsk completes, boot to the desktop and then check.
