From the screenshot provided, I can see the bug check code is: 0x0000007A.
A list of bug check codes can be found on this page: Bug Check Code Reference. In this case we have: KERNEL_DATA_INPAGE_ERROR.
I can also see from the screenshot the parameters of the bugcheck, the important one here being 0xC000009C. The documentation reveals this to mean:
0xC000009C, or STATUS_DEVICE_DATA_ERROR, typically indicates bad blocks (sectors) on the hard disk.
The first thing to try therefore would be to run chkdsk againt the drive. Running with /r will find physical disk errors in the file system and attempt to recover data from any affected disk sectors.
If you can therefore boot into a command prompt, run:
This should hopefully help.
TIP: Bug check codes and parameters sometimes point you in the right direction, but typically a dump file is required. A mini-dump may be useful, depending on the issue but it may take a complete memory dump.
