Most common reason are faulty RAM, failing HDD/SDD or broken SATA cable.

Download crystaldiskinfo and see if there are any warning/caution for your HDD/SSD. If there are any warning/caution, it might be the reason.

I don't see any problem.

Try renaming the last blk file in the blocks directory of the data dir for bitcoin core and try again.

What is the default directory for potcoin? Bitcoin and litecoin use different data dirs so it might be a hardware issue if the above doesn't resolve it.

Now it keeps crashing.

Did you same error message (Fatal LevelDB error: Corruption: block checksum mismatch) on debug.log on time when it crashed?

I'll search for "error" from top to bottom:
