If you are having memory errors, you have to track that down before any disk checks are meaningful.
Test each card individually. If both of them work fine alone, then the memory manager is bad. It might be only the connection for a higher memory total, so you might be OK.
The problems with you disk are fairly severe, memory errors will do that. Once your memory is working properly, You have to tell it to run CHKDSK /P at the next reboot (I did not know it changed with the system language setting).
Running CHKDSK while the disk is being used cannot change the disk. You have to tell it to run when you reboot.
The problem is that you cannot trust the data on the disk, because of the past memory problems. You have to backup all of your data that is important and reinstall the OS and the programs.
Then, we can talk about CRC errors
