Use Computer Management (Control Panel/Administrative Tools) to delete all partitions. You should have 64GB of unallocated space. Create a partition using all the space, formatting it to FAT32.

If after deleting all partitions you have only 8GB of unallocated space, you have a counterfeit card. It's an 8GB card with a 64GB label.
