That's the unsolved mystery of the day if the repair didn't list what was replaced if anything on the receipt itself.
If the person who serviced it restored the bios defaults and your friend had toyed around in there seeing the drive set to AHCI mode and not having it set for Native ide that could have also accounted for the Windows hanging problem.
For now however "it's a mystery"! At least it's running well for the time being anyways.
