Is there something that shows up in Computer Management > Disk Management that represents what your data drive should be?
I didn't check disk management. I have to be honest, I messed around with it and made things worse so I freaked out and brought it to the computer shop.
I did make them aware that I know the trainers aren't the problem. Maybe it's a virus but I read others having page file issues.
Thank you everyone. I'm super annoyed that I freaked out but hopefully the repair guy can fix it and tell me what happened.
