Ok...
While I was at school, my dad decided to take matters into my own hands. He somehow got the pc running, and got chkdsk running. It apparently finished and repaired the Hard Drive on which multiple errors were found, and I am now running it perfectly fine. I'm not sure if I should do anything at all now. I haven't run any intense programs as of yet, but I soon will just to be sure that it truly is working fine.
