First of all, I apologize for taking so long to update and respond.
Second, thank you all for the great ideas and solutions!
After I read what everyone said, I took a look online for the cables mentioned. WalMart and Target had them, but I thought it would be quicker to just buy in a store. However, I just couldn't find a store that had them in-store. I was just about to order them, but turned on my old computer and, lo and behold, it appears to have passed away in it's sleep while waiting for me to make a decision.
I'm not entirely sure it's dead. I've read a couple of other threads regarding the same problems. I know of people who've had long delays and expensive service at Geek Squad, but I went there anyway. I stood in line with three other people, then the line grew, and no one ever came out from behind the wall to help us, so I went to a smaller place. A guy there suggested I get a hard drive enclosure at another store because they didn't carry any. He didn't know my computer isn't fully booting.
So, I went back to Best Buys, but theirs was $50 and he said I shouldn't pay more than $20. I then went to Fry's (I"d never been and had been wondering what it was) and found several different ones for $15, so I bought one. Only problem now is figuring out whether I should even open it and bother trying since I think the computer has crashed.
I think I need a pute-savvy housemate. Anyone want a cheap room?
