@The VCR King Have you tried talking with your folks, or whomever and lay out the issues your having, and potentially work out a plan to get a new machine or seriously fix this one? Basically you need the financial assistance and I'm sure if you had a good chat with them, explained the issues, and benefit to them getting involved..perhaps they would front you some $$ or work with you on a solution?
Obviously I don't know your family, but I'd bet they'd at least listen and worst case scenario give their input on what makes sense. I think your at the point where you need external help, as we can't help more than we have - and I'm sure your frustration level is peaking.
