Help me work from home!

Please, please help me buy a new computer. I'm not an expert graphic designer or big-name writer, but I have enough skills to make a bit of money here and there from outsourcing sites by editing images and writing web content. I can't do that without a computer that works, though.

Right now I'm working (or not, really) from an overheating, out-of-date, battery-less laptop that won't run certain graphics and video editing programs and continually shuts down on its own on a whim. I'd been dealing with that for months, but now it has taken to freezing before I run anything to begin with.

I plan on buying a (new) computer and using what money is left over to help pay for some medical expenses I have.
