Where can I buy a good computer cheap, that will support what I need?

I agree with the answer above me. If the mobo failed you should still be able to use the hard drive. Instead of buying a new computer just buy a new motherboard. If you know the model number of your old computer then do a little research about it at the company's website and find out the socket size for the CPU, the memory slot size (ddr2 667 for example). If you are confindent enough to do it yourself I suggest http://www.newegg.com./ You will only spend about $100.00 if that much.

If you are not confident enough to do it go to your local computer shop and I am sure they can do it for far less then $300.00. Save yourself some money and keep all your old stuff.

Installing a mobo is fairly easy if you can remember how the old one was setup and make the new one match it. Just keep track of what you do. Only if you are confident that this is the problem and you can do it. good luck!

Why cant you go to the local store and buy a new mother board and that way you will still have everything on your hard drive since you state that it was your mother board that took a dump and not the hard drive??

go to a local specialty computer store. they normally have good prices on dell, apple, hp and other computers
