Well, I bought a desktop computer last year that was used, and custom built. Got it home and everything worked great, until my screen wouldnt come on anymore. So, me not knowing how to diagnose computer issues very good at this point I took it into the shop. They told me that my motherboard was bad, and it would cost about $225 to have them fix it. I will replace the board myself but I want to know if replacing it would be my best option, or am I going to have a hard time finding the right board. Or would I just be better off buying a new computer?
