My Old E-Machines T-4170 Exactly a year ago, my old computer quit working. I found it in the back of my closet today and I really want it to work again. When I turn on my computer and monitor, my monitor says "no signal". I hooked up my monitor to another computer and it worked perfectly fine. The computer is an E-Machines T-4170. What can I do to fix it. I'm not going to pay to send out a five year old PC.
