Home made computer, working good. One day turn it on and no display. Check display and cable. All good. After more checks figured motherboard bad. Buy new motherboard and replaced the old one. power up and the lights and fan comes on, but no display. I have done all kinds of things and nothing. Checked power supply and good. Disconected the h.d. cd player, and nothing. Even used another motherboard and nothing. Tried a video card in one of the slots and nothing. Anybody know what going on. I do know a thing or two of computers. Not a complete dummy. Any help will be appreciated. thankyou.....
