I have a dimension 3000 that a friend had given to them.....they are unable to get any video on it so asked me to look at it. I tried different monitor...the onboard vga connector was loose just floating so i tried a pci videocard no luck....i tried resetting cmos jumper swapping ram with known good ram...no luck. I ordered a new motherboard from dell just got it today.....installed it still no luck. The power light comes on but remains a constant amber color....the fan comes on..cd rom drives blink up....but no video. I double checked to make sure all power connectors on motherboard were correct...i also tried a known working power supply....no luck. Also the 4 troubleshooting lights on back do not light up...and i am getting no signal beeps....but the rig does power up.....just no video. If i had an extra CPU chip i would try that in it.....but my other rigs are AMD. Any suggestions would be greatly appreciated. thanks Leo
