Monitor won't turn on, No beep, Mobo not posting?

starrwsn · 04-25-2006, 07:19 PM

Hi. My monitor won't turn on but everything else is on. My motherboard must not be posting. Istill n unplugged everything except the essentials and it still would not turn on. I then tried reseting CMOS but ot luck. After trying all these things and it still not working, does this mean it is my motherboard is the hardware at fault? It is definetly not my new monitor.

Antec 480w Neo
Gigabyte K8 Triton NF3
3700+ San Diego
X800GTO HIS Turbo ICE II
Sata150 HD

This is not a new build. Brother shipped from out of state to me. It was packaged very well.

I just tried a swapped out the vid card for a 7800gt from another comp but that didn't help. Thanks

We need more info.
What motherboard,CPU,other hardware?
Is it a new build?

Okay I'll edit first post.

Make sure the case speaker is properly connected.
Disconnect the drives.
Remove the video card and the ram and see if it beeps.
It may also be a bad CMOS battery on the motherboard.
If it starts beeping,then it is probable that the motherboard and
Cpu is OK.
Add back the video and 1 stick of ram and see if it boots.
If not and you have more than 1 stick of Ram,try the other 1.
Let us know how it goes.

Speaker is fine. Removed ram and video card. No beep. Replaced battery. No beep. So does this mean either mobo or cpu?

Does the monitor have power, can you see the light on the front? What color is it and does it ever change?

Do you hear a POST beep when you power on the system?

What is your defintion of "essentials"? (Monitor/keyboard/mouse)

How did you do this? Did you remove the cmos battery?

Maybe so, but your still going to have movement inside the case. Open the case and reseat the video card.

Sorry you posted while I was typing.

No post beep could mean the memory is faulty. You must have memory installed to hear a POST beep

So far,it looks like either the motherboard or CPU.
One last thing to try.
Remove the motherbaord from the case and see if the
little brass standoffs that the motherbard mount to are in
the correct position.
They should be mounted only where they line up with the
holes in the motherboard.
If one is out of place,it can short the motherbord causing it
not to start,along with other problems.
Also,connect the speaker and other connectors required to boot it,
while it is outside the case and try to boot it.
This will indicate whether it was shorted or not.

If no memory is installed, it'll beep 3 times. Or is it 6...

starrwsn - Disconnect all power and remove your CMOS battery for about 10-20 and then try to boot again.

I'm surprised no one suggested that yet.

starrwsn · 04-26-2006, 08:22 PM

Yeah I tried to reset CMOS already. I removed battery for 30sec then I put it back in. I have 4x512mb ram. Ive tried diff ram in diff slots with only using one stick. I no its not ram, video card, or monitor because I tested with other computers. The only thing I haven't done yet was to remove the mobo to check for a short. I also havent checked the cpu. I'll have time tomorow to test cpu in another 939pin comp I have. Ill also take the mobo out and try to boot.
