No monitor signal from new mothermoard

Dell / XPS M1530

Specs: Microsoft Windows Vista Ultimate, 2.401 GHz / 3581 MB
I have just installed a new Intel DX58S0 motherboard
and a Pentium Quad core processor. I have an nVidia
GT220 graphics card connected as well and my
monitor to the back of that. When I turn the computer
on everything powers up, but no signal at all on the
monitor and the hard drive doesn't sound like it is
doing alot. Any suggestions as I have tried everything I
can think of?

Did you benchtest the new hardware before installing it in the case? What spec powersupply are you using? Does it have single +12V rail or multi ?


Have you connected all the power connectors to the motherboard including the PCIe supplementary molex and the SATA supplementary? The manual says to use either of those connectors or both

Hi Richard59 thanks for the response.

I am not sure what power supply that I am using, but I currently
have a 20 pin plug going into a 20 to 24 pin converter and it is
then plugged into the motherboard. Do I have to connect up all
the auxiliary power sockets on the board? Many thanks.

Yes. You cannot get any graphics without at least one of the supplementary connectors attached. Since your PSU is an old 20 pin unit I suggest you cease using it immediately. The system you are building has a reasonably high power requirement and the old ATX PSU you have is unlikely to be sufficient. I would be willing to bet you don't even have a 2X4 pin connector for the motherboard. That one is supplementary power for the CPU & chipset. Did you even read the setup instructions in the motherboard manual?

Get a decent powersupply with appropriate connectors to suit the motherboard and make sure it has a single +12V rail with 40 to 60amps . Pay more than $50 for it because if you go cheap on the PSU you risk frying the other components like motherboard & CPU etc.

Having just this second read the instructions (sorry!) I can see
that it does need the 2x4 pin cable and I don't have that. Is that
essential for me to get it working? From the symptoms I have
described, is it the power supply that would be causing the
problem? The only reason I ask is that I have spent a lot of
money on this new PC and I want to make sure it works!

Once again many thanks for your help.

"I have spent a lot of money on this new PC and I want to make sure it works!"

Then plan on spending more & getting a good modern power supply...at least $50-60.

I have just been to my local PC store and bought a new 650W
power supply. It appears to have worked, but the startup to the
BIOS seems a little slow and two of the SATA ports on the
motherboard appears not to be working. Any suggestions?
