No signal I just installed a new motherboard in my computer but it is not sending signal to the monitor, we just change the power supply to see if that could be it but it is doing the same thing.

When i on my desktop it show blue screen and says no signal analog


That means that the monitor is not getting a signal from the computer. There are several possible issues involved. 1) Make sure that the computer tower is on. 2) Check that the video cable is connected to the active port on the desktop. (Computers often have video connections on the motherboard and an added video card. The motherboard connection is disabled when the video card is active. Similarly if there are several ports (VGA, DVI, HDMI, Display port) only one may be active.) 3) Try a new video cable (if possible) and one of the other video ports (again if possible). 4) Try connecting a different monitor to the computer or connecting this monitor to another computer.

Open up the computer and check if the card requires a separate power connection to the power supply. Make sure it is plugged in. Do the fans in the computer spin up?

If a second monitor doesn't work or the monitor works on another computer, then the problem is with the video adapter on the computer, the power supply or the power switch. Please add a comment with more information about the type of desktop and the current video graphics adapter (on the motherboard or separate card). I will provide additional help if possible.

(who has a computer in the company that needed a new monitor (power supply failed) a few months ago and lost the fan on the video card last week. Without the fan, the card overheated and shut down. Thus no signal to the monitor.)

Ha, no kidding!
I just had a HP Pavilion a705w come in for repair at my shop!
Small world.

Okay, let's go with your theory that the power supply is okay, and the Processor is indeed operating.

Your theory is that the GPU on the motherboard isn't working.

No Signal on the monitor means No Video Signal.

The computer isn't sending out a video signal.

(The HP Pavilion a705w comes with Integrated Graphics.

Meaning the GPU is soldered to the motherboard.
Another term for Integrated Graphics is OnBoard graphics.
On the motherBoard.

GPU stands for Graphics Processing Unit.
A GPU can be soldered to the motherboard, {Integrated Graphics}, or soldered to a dedicated graphics adapter card.

http://en.wikipedia.org/wiki/GPU

Do you have a PCI graphics card around? Still have the installation disk also?
Computer unplugged from power, and observing anti-static precautions, plug it in, screw it down to the frame.
Connect the monitor to the graphics card. Plug the computer into power.
WAIT 1 minute. Turn the computer on. You may have bad graphics because you haven't installed the drivers off of the installation CD yet, but you should have graphics.

Don't have a PCI graphics card available, or no graphics showed up on the monitor?

Okay, then humor me for a moment.
Computer unplugged from power. Anti-static precautions implemented.
Take the ram memory module/s out, and clean the gold plated contact pins with a pencil eraser.

Start at the top of the pins, and brush going down towards the bottom.

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

Use air to clean off the eraser 'dust', then reinstall the ram.
Plug into power, wait 1 minute, turn the computer on.

Still no?

Have another known, working power supply around, that is an ATX power supply, has at least 250 watts, and has the proper power cables?
I'd like you to use it for a test.

No spare power supply?
Do you have a multimeter?

It's time to check the power out of that power supply.

1) Orange insulated wires are 3.3 Volts
2) Red wires are 5 Volts
3) Yellow wires are 12 Volts
4) ANY Black wire is a Ground wire.

The Positive (Red) lead goes to the power wire, the Negative (Black) lead goes to a Ground wire.
Multimeter is set to the 50 Volt DC scale.

(Auto parts stores sell economically priced multimeter's for around $10 to $15)

Back to your statements in your added comment.

At first it could have been something as simple as the Ethernet card was bad, or the onboard Ethernet was bad.

However, it could be that the motherboard has another issue, and one by one, the motherboards features are going downhill.
No internet. Now no graphics.
Could be this,

http://www.capacitorlab.com/visible-failures/index.htm

I still think the first place to check is the power supply.
It's a cheap quality Bestec power supply.
The Electrolytic Capacitors seem to be the first components that fail in these power supply's.

However, if the computer was dirty inside, as well as the power supply, this could also make a power supply fail.

I've stated what a weak voltage power rail would do. Not enough power to turn the Processor on.
What I haven't stated is that the two main problems with a computer is,

1) The computer is dirty inside, as well as the power supply.
'Kills' power supply's and motherboards.

2) Power supply's are the second item. A pre-built computer manufacturer typically installs a cheap quality power supply.
Saves them money.

Bestec, HiPro, and Delta, are three power supply manufacturers HP uses a lot.
Cheap quality components are used inside.

If you are using an AGP Graphics Card, try a PCI VGA card. Maybe you have a faulty AGP adapter.
Assuming of course you know for sure that the Monitor and VGA cable are good.
