Specs: Windows 7, Pentium 4
Computer has new motherboard, it powers up and everything sounds like it's running. Power button should be blue but it's orange. And nothing will display on the monitor.

Likely it's only the fans and drives and LEDs that are powering up while the motherboard isn't.

Does it give any beeps when you start it up?

It's a hardware problem somewhere. Why did you replace the motherboard and if it was because the previous one was bad, how sure are you it actually was bad? It could have been the power supply or a peripheral connected to the motherboard. Is the new motherboard the same as the one you replaced? If not, is it compatible with the cpu and ram--which I assume you swapped in from the old board?

With the power cord removed, temporarily disconnect the drives and remove any add-on cards not needed for an initial bootup, remove any USB devices. Then plug the cord back in and see if you at least get a posting or logo screen on the monitor. If not recheck all connections and verify the cpu and its heatsink are correctly installed.

Was told it had a bad motherboard by my local repair guy because the computer wouldn't turn on. . So I replaced it with the exact same on.

Assuming the new one is good and you got it in and connected right then I'd suspect a bad cpu or power supply but it gets expensive buying a new part on a guess that'll fix it.

Again, disconnect as many peripherals as you can and see if you get an image on the screen. If you do then one of the disconnected items must be at fault.

There's thousands of ways a computer won't work and only one way that it will. If the shop did the work you may want to take it back to them.

Suggest to disconnect all peripherals/USB/disks, remove extension (video) boards, only one ram-stick remain.
Any beeps at power-on?
Reset BIOS or remove battery for a minute?

Did all that and put in a new CPU to see if that would fix the problem, still nothing. I guess my next step is to replace the power supply, because I have replaced just about everything else in the tower.

Is this a home-built system? Or one that you purchased? If it's purchased, what the manufacturer/model?
