First Built PC powers up but no boot screen, help

[donnyton]

Motherboard: http://www.newegg.com/product/produc...82E16813135026
Processor: Intel Core 2 Duo E6400
Power Supply: http://www.newegg.com/product/produc...82E16817170017 (575W max)
Video Card: ATI Radeon X1950 PRO 256mb
RAM: http://www.newegg.com/Product/Produc...82E16820220088 (1gb DDR2800)

When I turn the power on, the motherboard and video card lights up, and the case, PSU, video card, and heatsink fans ALL start. However, when I connect the monitor to the video card there is no display at all, not even a blank screen. CD Drives and Hard Drives do not turn on either. When I try an out of case installation the same things happens, motherboard and video card light up but no boot screen. Is this because the power supply is not powerful enough?

I have never used Logysis power supplies but I doubt it can handle that video card. You should also try and test your set up with the motherboard outside the case, you could have a short.

Strip the computer down to its core components as detailed in this thread.

If it refuses to boot then you have a defective part.

I'd replace that power supply on principle. It's a VERY low quality unit - that's why its so cheap. You need a quality ATX2 unit for that build, and the one you have is neither of those things.

I did do a setup with only the motherboard, video card, RAM, processor, and monitor: same thing, all the heatsink fans turned on, video card light turned red (not sure if it's supposed to turn red, but at least something's on) but nothing came on the monitor.

The next thing I would try is to boot without the Memory, see if you get beeps or maybe you get VGA, if you do try going into bios.
Just from previous experience ECS are very unreliable and badly made motherboards. I had 8 of them all go out on me and ended up replacing them with Asus.
I would replace that board with an Asus and get a good power supply.

I second the vote for ASUS; mine's been great.

And on the PSU: even if the one you've got isn't your problem, you're setting yourself up for failure down the road by using a low quality unit. Best case scenario it will fail, and you'll need a new one anyway. Worst case, it fails and takes some other components out with it....

I tried booting without any memory, and there's not even a beep from the motherboard. In addition, the motherboard does not seem to have any lights on, even though the video card does. Does this mean the motherboard is defective?
