My monitor and CD drives aren't rsponding.

Specs: Windows xp, AMD ATHLON 64 3000
System is 7 yr old gamer w/AMD Athlon 64, Processor Model AMD 3000+. I put in a new power supply and video card. Fans work, gaming lights work but the monitor does not and the cd drives (2) do not open so presume there's no power reaching them or the monitor. Power supply is an Okia "Switcher", 550 watts total. All but the 4 pin motherboard connector seem to be connected properly as they fit in a kind of domino sequence for peripherals as does the main 20-pin connector I cannot find a 4-pin slot on this motherboard.
I replaced the Okia with a Coolmax but it didn't even power up the lights.
I have 2 GB Ram and 200 GB hd capacity

What are the reasons for a power supply change?
I guess u bought this unit right?

We need to know system specifications.

This is my son's computer. It has not been used for several years. So, frankly I don't recall why a new power supply was put in.
- A new video card was also installed at the same time. I think it was to be an upgrade. The card is 128 mb, agp, eGforce,GX 5200. I've stated the new power supply's capacity,
Aside from the fact that the machine - as was in the beginning - was not powering up properly, I guess I figured a new power supply might help.
Anything else (that isn't already in my initial description)?

It would help to know the motherboard model number or the system model if it's something like a Dell or HP.

The power supply was a good guess but it could also be the motherboard or even both the power supply and motheboard.

I know it's been awhile since it was running but do you or your son remember any details about what may have happened when it quit working?

When you start it up do you get any beeps? Did the new video card replace an older card or were you previously using an on-board video connection? You might want to go back to whatever video connection you had before.

The cd drives should open if they are properly powered even if the motherboard isn't booting.

Motherbd is nice and clean but the only tags I see are "Sempron" and "Elite Group". The machine was made by Northrup. (Yes, I did contact them - no help excepting to say I should make sure the power supply rail is 12v. They didn't know the video card was a card and not attached to the mbd.) Little by little I'm remembering what occurred - the monitor screen picture went awry and then blanked out. I figured at the time, it was the video card and decided to upgrade it. It didn't solve the problem so then I got a new power supply. Again nothing. No turn on at all and I figured I had goofed and didn't connect the thing correctly, i.e., to the power switch. Well, the part about the switch not working was correct. However, it wasn't until now that I finally investigated by taking off the computer front. And sure enough, the power switch was not working through the button on the outside. I used the switch alone and that's now how all the bells and whistles work but not the monitor and cd devices.
No beeps. And, yes, I agree the cd drives should open but they don't.
When plugged in - even if not hooked up to the computer - monitor goes green a few seconds and then yellow. Same thing if cabled to the computer.
I have used another working monitor. Same thing - zilch. Only thing I haven't done is use another video card cable hookup. I have umpteen hundreds of cables but not this one. A friend gave me a couple of used cables.. I'll see if one of them is the correct pin configuration or if I have an adapter some place around here. Also I'll go through each connection one by one (again) to make certain everything's seated.

Elite group probably refers to ECS motherboards. There should be a model number on the printed circuit board itself, not on any of the attached hardware.

The only name I see on the board is Sempron. But that doesn't mean there is nothing more. While looking for something on the printed thing, I stumbled across the 4-pin female connector. I had looked and looked for that thing - never could find anything vaguely resembling it.
I'm going to re-install the video card that has a fan on it. I'll see if the fan works, then it's getting power. I would presume so anyway.
Not tonight though.

Sempron is the type of AMD CPU that you evidently have. If you are reading that then there may not be a heat sink/fan attached to the top of the CPU. Without that heat sink/fan the computer will not run.

The 4 pin female connector is from the power supply? If so, there are usually more connectors than are needed for most installations.

See the links below to help identify what you are seeing.

I don't have a schematic for this computer but that would sure speed up the where and what of this board. I do have a fan (and a blue light) atop the CPU - it spins and lights up. Nevertheless, I was wondering about the CPU. I had to replace one in another computer. The Sempron label is on the mbd along side it. Yes, that's right it is an AMD.
The pics and all the extra defining material are great. I recognize the cables I have with the power supply, e.g., the 20+4 layout, the 4-pin peripheral connectors and of course, now, the 4 pin one. I'm not sure about the SATA cable - doesn't look like anything I have. But maybe...
Anyway, I won't be doing much with this computer until the weekend. I also found a lot of info re the video cd. Mine is a three section setup and snaps into place with the monitor hooking directly on to it. I have one that has a fan on it - I'll install that to see if it spins with power to it.
Thanks much for the reference info. Helps a lot. And I'm very appreciative of all your help.
