What kind the motherboard you have? is it supported jumperless or jumper configuration? Pins of Reset, HDD, Speaker, Power LED, etc...

1. Reseat the memory, power supply to MOBO connector and CPU.

2. Remove all the peripherals except for the memory, video card and CPU. Disconnect all the drive data cables and power cords.

3. Reboot the system. If the system comes up to a post and fails to detect the HDD's then power off and reinstall the HDD power cord and data cable. The computer at this point should be able to boot to windows.

4. At this point if it does boot, shut it down and start installing one piece of hardware after another. Reboot between each installation.

5. If it fails to boot with a particular PCI component then try a different slot. Some components and chipsets are sensitive if the device requires busmastering. If it doesn't work in any slot, it is the likely culprit.

I have had similar problems with various solutions. A bad power supply could be causing your problems - despite the fact that it "seems" to be supplying power correctly. If there are no POST beeps, the memory is probably ok, but you may try swapping it out. The last step would be to swap out the motherboard.

Did it ever work? or is this a new build?

Did you Disconnect everything except ram, cpu and video card as micwal said? (keep the internal speaker and power switch connected) it should boot.

If it doesn't boot the Ram, cpu, video card, motherboard or power supply are probably bad (get hold of test components to test the CPU, Ram, Video Card and power supply.)If there are no beep codes from internal speaker it is probably the CPU or Motherboard.

If it did boot then add components one at a time until it doesn't boot. The last component added is your problem.

This is old motherboard with socket 370. I have similar issue very long time ago. I suggest to re-check connection between video card and AGP slot. Also, re-check the configuration of wired jumpers at headers reset, hdd, power led. Let me know if those would help.

Did you use motherboard risers when you screwed in the motherboard?
