Motherboard problem?

Hello.

I've just built my first computer. I can't figure out this particular problem.

Everything is connected to where they are supposed to be. When I turn on the PC, all the fans and LED lights turn on but none of the peripherals do. At first I thought this could possibly be a PSU problem so I disconnected the IDE cables and just had power going to the CD-ROM/Hard drive and they come on and work. I've gone through all the plugs to ensure I don't have any and so I thought it could be the IDE cable so I tested them by only connecting the HDD and it didn't turn on or spin. I did the same thing to the CD-ROM and that didn't work either (I used both master/slave connectors for testing.) I then switched the IDE cables with ones I know work and get the same results.
I do have the CPU fan and 1 case fan powered via the motherboard and they are working. Could the motherboard be fine but the memory or CPU be bad?

Here are the mobo specs:

Supported CPU: Socket 478 Intel Pentium 4 Processors(HT)
Chipset: HT1683(NB) + HT1563(SB)
FSB: 800/533/400MHz
RAM: 2x DIMM support DDR400/333/266 Max 2GB
IDE: 2x UltraDMA 133 up to 4 Devices
Slots: 1x AGP 8X, 4x PCI, 1x CNR
Ports: 2xPS2,1xCOM,1xLPT,1xLAN,6xUSB2.0(Rear 4),Audio Ports
Onboard Audio: CMI9738 4-channel AC97 Audio
Onboard LAN: Realtek 8201BL 10/100Mbps
Form Factor: ATX

OO. I just realized something by posting those specs. I am re-using a HD from an older computer and CD-ROM. Will they not work if they are not UltraDMA or will this not have any affect?

Oh, the other specs:

256MB DDR PC3200
2.4GHz Celeron D 256k Cache 533 FSB
400W PSU

Hi,

With all the drives disconnected does the computer show a post screen and can you enter bios?

If so then the mobo, cpu and ram are most likely good if not I would suspect a bad mobo or bad video card.

Try the other video card if no go then

Remove the mobo from the case and place on a piece of cardboard
Install only cpu with hsf, 1 stick ram in the correct dimm,video card,psu,case speaker and case switch, mouse,keyboard, monitor
Make sure the 4 pin 12v connector from the psu to the mobo is connected along with the 20 pin
Clear the cmos
Verify all jumpers are set correct especially the clear cmos jumper
Verify the cpu fan is connected to the correct header on the mobo
power on and post back your results.

Sorry it has been a while since I've been here. Busy with school + 50 hr work weeks (I'm a receiver for Krogers Food Dist. Warehouse) + family.

Before posting here, I e-mailed the support staff from the mfg. It turns out that when I read the description of the motherboard, it said that it supported Pentium 4 and Celeron processors. So I bought a Celeron D processor to go in this. BUT it turns out that it supports only Pentium 4 Northwood /Williamette (or similar - can't remember the name) and the just the plain jane processor Celeron.

So my advice for future prospective mobo buyers, if the description of the motherboard *isn't* specific to what you want, contact the mfg first BEFORE making the purchase.

Note: MFG = Manufacturer
