Will not post, PC will not boot

I have a socket 478 custom built pc, within in the past two weeks my pc not longer will boot. It has power, I get no posting beeps or video when I turn it on. I tried a new video card, it did not help. Next I replaced the mother board with this PC Chips M981G. After hooking up all cables and double checking all set up. I powered on the pc with the new motherboard. Same results, no posting beeps, no video. I am running out of ideas. Could it be a DOA board? Could it be the CPU? If it was the cpu I figured I would atleast see an error when the pc tried to boot on the screen. Do you have any ideas on what else I can do to narrow down this problem. I plan on sending the new mb back in for a replacement, but, I'm not confident this will help. Thanks for your help.

Try re-seating the memory modules. Also, go to barebones config (no hard drive, floppy....nothing but mobo, cpu, memory, video, kb)

Presario S6000CL

Processor isn't turning on.
Since this is an old motherboard, (2003), that has a Socket A, (Also known as Socket 462), processor socket, I would like you to look at the motherboard, for these possibly bad components,

(Computer on a table, unplugged from power, computer case open, Anti-Static Precautions followed),

http://www.capacitorlab.com/visible-failures/index.htm

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00063254&lc=en&cc=us&dlc=en&product=386640#c00063254_doc

Electrolytic Capacitors;
Some are used in the Motherboard Voltage Regulator Circuit.
Part of what the MVRC does is to regulate voltage for the Processor.
The Processor MUST have a steady, clean supply of voltage, and it MUST be within a very Tight tolerance range.

The Electrolytic Capacitors used in the MVRC for the Processor, are in a Series circuit. (Most strings of Christmas tree lights are in a Series circuit)
IF, just one goes bad, the circuit will not operate.

http://www.hardwaresecrets.com/article/616

Also check the Thermal Paste. See if it has dried up. (Due to the LOW cost, and insurance of having good thermal paste, it is best to just replace it)

Right i need the size or model for the cooling fan that all intelboard mode E210882

The Heatsink/Fan combo is based on the processor socket used.

After a few search hits, I have seen E210882 on Intel based motherboards, that use two different processor sockets.
The Socket 478, and the LGA 775 processor socket.

The socket for the Socket 478 has the pin holes. The Processor has the pins. (478 of them)

http://en.wikipedia.org/wiki/Socket_478

The socket for the LGA 775 processor socket has the pins. The Processor has the pin holes. (775 of them)

http://en.wikipedia.org/wiki/LGA_775

Identify which processor socket you have, buy accordingly as to the Heatsink/Fan combo.

One example of a Heatsink/Fan combo for an Socket 478 processor socket,
(Only Intel uses the Socket 478 for their Processors),

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=578161&CatId=795

One example of a Heatsink/Fan combo for an LGA 775 processor socket,
(Only Intel uses the LGA 775 socket for their Processors),

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3302824&CatId=1588

Remember to observe Anti-Static Precautions, Thoroughly clean the top of the Processor's case, and aplly fresh new thermal paste.
(A Processor is the most susceptible hardware component to Static shock)

[ Example of thermal paste,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3071621&CatId=503 ]

If you would like advice on how to properly clean the processor's case, properly apply thermal paste, and/or what Anti-Static Precautions are, post in a Comment.

CPu fan turns for 1 second and then stops.

If all was working fine before, then, you have either not connected the cpu power cable, as is sometimes required other than being powered by the processor socket, or your power supply unit is not pentium 4 compatable and is unable to power the processor.

I have a Boot Problem with my INTEL P4 3.0Ghz. 800Mhz FSB,1M L2 Cache, Socket 478 CPU

I have experienced something similar with my new Core2Duo processor and a fairly new Socket 775 processor. Troubleshooting it led me to believe the CPU simply wasn't compatible with the motherboard. Although it's a shot in the dark, I suggest that you try out some of the following: - Did you try pulling out the graphics card to see if you got it to POST then? The graphics card or the monitor may need replacing. - Did you remove the RAM? - Are you sure all cables are attached properly? - Try to take out the CPU, talk to a friend with a socket 478 motherboard and replace his CPU with your CPU. Does it work now? If yes, motherboard needs to be replaced.
