I just bought a new ECS p4 mainboard. I installed the new motherboard set all the the jumpers correctly and doubled checked them and installed a 1.6 gig p4 in there. I put the cmos jumper on clear and it did fine when I put it on normal i got nothing i thought it was the bios b/c ecs have a lot of updates for it but it won't boot up to allow me to update it so now im lost i have already ruled out the p4 chip by trying in another system can some one please help.

Good troubleshooting steps to do is to pull everything off of the motherboard except the power supply, CPU, video card and see if you get anything. If so start putting each peiece back one at a time trying it until you find the problem child. GoodLuck!

Let me know

Double check the jumper orientations.

I wonder if you have the jumpering confused.
Many manuals make it difficult to distinguish between the shorted and open posistion for the jumper.

Why, most motherboards do not boot with the CMOS jumper set to clear.
You usually get a blank screen, or a simple notification when you boot up with the jumper in the clear CMOS position.

If I am off base, please provide the details of what happens when you boot up with the jumper set to clear.

I have already check and double the jumper settings and it doesn't do anything when i put it on normal the pc won't turn on at all but when I put it on clear as u said and i get a blank screeen but the computer at least comes on

if its a new board you have a manual with all instruction how to set board-drivers. did you do this step ny step? if so, look for a graphic image of the board and explanations of the jumpers. check every jumper described.if this does not work, an expert(from here) must have all jumper-positions and the exact mainboard-model-type plus version(ver.xxx)-

Okay, try this.

Unplug the power cord from power supply, and remove the CMOS battery for about 30 - 60 minutes.

Don't ask me why, but I have had to do this with a few motherboards after clearing the BIOS settings.

No..no, don't mean to be rude to above poster... but clear your bios this way.

turn off your comp...and disconnect it from the power supply.

1.remove the battery

2.put on the clear bios jumper and leave it for 5 seconds...now set it back tonormal

3.put the battery back in and power up.

so what happens now?

YOU MIGHT WANT TO CHECK THE WRITE/PROTECT JUMPER/
SWITCH. IT SHOULD BE NEAR YOUR BIOS CHIP. OR TRY
RUNNING BIOS RECOVERY, MOST BIO'S HAVE THIS.
BLACK SCREEN DOES NOT SOUND GOOD. REFER TO SCOTT
MULLER'S UPGRADING AND REPAIRING PCS

I ASSUMING THAT YOU HAVE NOT TRIED TO FLASH THE BIOS, JUST CLEARING THE CMOS SHOULDN'T PRODUCE THE PROBLEMS YOU DESCRIBE. MOST BIO'S HAVE A DEFAULT SETUP.CHECK WITH THE BIOS VENDER, AND
MAIN BOARD MANUFACTURE, SOME CHIPS ARE WRITE- PROTECTED, AND ANY ATTEMPT TO FLASH THEM IS NOT A GOOD THING TO DO. ALSO HAVE THE BOARD CHECKED, IT COULD BE FAILED MAINBOARD MEMORY. HOPE YOU CAN FIX IT.
WHAT A BUMMER HUH!!

Have you checked your memory? The computer will not boot if your memory is not seated right in the slot or in some cases it has to be in the first slot on the board. Also check to make sure that the memory is compatible with the motherboard.

and yet my computer still won't turn on for as long as im in normal bios seting but when i set it to clear cmos it does fine

ANSWER #7 WAS MY NEXT THOUGHT, IF THAT DOESN'T WORK YOU MIGHT CONSIDER BUYING A POST CARD. IF YOUR POWER SUPPLY IS OK YOU CAN USE A DIAGNOSTIC CARD SUCH AS POST-PROBE FROM MICRO 2000 (818) 547- 0125, R.A.C.E.R. 2 FROM ULTRA-X (800) 722-3789,
RACER 2 FROM MICRODATA (800) 539-0123
THESE ARE SUPPOSED TO BE THE BETTER ONES ON THE MARKET.
IF YOU DON'T KNOW THSES BABYS RUN TESTS AND REPORT RESULTS THRU LED CODES.
ALSO CHECK THAT THE BOARD ISN'T SHORTED OUT ON THE BACK SIDE FROM MOUNTING IN THE CASE.

by maggot

I KNOW THIS MIGHT SOUND SILLY, BUT IS YOUR MONITOR
WORKING? DON'T KNOW HOW MUCH THOSE POST-CARDS
COST, BUT IT MIGHT BE WORTH CHECKING INTO.
GOOD LUCK!!

I SEE YOU HAVEN'T GOT TO #8 YET, WELL ONE MORE
THING TO CHECK POWER SUPPLY, TURN ON COMPUTER
IF YOU CAN HEAR THE HARD DRIVE SPIN-UP THATS A GOOD SIGN IT'S WORKING, FANS ALONE DON'T MEAN BOARD
IS GETTING POWER, ALSO DOUBLE CHECK PLUG ORENTATION, POWER TO BOARD FOR CORRECT CONNECTION,
THOUGH MOST PLUGS ARE KEYED YOU NEVER KNOW.

If the m/c work fine in the clear cmos position and does not boot up in normal position do you think the wiring or the stamps are in the wrong position? is the board faulty as normally in the clear cmos position the board will not boot up.
