I have an Intel Pentium D 805 processor and a ECS P4M800PRO-M motherboard and when i hook it up nothing happens. I sent the motherboard back to the company and they replaced it, but that still didnt work so i sent the processor back and got another one and it still wont boot up. I have tried 3 different power supplies, about 4 sticks of ram, 2 or 3 different monitors and it still wont boot up, i dont know what to do...What should i do know?
 
That is a P4/Celeron Socket 775 model board that will run both DDR400 and DDR2533 memory and requires a 24pin connection from the power supply. Are you forgetting to plug in the four wire 12v connector that plugs in near the cpu socket along with using a 24 or 20+4 type connection?
 
No the motherboard isnt making any beep sounds when i turn on the pc, and yes every component is compatable with the motherboard. I plugged in the 4 wire 12v connector also...any more ideas?
 
You could have received a second defect board. Don't be too surprised at hearing that one. When asked to look over a new build last spring nothing would work in getting the first board to run. Everything else was spotless. Upon receiving the second defective replacement board the advice was then to choose either another model or a different make and model. Even the vendor admitted to probably having receive a bad batch of boards.
 
Could you clarify your situation a little. Are the fans, etc... spinning up?

If not, make sure that you've connected the power switch into the correct pins on the header. You may also want to try starting it by using a screwdriver to connect the two pins (this will ensure that you don't have a faulty power switch, which is unlikely, but you seemed to have checked most of the other components).

They said they tested the board before they sent it out.

Yes the cpu fan spins. The power switch works because i'm using it right now on my computer. I dont know what else to do.
 
When plugging in the wires for power and led lights on the front you could have simply jumped a pin or two with one power going to the HDled or Pled. Recheck those wires and all connections before spending in case it's only a simple mixup there.

I checked and all of them are correct.
 
Have you tried jumping the pins for the power switch directly to see if anything was seen then? That will indicate if the board is any good since you seem to have enough power. You start to wonder how well they tested the board when you brought it in.

How do you exactly do that?
 
First you would have to review the manual that comes along with the mother board in order to go over the wiring digram for the front panel harness. You trace the wires from the power switch to the pair of pins on the small block where the reset, power and hard drive leds are also plugged in. Once you have identified the two pins for the power you simply touch some small metal object like a paper clip, head of a small screw driver, or even a nail to make the quick momentary contact there in order to jump start the system.

The process only takes those few seconds to electronically switch the board on. If the power is sufficient you would see the system start up normally if there are no other problems then the switch itself. Remember that's working with live cirrent. You only want to jump those pins alone and not touch anything else where you send power directly into another component that runs on a different current or short directly to ground.
 
Well i'm sending the board back in for a new one again, and they said they would test the board with the same processor i have before they send it out to see if it works, so i'll go from there...thanks for your help so far.
 
I know it's miserable to have a system down. A friend last spring had me check out a new build to find two boards in a row were defective. Those were the exact same from the same vendor and I advised new model or new make and model. Another model was what it took there.
