Help guys. I am doing a new PC build and am at my wits end. About to toss this damn thing out. Ok this is what I have. .a P5N-E SLI board.. 8800 GT graphics.. Kingston DDR2 800 MHZ PC6400 Ram. 2 gigs (2X1) E6850 Processor and Heat Sink. 650 BFG power supply..
With the MB out and on a rubber mat. I hook up ONLY the basics. Graphics card, Ram. CPU and Heat Sink and turn the system on. Everything runs for about 2 seconds and then shuts down. I have checked to make sure the Heat Sink is firmly on the CPU.. CPU is firmly seated. It locks in. I have actually RMA’d the MB thinking there was an issue with that. But I got a replacement so that cant be the issue. What in the hell else can I look for. I mean I don’t have spares of everything to keep testing new stuff. What am I doing wrong here. Nothing else is hooked up and its not in the case yet. So what else is there for me to try?? Please help. As I am aggravated to no end. Thanks.
I have not gotten so far as post. Hell I cant get anything to run for more than a couple of seconds. So I cant tell anything else. I am just testing it out for the basics. I get no beeps . it just starts and then stops.
Do you have the 4-pin plug connected to the board? A PS/2 keyboard so that you can access the BIOS if it does bootup? Aux PCI-e plug connected to the 8800GT? Do you have another video card you can try? Even an old PCI card?
Explain how you mounted the CPU & HSF. Did you use paste or a thermal pad? If paste, did you apply it as shown here:

I don't particularly care for the PSU choice. +5V @ 54A? Totally unnecessary. 25A is plenty. That means the overall wattage rating is falsely inflated by approx 150W.

yes i have the 4 pin plug connected to the MB.. and the PCI-E power plug connected to the graphics card. i dont have a keyboard hooked up yet as i dont even get that far. as i said it doesnt even go through post. i gues i cna try a old PCI card. and see if that does anything. the CPU and heatsink. yes i am using Arctic silver 5 paste on the cpu/heatsink. and have done it according to instructions. from the website. since i had used the cpu on the previous MB. i used the cleaner 1 and 2 on them before i put new paste on it.

Remove the 8800GT, temporarily install a standard PCI video card, hookup a keyboard, then see if it'll fire up.

Can you try powering it up again right away, with the same result? Or do you have to wait a few minutes before it will even try. If you have to wait a while, that would indicate that too much current is being drawn and the power supply is shutting down for that reason.

In addition, if the suggestions above don't work, try removing one of the sticks of RAM and see what happens.

i will try to FIND a PCI card. it has been so long since i have used one. i only have older AGP cards. but PCI WOW.. i may have to buy one. have not used one of those in at least 8 years.. .. as for the power.. no i cna keep hitting the power button and it goes on for a second or 3 and then goes off again. .. and as for the ram. i guess i can try this but you are supposed to use two sticks at a time. whatever configuration they are in.

I don't think jam is suggesting you buy a PCI card. If you don't have one you can troubleshoot without it. One thing I didn't see mentioned was connecting the HS fan to the correct header, marked CPU. Your problem sounds like a PSU issue.
Remove any case to board wiring. That isn't necessary at this point. You can just use a screwdriver to momentarily short the two pins that are meant for the power button. You don't have any drives cables connected? You did try with a KBoard and monitor?
Try just ONE stick of RAM in the first slot. One other thing to try would be to clear the CMOS using the jumper on the MBoard. Power must be disconnected from the wall when clearing the CMOS.
You are connecting bothe the 20 and 4 wire power connectors to the MBoard?

"i guess i can try this but you are supposed to use two sticks at a time."
That's if you want dual channel to work. You can certainly troubleshoot using just one stick of RAM-try either slot, though some motherboards recommend using only one of the slots with one stick.

Ok hopefully someone is still reading this. This is what all I have done. I went out today and bought a new PCI video card as I had long since gotten rid of my other ones. I bought a new one.. and came home and tried it out. STILL the same result. Ok so that would mean it is not the video card. Then I tried taking out one stick of Ram. But it did the same thing and no beeps or anything it just shuts off after a couple of seconds. So I guess that brings it back down to either the processor. Or the MB again. I don’t have any other board to try this on. I dunno if I can take this processor to a PC shop and see if they will test it or not. Any other suggestions?? .. ok and all this time I DID have a Keyboard and monitor hooked up. Oh and to answer previous questions. No. I have no IDE or floppy cables or anything else connected to the MB.. the Heatsink Fan IS connected to the MB at the CPU Fan connector on the board.. not anything else. So the only thing connected to the MB from the PS is the power connector.. with the 20 and 4 wire connectors and that’s it. No case connections are on the board. I AM shorting the power switch on the MB with a screwdriver. So that eliminates the case. I also cleared CMOS taking the battery out and using the CLRTC and changed the jumper caps.. so that is done as well. Still no luck..

Do you have a different power supply to try? One other thing that I didn't see mentioned is this. If your MB doesn't support the processor or RAM you are trying to run. Are you sure all is well. The BIOS version could be old and not support the latest processor.
When you removed the HSink before, was the paste all squashed down to nothing? It is possible to install the HS backward.

Ok first of all yes this MB DOES support this processor. I am sure the bios may need an update for the 1333 FSB but it supports the processor. But if I cant get into the bios I cant do anything. Secondly. I went and put back in the original PSU which was a RaidMax 500W.. when I shorted the power with the screwdriver. This time the Heatsink fan ran for about 5-6 seconds but nothing else worked. I mean it didn’t go any further.. so .. does this mean the processor may be toast?? Could this be the whole issue?? .. and yes. when the HS was removed previously. the paste was mashed on both the processor and the HS

Try reseating the cpu. Then remove all memory to hear if you get any " none memory beeps" this would let you know at lest it processing.
