New Build Problems please HELP!
I have recently purchased all my parts for my computer. I received it a few days ago. I put everything together. So i press the power button, I was suprise to find that it start it up (nothing was diaplayedon monitor) for a few seconds and just shutdown. All fans and light where on. So i decided to trouble shoot and take one peace out at the time to see what would happen. I took everything out and it still turn off. So i took out the CPU and that was the only time that it stayed on. The CPU was a little warm but even still i have a heat sink so i dont think it is that my CPU is over heating. I dont know what it could be, any ideas?
Motherboard:Asus P5ND2-SLI Socket 775 Motherboard
CPU:Intel P4 651 3.4Ghz HT 2M 800FSB Socket 775
Video Card:eVGA GeForce 7800 GT CO
Ram:Buffalo Select 1024MB PC4200 DDR2 533MHz
Power Supply:450w

Are you using thermal paste in between the heatsink and the CPU? If the answer is no, do NOT start up the computer again until you have applied a thin coat of thermal paste.
Have you reset the BIOS?
It varies if i leave it alone for a lil while itll last 10-20sec on. If i keep pressing the power button it will get to the point that it will just shutoff once u press it.
The heat sink was installed with Thermal Compound and it still does the samething.
Yes i took out the battery and the pin.

I'm a little confused when you say "pushed the button," as that seems to indicate you are using the power on/off button usually located on the front panel of most boxes. This switch is under the BIOS control of the Power Management Function (correct me those of higher knowledge if I'm wrong), and can be set to varying seconds of response. I'd be more interested if you had the same problem using the rocker switch (provided on most "good+" PS's; it is usually located near the female power plug, in the rear of the machine (where the PS fan vent is usually located). If you have the same problem there then I would say you need to replace your PS. As PS's are non-FRU (non-field replaceable units), because they can build up very high, even leathal, voltages in their capacitance function of converting AC to DC).
As to your question of how much/large a PS do you need the following web page may be of assistance in assisting you here: http://www.jscustompcs.com/power_supply/;
it has a neat inventory from CPU to adapter cards of what is in your case and will recommend a minimum PS requirement. However, remember always install a larger PS than the minimum requirements (by at least 50%, as you have to consider future system upgrades and add-ons).
I'd be interested in your findings, so keep posting. Don't forget to read about Folding@home and join Team 93.

Second Are the other 2 power plugs plugged into the mobo?(there is a square one with 4 pins and one that looks like a cd power connector)
Third do you have 1 video card? Is the mobo set to SLI?
Have you tried moving the memory to different slots?
Im pretty sure the PS that came with the case is "NOT" made for SLI or even a 7800. Usually they say 450 Watts but really are much less.
What will happen if i change that?
If you mean the little swith where u change the amount of voltage from the 110v to 120v or what ever. i tried changing that and it mess up my power supply so i got it replaced.
Yes it does have a 24 pin I have conected them in the right place and everything.
Yes they are. There put in the correct place and everything.
I have 1 video card the 7800 and its set to single SLI.
I tryied putting them in a different slot, all 4 different slots and still nothing.
so i recently connected the motherboards speaker and all i get is one long beep. the thing that doesnt make sense is that if it is the power supply why does it keep turning off and if i leave it alone for a little while it last longer on, but if i keep pressing the power button it turns off even faster.
do you have other memory or another computer to test your memory on?

and later on are u going to use SLI?
As for the BIOS flash, that's a good idea, but don't risk it until the rest of the system is relatively stable. If it cuts out on you in the middle of a flash you're going to end up either paying someone else to reflash it for you, or buying a whole new chip altogether.
yea it cost me like $30 to get a new bios chip pre-flashed from asus when I got my system. It wouldnt boot so a friend told me i should try it, and it worked.
(Look on the intitial screen when you first turn the computer on. There should be a version number and a release date listed.)
The thing is that i dont get to the boot screen. I dont get any picture on the screen. Everything begings to power on and then it just shuts off after 20 sec. nothing is displayed just one long beep. I called it in yesterday and they where no help so i decided to get it replaced. To see if that is the case i should be receiving it today. Im hoping that it was the mobo. And what do you think about what i said before about the PSU?
I turned off my comp and removed my memory, than I restarted it and there was a long beep, and black screen. Same like you said. So check the memory in another comp or try other memory in yours.
As to the PS i checked your PS and it MIGHT work a little. It should start at least. Do you have a cheaper Video card to try (the 7800 needs lots of power)
If you are gonna go SLI than get a good PS (600watts min) now so you dont have to get another later.
If you are not sure and 1 videocard if fine for a while than a good 450Watt is fine.
The PS that comes with your comp IS NOT GOOD. It is barely good enough for onboard graphics.
To find a good PS look for the reviews. Some good ones are Silverstone, Antec, Seasonic, Enermax and some people like OCZ. For a good 450 or 520watt you will probably pay about $60-80. For a 600and up PS Figure $100 and up. Dont be cheap with the PS as it is the backbone of your computer.
I am about to take everthing out of the case, before i rma the mobo.There seems to be no connection btw my graphic card and screen.
I have a total blank screen everything powers on fine, but no blue screen.
Let's know how you get on.
Your heatsink is probably not flat on the cpu. Or you are the unluckiest person on earth.
I have built over 400 computers and have not had this many problems on ALL of them together.
Since you are using a Intel (they run hot)mabye the heatsink is not good enough
Or your CPU is burning up.
What kind of Heatsink and fan are you using? If its the stock one throw it away and get this,
