So my PC components arrived today so i could buld it. The specs/components are:

NZXT Hush Case
Arctic power 600watts PSU
2 x 1GB OCZ DDR2 6400 RAM
Asus PK5C Mobo
Samsung Spinpoint 500GB HDD
ATI Sapphire X1950 Pro
Intel E8400 2 x 3.0Ghz CPU

So it's all put together (as dictated by the manual) and whe I plug it in the Mobo LED lights up green. But, when I press the power button everything turns on for about half a second then turns off again (the case fans and CPU fan spin).
I've reset the Mobo using the CPU jumping... but im at a loss of what to do...

Any suggestions?

hmm i came across this problem before with a PC, i switched out the power supply with one i definately knew was working and it worked, so that may be worth trying.

The power supply is fine. The lights turn on and the fan spins so all is good. You might not have the connections made right. Check the wires that go from the power button to the mobo.
Make sure those are all on the right pins.
#5
Make sure you put the motherboard power connectors in the right way. Same thing happened to me, and that was the problem. One way goes in much easier than the other, that should tell you. Hope that helps.

I h ave checked all the connections for the power supply to the mobo, and they're all fine. All plugged in the right way...
I just swapped out the CPU and put the P4 from my current machine in there and the same thing is happening, it's deffinatly something to do with the motherboard.

Did you install a OS? I am pretty sure the HDD is unformatted if you bought it all in parts. Maybe you should start the CPU with your OS disk that you bought right?

Have you tried all the mobo connections? it could be something else not functioning and causing it to not power-on properly.

^ Yeah it used the 4 pin and the 20 + 4 Pin plugs and they're all plugged in at the moment.
I've tried all the components plugged in and not plugged in and the same thing is happening every time.

Get a screwdriver and ground yourself of any static electricity. Find the area where the power pins are located (the pins that connect to your power button), and touch two pins at the same time (ONLY TWO) with your screwdriver until you find the ones that power up the computer. Hold them there, and see if your computer runs fine that way. That's so you can isolate your power-on pins.

Did you say you tried it with the old CPU? Couldn't quite get the jist of what you said before.

What i would do, is try using an old hard drive, thats already formatted to an OS. See if that works.
#12
^ Yes. I used the Pentium 4 from my old (but still current) computer in the CPU slot in the place of the E8400 i have for the new one.

I dont have the right cablage to do that.

Can you not use the cables from the new HD and just use an old on instead? If you know that works, you can hook up the new one to your old PC and format it on there.
#14
I would still try swapping the power supply.

Just installing an OS isn't going to stop it powering itself off.

No the HD isn't the problem its just not booting. Not even got to the HD reading part yet.
I dont have another PSU.
I can't install the OS, the system wont even get up to the BIOS.

No My dell doesn't support SATA HDs it uses some wierd one... it's not IDE either.

Scroll up on this page, do what the guy who suggesting testing the power with screwdrivers did. I read it and it sounds like a good place to start.

Since we know its not the Power supply, the hard drive or the mobo, it would be a good place to start on everything else.

Nice specs on the PC btw. Is it going to be running Vista for gaming?
#19
Id double check all wiring, also do the pin test to test out the PSU. Its the same test for bleeding a watercooled system.

Take out the Graphics card if its in, you can always install this later.

Failing that, kick the **** out of it.

I'm not sure exactly what im being told to do about the Pin test. And It's not the processor either.

No im running XP I can't be bothered with Vista till they sort the compatability out.

Ask on a pc forum, thats youre best bet.

It wont be the processor FFS

You have P-mail.
#22
What I mean is, do you mean the power cables coming from the PSU or the pins on the motherboard itself?

Do you know where the pins that you connect the power button to are located? If you know the area, get a screwdriver and ground yourself from any static electricity. Touch and hold the screwdriver tip to two adjacent pins (any two, but make sure its ONLY two), and your system should power up when you touch the right ones. Take the screwdriver away, and the computer should still be running. Let it run for a few seconds to make sure there are no problems. If all is good, touch the pins again to power down the computer, and connect those pins via the power button connector.

There is a guide online for it, I'll try to find it.

EDIT: The pins on your motherboard.

Ah i see, yeah i know where they are. I'll go and try it now.

EDIT: Tried it, same thing happened. Power on for .5s then straight off again.

Then there's probably something wrong with the mobo. Try reordering that, and if that's not the case, reorder the PSU.

I hate when computer maintenance is a pain in the ass.
