Hey everyone, I just bought a new computer, well all the parts for one, and I was sitting here for like 5 hours putting it all together with a friend. We went to turn it on and it turned on for like a split second, fans, LED lights, everything, then it all shut off... I don't know what is causing this. I have a AMD 64 3800+ processor, one of those new really good ones, lol. Anyways, my friend an I think its the processor. Or like 5% the motherboard... Maybe you all know why? Thanks... Ill be watching this post, so ill respond when you type something if you know/have any ideas.

Hi,

Try the following
1 clear the cmos
2 check the cpu fan is connected to the correct header on the mobo
3 check the 20 pin connecter from the psu to the mobo is secure and also 4 pin
4 verify all jumpers are set correctly

Check for these and post back if no go

IM reading on how to clear the CMOS, but what does it mean to "short: CLear Cmos"? Theres a picture here of where it is, and i guess "Open: Normal" is when nothing is plugged in. The "short: clear CMOS" is filled in with some gray shadeing... I guess i take something and plug it in there? What do i use to short it?

Cmos is a chip on the mobo that stores your bios info, bios is needed to start your computer, by clearing it you are setting it to factory defaults this is sometimes needed with a new board.

You clear cmos by moving a jumper on the board from pins 1&2 to pins 2&3 waiting 5 minutes and then moving back to pins 1&2. Do this with the machine off and unpluged.

The jumper is usually located near the battery and is labled cmos but very small.

Make sure this jumper is on pins 1&2 when you power on or that could cause what you have described.

What they mean by "short" is to move the jumper to the other pins just do as I described

It could it has the same effect as using the jumper

But if the cmos jumper is not on pins 1&2 the computer will not boot.

What mobo do you have I will download a manual so I can tell you more
