A couple of questions first!
Is the switch on the power supply turned on?
Did you have to change the clear cmos jumper on the motherboard?

More questions later!

On the back of the powersupply (not all units) have a switch on the back. Is it turned on?

If pushed to O - Off
If pushed to | - On

Other things that may help other people here to help give troubleshooting advise:

What systemboard, and CPU are you using?
What powersupply are you installing?
Is your AC outlet 115V(US) or 220V(EU)?

Heh, there might be other questions to be asked.

I suppose you have the 20 pin snapped on securely.

Do you have the 4 pin square/power connected, near the CPU socket?

If all power connections are on properly..

The worst thing that could happen, is that you've been shipped a bad PSU. It has happened to me. I put a system together, hit the power switch and... rechecked all connections and... heh nada.

Took the system back, gave me another PSU, fired up.

ok, ive checked the comp agian.
i did infact (giggle) have the 20 pin unplugged, but it still didnt work.
so, furiously i nuged and wiggled the power cord and turned the power supply back on. my eyes poped out, the mobo's power LED went on. woo hoo!~ my first comp worked :D

THANKS!!!

but unfortunatly, i have one more question...
i plugged in an old pci video card, and i cant see anything on the screen. am i suppose to have the AGP card, or it doesnt matter?

thanks!!

i added 2 different video cards and they both still doesnt work.
ive added one from my old PC (AGP) and ive added one from my Mac (AGP). the video card that i was using on my first installation was a PCI.

is there a PCI/AGP power plug or something on the MOBO?

thanks,

d.suzuki.

Ummm... be sure not to stick a AGP card that is 3.3v to that interface. If you do, you will fry it, since it's a 1.5v AGP interface.

Though, it shouldn't fit if it was. What is the video card that you are intending to use?

I guess the other question is.. when it was powered on, with the 1st card you had in it... was it beeping?

And if it was beeping, how many times did it beep, in the interval.

Example: 8 beeps..

beep, beep, beep, beep, beep, beep, beep, beep, pause...


Edit: Doh.. don't tell me that board doesn't have an intergrated speaker.. :roll:

Do you have the PC speaker hooked up? Does the case/tower provide one?

Also Asus does have a voice to tell problems in place of the PC speaker. So you need reg speakers hooked up to the onboard sound card jack.

to get this going you should take a moment and list everything you have installed in the computer.

If you intend to use a pci video card it should work but I think you will need to set it correctly in the BIOS.

I would try with the AGP card you have first to check that it's booting and what not.

Also list your memory and what other cards you have installed, processor the whole bit.

Do you need to plug your video card directly to your PSU? On the back of it there should be a power plug.

Couple things to keep in mind as your swapping parts around -- whenever you add or remove something from your PC (or other peoples) make sure the power cord between the power supply and the wall is UNplugged.

Errr.. if you unplug the PC from the outlet, you basically have no ground anymore.

That is one of the purposes for the off/on swich on the back of the PSU.

At least, that is what I thought.

so long as you mantain contact with the computer (elecrostatic wrist band or hand or arm touching the case) you'll be fine. by doing that your electically neutral to the computer and there can be no static discharges regardless if the machine is plugged in or not. so i always unplug the computer i'm working on and would suggest you do the same. i'm not will to trust $1000+ dollars to 0.25 cent switch :)

Ok, when you plugged in the 20 pin cable from the power supply you got some lights and activity, but No post. I saw where one person asked if you had the square 4 pin from the power supply plugged into the mother board, I never saw any responce from you!
Is it plugged in also?

no, the case didnt come with any speakers so, i didnt have any speakers plugged in. I guess thats the reason why i didnt get any beeps.


::Also Asus does have a voice to tell problems in place of the PC speaker. So you need reg speakers hooked up to the onboard sound card jack.
as in theres an automated voice that comes on and tells you what the problems are? thats fuckin hot! :D

Is your CPU fan connected to the CPU fan connector? Is it properly installed? Did it have thermal compound on it?

Did you plug in your monitor before turning on the PC?
Is at least a keyboard hooked up? Triple check connection even I make simple mistakes :p

The 4 pin square plug has yellow and black wires. 12V to power the CPU, if I remember correctly.

If you could get/find some speakers to hook up to the soundcard, you might be able to figure out other problems going on.

Might want to reseat the RAM dimms. Be sure they are seated properly.

I hope you seated the CPU/HSF correctly with thermal grease/compound.

Actually, did a company put those parts on for you, or did you put them on yourself?

Some more about the power supply;

Does your power supply have a voltage switch, you know, 220 or 115 volts?

And check your manual for the Clear CMOS pins please, to be sure they are jumped correctly.

Have you plugged in the Power-Switch to the right pins on the motherboard?
