	Building a box... won't boot... help :D Support Apolyton, buy Alpha Centauri

(mods: if you have to kill a thread plz kill the "mobo time" thread)

ok, i bought some parts and i threw them together, pushed the power button, and nothing.

it's like i didnt hit the button.

i believe all the jumpers / power connectores are set in the mobo, what else could be causing this?

Do the fans turn on?

In any case I'm sure you also hooked up all the power supply stuff inside too.

Including hooking up the on/off switch to the mobo.

Frogger: no, nothing turns on at all.

Diss: i believe i hooked up the switch to the mobo correctly.

Well then trace the power supply to the fans. They're a lot less complicated than the motherboard is. There should be a hard power switch somewhere along the line. If you have a multimeter start checking connections.

no multimeter, sadly.

i'll start looking it over, though.

any other ideas?

did you get a new power supply?

I heard somewhere that new powerful motherboards and cases (I have seen some cases with 4 fans) require better power supplies.

But yes trace the power supply to the fans and motherboard. And if the on off switch is correctly plugged in, I'm not sure what the problem can be.

here's another commonly overlooked thing. if you buy a case that doesn't have mobo raisers built in or attachable that separates your mobo from the metal mobo holder, get raisers.

if there's any contact between the mobo and the metal plate, it won't boot.

Yes, do check this out.

This was the problem I had when building my last machine... luckily I didn't fry the mobo...

what i honestly don't understand is why case manufacturers don't always provide the raisers.

If that doesn't help, get the system down to its simplest configuration as possible - ie mobo, memory and graphics card only. That way there are less things that could cause the comp not to boot.

Of course, this is a last-ditch takes-lots-of-effort thing.

i re-connected just the power supply and the power button the the old motherboard, and it turned the box on.

i took the ram out of the old mobo, still powered on.

i took the CPU out of it, still powered it up.

i'm now removing everything systematically until it works. tomorrow i may have to go to compusa and throw this back in their face.

Even though your power supply is rated by the manufactor at 300W, in fact it might not be the case.

Just take it out and plug it in. If it turns on, e.g. the fan starts turning, most likely you don't have a big enough power supply.

Unplug everything from the power supply. Plug it into a wall outlet. Switch the computer on. Does the fan on the power supply turn on?

by powersupply, i mean the ahrdware that allows me to plug into a wall.



how can i plug the mobo in to the wall w/o it?

	Suffering from ads?

Sorry.

What I meant is leave the power supply inside the computer, but unplug it from the mobo and any other devices you have connected to it.

When you switch the power on, does the power supply fan comes on?

the power supply i have does not have an on/off switch on it itself, so i cant test it that way.

thanks anyway though. i'm probably going to go to compusa tomorrow and tear some guys face off.

That's why I said "leave the power supply in the case," so you can use that on/off switch.

I think it's too late at night for you.

i have been up for 83 hours, but thats not the point.

i already tried ooking the bare mobo to the powersupply, and it didn't work.

Did the fan on the power supply come on? Did the LED on the mobo light up?
