testing to see if bios loads...

[badperson]

Hi,
in my new build,

I have the chips on the mobo, heatsinks on, mobo in case, psu hooked up to mobo, case wires hooked to mobo

I do NOT have a HD or graphics card hooked up yet.
When I turn the switch on the back of the PSU, I get a green LED light on the mobo,
when I hit the power switch on the case, nothing happens; the case fans and heatsinks don't start spinning.

I figure I'll add a hard drive and graphics card, boot up with a montior plugged in and take it from there, but what should be happening at this point?
thanks!!

Try this:

This will tell you if the motherboard is bad or if it is just grounding out to the case.

You mentioned in another thread that you had trouble with the power supply connectors, what way did you end up connecting it?

HI,


I did end up connecting that power supply, I have another one I'll use for testing if I'm still having problems...I'll go through the steps in the post above..., although creating the short circuit seems kind of tricky, but it did make sense.

thanks for the help

Hi,

back in another post, I described three power connectors that were supposed to go to my mobo; a 24 pin (got it), and 8 pin(got that too) and a 4 pin. I have 6 pin cables, a 4 pin jack on the mobo; i plugged in the 6 pin jack.

then, when I got everything connected, I tried to power up, nothing. I removed the 6-pin cable from the 4 pin jack, and the machine powered up!

But...the fans have this kind of pulsing rhythm, and the bios led flashes "FF". For the first 30 seconds or so I get this beeping noise...am i doing something wrong?

going to power up with a monitor attached...right now I'm just on the floor.
thanks,

You have RAM in the motherboard right?

[badperson]

not sure....
I have 4 sticks of 1gb ram. I thought they were in properly.

there are 16 ram slots, with two areas holding 8 sticks each.
I have all four of my sticks in 1 area. Should they be split up? I thought the manual said it would detect them anywhere.

I'll remove all but one stick and see what that does.

Also, I booted up with a monitor attached, didn't see any output at all. I attached the monitor to the matching input from the mobo itself, not the graphics card,which has a different type connector.

Is that wrong?

Yes just use one stick of RAM in the primary bank and use the on-board video. Let's get you back to being able to power up. The motherboard book should have a list of what the errors mean (FF and beep code) that you are getting.

HI,

how do I know which is the primary bank?

Also, does the pulsating rhythm of the fans indicate I'm not getting enough power?

There should be a RAM slot labeled bank 0 and that is the primary slot. You might need to look in the motherboard booklet. It's hard to say about the pulsating fans...are they speeding up and slowing down? Could be fluctuating voltage but it's hard to say for sure without checking the pins with a voltmeter. What type of motherboard and power supply do you have?

[badperson]

I put the ram in what I believe are the right spots;
slots 6 and 7 in each bank, which appears to be the minimum amount of ram you can have for two cpu's.

Again, I booted up, but got no output on the monitor.
I'm using a belkin switch that has two computers on it, so I may try plugging directly into the monitor to rule out a problem there, but I can't see why it would be an issue.

Also, those pulsing fans are weird...I've gotta believe it's a power supply issue.

When I hit the power switch, the led display also flashes at the same rhythm as the cpu fans.

It's a 750w psu, so I would think that would be enough, but you never know, this is a big extended ATX mobo with two 4 core chips, so maybe it isn't.

Ah sorry, I just noticed the link to your build specs. I am out of suggestions, hopefully someone else will chime in. I would definitely take the switch out of the loop to rule it out.

thanks,

this is from the online manual for my motherboard:

2.10 - Installing the Power Supply There are three power connectors on your Thunder n3600M S2932-E. The Thunder n3600M S2932-E requires that you have an EPS12V power supply that has a 24-pin, an 8-pin and a 4-pin power connectors. NOTE: Please be aware that ATX 2.x, ATX12V and ATXGES power supplies may not be compatible with the board and can damage the motherboard and/or CPU(s).

I have the 24 and 8, but not the third 4-pin.
I've been looking on newegg for a compliant psu, but can't find one...
anyone have an idea?
