Title: Computer wont even start!
Post by: Kren on March 08, 2012, 08:29:03 am
Hi! I after spending all night installing a G1.Assassin I realized that the computer wont even start. All the case fans wont even spin, the dvd tray doesnt open, the liquid cooling system wont turn on either... and the only thing I notice when I hit the power button is that two of the eight phase leds turn on, one is orange and the other one is green. It is acting as if it wasnt receiving any power at all!

Do you have a case speaker connected?  If not, connect one and tell us what beeps you hear

Also, be sure you install the memory only in slots 2, 4, 6 physical from the CPU (labeled 1, 3, 5)

Thanks for the reply! Actually, the only external plug connected is the PSU's inlet and I have 4 ram memories installed in the 1st 2nd 4th and 6th slots. I already tried taking all those memories away and installing only one but it didnt work D:

I'm not sure what you mean about the PSU plug?  But you need to have a 24 pin cable connected from the PSU to the motherboard, and the 8 pin ATX EPS 12V cable as well (installs near the CPU)

Memory can only be used in the slots I mentioned if you are using three modules, or only in one of those same mentioned slots if using one module.   For now, just use three until you get going, as four modules is not ideal on X58 anyway.

Memory must be installed in 2, 4, 6 slots outward physically from the CPU, the green slots.  Do that with only three sticks now, and connect both the 24 pin cable and the 8 pin cable from your PSU.   

Be sure you use a 8 pin cable labeled ATX EPS or CPU from the PSU, and not an 8 PIN that is meant for graphics cards.    If your PSU does not have an 8 pin for the CPU it will have a 4 pin instead, one of those must be connected along with the 24 pin.

Okey, I installed only three ram memories in the Green slots, the 24 pin connector is conncted and I used an 8 pin conector labeled "+12v MB" for the cpu. I also have an amd 6990 installed with both 8 pins connectors connected with a PCIE cable. It still doesnt work :'(. Thanks a ton for the reply!

PS: by psu plug I mean the power cable between the wall's outlet and the psu

Ahh ok on the PSU!   Sounds like you have it all setup correctly, no error beeps, or do you not have a case speaker connected?  If you do not have a speaker connected please connect one.

What CPU are you using?  

Does the board stay running, or does it cycle on / off quickly?  Please try connecting the 8 pin CPU connector to the lower 8 pin connector on the board, if you have it in the upper one now.

If none of that helps, you may need to remove the CPU and check to make sure there are NO bent CPU socket pins, if a single one is bent or broken the board might not start.  << Wait on this until you tell me about the CPU you are trying, in case it's just the CPU might not be compatible with the BIOS installed.  If this is the case, do you have or can you borrow an older CPU from somewhere like 920-920?

Was this all new, or did you buy used?

Also, before you try anything else!   Please try clearing the CMOS.   Unplug the power supply from the wall, or switch it off, then press and hold the case power on button for one minute.  Then short the Clear CMOS pins for a minute, then remove the short and turn the power supply back on and see if it will start then.

And remove ALL hard drives, CD/DVD drives, and anything else you have connected like USB hubs, printers, ect.  As any one of those things if bad can cause the board to not start.

Hi

If this is an upgrade as opposed to a new build it is quite possible that you have left an old motherboard stand that should have been removed and is causing a short to earth. So the first thing is to check that there are no shorts. If necessary remove the motherboard from the case and build it outside on the bench.

Make sure that you observe anti-static precautions.

Lay some cardboard or use the motherboard box that is non-conductive on the worktop and remove the motherboard/CPU/heatsink/fan/buzzer/one stick of memory/graphics card and PSU from the case and put it on the cardboard. Add the keyboard and mouse and try and boot. The system should try and make a beep or series of beeps. Please post what sounds it makes.

Please post a list of your components especially the PSU make and model.

disconnected everything but the cpu's 8 pin connector, cleared the cmos and i still get nothing. The only thing i have after hiting the power button are those two leds (orange ane green), nothing else (the fans dont even move 1mm)

PS: i have an intel core i7 980x
Title: Re: Computer wont even start!
Post by: Lsdmeasap on March 08, 2012, 10:01:24 am
980X is supported from BIOS F1, so that's not the issue.

You either have a short as Dark Mantis mentioned, or you have bent CPU socket pins.   Test OFF the motherboard try on a wood table or box as mentioned above, then if that does not help you'll need to check the CPU socket for bent pins.

Is this all old, new, or what?  Please when you list your hardware tell us what is new and what is old, and what you KNOW for sure works such as memory from older build, ect.

Title: Re: Computer wont even start!
Post by: Dark Mantis on March 08, 2012, 10:10:02 am
The other thing is that possibly the PSU isn't powerful enough to run the system now.

Everything is new, here is a list:

intel core i7 980x
wd velociraptor hdd
amd radeon 6990
patriot g2 ram 8gb ram memory

Then you probably have a short, or bent CPU socket pins.  Please find a case speaker and connect and try once more before you tear it apart, in case it gives us an obvious error that does not require a tear down.
Title: Re: Computer wont even start!
Post by: Kren on March 08, 2012, 10:29:09 am
it has to be a two pin case speaker or can i use a regular one attached to the miniplug audio output?
Title: Re: Computer wont even start!
Post by: Lsdmeasap on March 08, 2012, 10:32:32 am
Is has to be the 2 pin case speaker, connected to the motherboard which is a 4 pin header with two missing in the middle

Looks like this

Yes I do wish they would start including them in with the motherboard bundle again.
Title: Re: Computer wont even start!
Post by: Lsdmeasap on March 08, 2012, 10:58:37 am
It would be nice, but I haven't seen that for years, you either get them with a case or buy on the cheap elsewhere
Title: Re: Computer wont even start!
Post by: Dark Mantis on March 08, 2012, 04:05:59 pm
No, they seem to have disappeared in some cost cutting along the way. At one time the case manufacturer used to supply them but that was generally when they were in the actual moving coil speaker format as they changed over to solid state devices the motherboard manufacturer took over the supply but then they seemed to think we could do without them.  :-\

Post by: Kren on March 08, 2012, 06:33:54 pm
Well, i bought a case speaker today and nothing, not even a single beep... only those 2 leds. I already took the cpu away to check the pin connectors and they are all good. Any ideas?
Title: Re: Computer wont even start!
Post by: Dark Mantis on March 08, 2012, 06:41:03 pm
If you have purchased a solid state beeper like Lsdmeasap shows then it is polarity conscious, in other words it will only function one way around.
Title: Re: Computer wont even start!
Post by: Kren on March 08, 2012, 09:27:34 pm
I bought the exact same speaker lsdmeasap posted. Tried both ways and still nothing. It goes with the "Speaker" labeled part downside, right?
Title: Re: Computer wont even start!
Post by: Dark Mantis on March 09, 2012, 10:01:28 am
Not necessarilly, but usually there is a small + printed on the plastic of the circular buzzer denoting the positive cable. Failing that there might be a triangle stamped on the connector above the positive side.

Be sure you are connecting it to the correct place on the header

If you are, and there is no beeps, then you need to remove the board from the case and get it OFF the motherboard tray, then test it on a wooden table or cardboard box.   If no luck there, then you need to show us some images of your CPU socket, please take these in a well lit room with no flash.  Use Macro mode on your camera and take the images from an angle, and do not zoom in too close.

And if you can, test booting with your memory and graphics card in another computer to be sure those are all working.

Well, the weirdest thing just happened... After reconnecting everything I tried to power it up again, and guess what... it went BOOOOM! one of the psu's capacitors exploded. I'm thinking that the psu was bad from the beginning. I'm going to buy a new one and keep you guys up to date! Thank you sooooooo much for your replys!!!
Title: Re: Computer wont even start!
Post by: Lsdmeasap on March 10, 2012, 06:06:44 am
Ouch!  Terrible to hear, hopefully ONLY the PSU was damaged!   Ultra does have a quick RMA service, but they like to charge you card while they wait on the faulty one to arrive, but sometimes they ship out a new one with no hassles.

Please try to find a friend or family member, who will let you test or test for you, so you can test your CPU and memory to be sure they did not get fried.   Also, if you can test your board somewhere too just to be sure it's OK
Title: Re: Computer wont even start!
Post by: Dark Mantis on March 10, 2012, 08:04:44 am
Yes, I would agree with Lsdmeasap in as much as more often than not if the PSU goes tits up it usually takes some other components with it. Pain, but that is the way it is. That is why we always advise purchasing a good quality PSU from a respected manufacturer. :-\

I like Ultra Power supplies, but only certain models and series.   Like X7 750W, or X3 any model 750-1000+

Still rocking X3 850W here and I push it HARD!!  X4 series look very cheaply made, and the last review I looked at for them by JohnnyGuru said about the same I believe
