Hey all, this is due to the aftermath of this thread (https://bitcointalk.org/index.php?topic=119013.0)

I plug everything back in, hit the power button and now my fans move about half a cm and then nothing happens.
dafuq did I do?

Any POST?

If not unplug everything. Then try booting with only one stick of ram if you get a valid POST then add the other stick if any. Then plug one component at the time an try to boot.

Good luck.

POST?

POST-Power-on self test.

So why did you start another thread?

http://en.wikipedia.org/wiki/Power-on_self-test

If you get 1 short beep when powering up, everything is good else you got a problem. Refer to your motherboard user manual for beep diagnostic code.

no beep
I'll take out GPU an shit, and see what happens

Probably one of your GPUs. Unplug them all from the MB then plug one in and make sure you see monitor output. repeat as needed.

This happened to me a few weeks back. It turns out my Power supply was failing out of a lead.

Removed my GPU, still nothing, I think i fried my MB

The fans spinning for a fraction of a second is almost always either a bad motherboard or a short wire somewhere.

Here is my troubleshooting procedures.
1. Unplug everything! Remove all cards
2. Check cpu/memory seated properly
3. Cycle switch on power supply, plug back in 24 pin motherboard/8 pin CPU/CPU FAN
4. plug in power switch on motherboard and check that it powers up (if not try different power supply and retry, if still no power replace motherboard)
5. plug in video cards 1 at a time and pcie cables (check pcie adapter cables if used sometimes pins come out of the molex side)
6. Check for power after each video card is added (if no power after a video card is added test motherboard again with just that video card or another system if possible to double check card is dead
7. plug back in drives and boot up system

#1 is important, unplugging cables will reset protection modes on power supply

Whatever you do, don't panic.

Disconnect all power leads except for those connected to the motherboard (24pin plus any extra 4 pin plugs).

As strange as it sounds, sometimes a fan might fail and it shorts causing strange behavior throughout the system. (Including no POST)

If you pull out all cards and leave the system as if it were a barebone, then you should know if it is the motherboard. Also retrace the steps you might have done in the last 24 hours. Usually it might be something pligged in badly.

unplugged everything, took out GPU and RAM, still nothing...

You need a minimum of 1 stick of RAM to boot  ;D

well yea, hang on, I'll take a pic of what I have plugged in ATM

Try this, (*maybe someone else already suggested this) unplug your power supply from the wall and then remove your CMOS battery. leave it for a few minutes. put the CMOS back in and power back up.

Do you know the model number of your motherboard? some models don't beep when they POST.

wait... how many GPUs on this rig? you only have one? do you have any other GPUs to test with?

just the one
its a GA-X58A-UD3R

Epicblood go down my list and tell me where you get stuck and I will be glad to help you. You may get bombarded with replies here and doing them in the incorrect order may not tell us for sure what the issue is

I have tried everything short of replacing parts (don't have any extras)

so you have no power on step 4 and no other power supplies to try?

nope, well I have another one, but its a broken one xD

^This!

Make sure there isn't anything shorting anywhere.  ...this includes BEHIND the motherboard against the case.  Check for screws or anything else metallic behind the board.

well then the only last thing I can suggest if you feel capable you can test power supply without it connected to anything by shorting out PS-on pin to ground and testing the voltage with a multi meter but its more than likely the motherboard but that would be the only way to know for sure without another power supply to test

fan twitch with no POST is a dead short somewhere, the PSU is crowbaring to protect itself

build the system up outside the case in a minimum config...nothing but PSU, MOBO, CPU, VGA, and 1 stick of RAM, report back POST or no POST

This has been suggested a few time already, same thing

Yeah its a short which makes it one of the harder things to diagnose. Your vrm's on your motherboard or video card can be stuck open causing it to look like a short. Running more than one gpu on each power supply lead can even cause shorts in the wiring itself from damaging the connectors. Fallen screws can cause shorts. Who knows what else could have happened? So if you could borrow another power supply that's the best solution. Honestly I think its best to have an extra one around just in case. A high quality 400w power supply should only cost you 40 dollars or so and the nice thing is it can save you from having a down system

yes, I see, thanks

has he built it outside the case yet?

Make sure you have sound connected to the motherboard to hear if it posts cuz sometimes that could be a problem.

I had that happened to me, it would power one, fans move once and then everything stops. In my case my CPU died.
If motherboard is dead it wouldn't even turn anything on and wouldn't have a light on it.
If RAM is dead, the CPU fan would still be spinning. Also if its a power supply test it with the paper clip by itself.

No fans, not even CPU fan, no beeps, no screen, just a the CLR button is lit

Have you tried booting without the GPU?

yea

You skipped this.  Your pictures look like the board is still in the case.  Have you taken it out and ran it yet?

just tried that, still nada

Hm, you wrote in your first post about how your fan just spin a bit, and I thought you may have same problem as I did.

Sorry to say, but your fans look nasty, blow some compressed air through fans. Sometimes dust on motherboard itself can cause a short circuit.

does your motherboard even have an onboard gpu?  My motherboard normally won't post without a GPU in there.

FWIW I had the same thing happen to me after a motherboard died.  Do you have anyone else's computer that you could test your PSU or GPU in?  I would short my PSU pins like superfastkyle suggested to rule out PSU issue.  Then it has to be the motherboard.  It's unlikely your ram would completely die.

Dude, not to bust your chops, but why in the world would you even waste your time mining with an Nvidia GTX 465?  At most you're getting what, maybe 70 MH for 350-400 watts of power?  For about .7 BTC ($8.50) a month, even at good power costs of .10 kwh, you'd pay $25 in power costs.

So, you're losing $17 a month, not to mention risking killing your gear, which I think you've found out ;)

Regardless, try another PSU if you have one lying around to see if it's the PSU or mobo.

Just had my friend come over who is a complete hardware junkie, I def need a new motherboard :/
Was gunna buy a new rig anyway, might as well be out of necessity I guess :p

Maybe once I get my bitcoin games site up, I can make enough BTCBTC to pay for it all xD

I bought the GPU way before I started mining, that was my gaming PC xD

Had similar problem fans moving just a tad, and a click from the PSU nothing else.
 Apparently It was my power supply Antec TP 650. A coil was shorting inside, apparently enamel had worn off where some glue on the coil has burned and was causing a short. Scraped off the carbonized glue and it started working again.

your buddy, he paperclipped the PSU and it fired up OK?

(short pin 5 to ground)

I checked the PSU and it is fine

Agree, seems like a RAM misplaced or defective !

RAM is fine, ill get a new mobo an see what happens.

ram is in the right slot ?  slot 0 or 1, does this ram work in pairs ?

yeah, sounds like a VREG failed on the MOBO

bummer man, hope you learned something though

unplug the PSU from wallpower and hold the power switch on the mobo for a few seconds.

then unplug the psu from the mobo and let it all sit for a few minutes then give it a try.

That capacitor on photo 3hn, just where the yellow wires come out of the black wrapping, is it still attached to the board? You did attach a power lead to the vid. card (assuming that it needs one)?

That capacitor seems to be connected to the PSU, no idea why

that one;

http://i6.photobucket.com/albums/y215/daargaje/3hn.jpg

yes that one

BIZARRE  it seems to be across the 8pin 12V plug

new one on me

I can't be from the psu, psu's don't have capacitors sticking outside the casing. I was asking coz that c. is in a rather strange position, stressed by the yellow cable's wrap.
If that is a red led burning, just above the blue "ultra" thingy, there is still power on the board (psu standby power?) I hope you did not change memory or vid.cards while this light was on, you might have had something shorted.

I had a similar issue once upon a time.

Everything was working fine until I tied the cables back. Then wouldn't boot, just a quick spike of power, then nothing.

I checked all the connections, they seemed connected, I swapped the PSU out and the new PSU worked fine.

Gigabyte motherboards are pretty rock solid. My guess is that there is a lose wire somewhere in the PSU.

Budget $20-30 Chinese PSUs don't last long, get a decent one if you plan to mine bitcoins.

Also get a can of compressed air and blow that dust out of the CPU heatsink!
It might be like that inside the GPU and PSU too which would explain your overheating issue! :o

I made sure there was 0 power on board when I changed things (unplugged cable and waited a minute). And that capacitor is firmly attached to the psu cord. And it might be the psu, but I don't see how it could have shorted between me shutting down computer and unplugging it. (Remained unplugged entire time I was rue arranging wires)
