Maximus formula no boot, all voltage lights

[mrapoc]

Hey all

Just moved my pc up to my aunts in the car, now we have a no booter.

No beeps, just all fans on, 10 secs or so then power off and power on rinse and repeat.

Tried without RAM or GPU so far, no beeps, just all the voltage LEDs light up

:S

Reseat the cpu and heatsink first. If not sounds like the psu.

I had a similar problem just a few hours ago. Turned out that the RAM came loose. Last thing I checked. It should've been the first thing I checked But I don't know anything else to do then what tinytomlogan said.

 

[deathwish]

have you reset the BIOS

 

[kup]

Depending on whether the case was laid flat or upright during the move it could have warped or cracked the motherboard if the heatsink is heavy and it got bumped/shaken too much in the car.

 

[tinytomlogan]

Sounds like CPU / PSU to me.

Deffo first thing is to take off the heatsink and take the cpu out, reseat and start again.

If its still iffy try a psu.

 

[llwyd]

Normal procedure mate, whip everything out of the case and set it up on a box with minimal components, reseat the CPU and heatsink, clear the BIOS and test the outputs on the PSU with a multimeter if you can get your hands on one, or another PSU.

 

[mrapoc]

ok some results for you.

I first off rest the bios, both using the switch and taking the battery out overnight, no change!

So I took everything out bar the motherboard, powered up, low and behold i get beeps! beeps glorious beeps!

So I try with just the ram in, no beeps other than the one saying no keyboard/hdd detected.

So I try the GPU, works fine, all displays ok...

So I then try putting fans back in, I get to about the 4th/5th motherboard header (for fans) and it happens again, as if that many fans kills it. Disconnect all fans and its happening again...I'll wait a bit and try again.

Sound like a dodgy PSU? i dont know if its anything to do with the power here, but the same cable im using on my pc is currently in the family pc and its working fine, perhaps I should try different cable/different socket? Just strange as if its dying over a certain load?

check that the 4/8 pin connector is in all the way, that the 24 pin is all the way in, and that the headers don't have any shorts on them. A bit of metal scrping may well cause a short.

What PSU are you using? I doubt its the load, unless you are using deltas.

 

[mrapoc]

Its a ocz gamextreme, from my first build a couple or so years back. 600w

The fans are just coolermaster 20cm x3, 1 12cm, 1 14cm

hrrmm

 

[mrapoc]

gonna rebuild out of the case today i reckon

bit by bit =/

i gotta figure out the culprit, tried a different socket/cable and it worked for a bit then pow, no more

 

[Diablo]

Put the mobo on a bit of cardboard, and work from there. Perhaps a screw has fallen down onto some pins or something. Good luck dude.

 

[mrapoc]

Got the motherboard out.

Same thing happens on and off with just the cpu and motherboard - on and off with the RAM in/out too

Tried the PSU in the other PC and its powering it as I speak ok.

Seems I can test pretty much everything in my aunts PC (staying there for the week) as its a Q6600 too, so maybe the next step is to swap the CPU over to this rig, see if its all ok, inevitably probably eventually pointing to the motherboard being the problem

 

[Diablo]

Swap the PSUs the other way so that her PSU powers yours.

 

[mrapoc]

doin

 

[mrapoc]

ok - same problem on and off

took the RAM out and running it in aunts with my psu too..

works fine so its not RAM or PSU.

Only thing stopping me saying the motherboard is dead is the CPU - ill collect my articlean and mx2 paste off mum today, take the cpu out and back in, see if it helps - if not ill try the cpu in aunt's pc..if it doesnt work its the cpu, if it does work i need a new motherboard..

 

[mrapoc]

Right got my CPU in the aunt's pc too, and its working, so thats ruled out the CPU, RAM and PSU as they are working fine in the other PC.

Looks like its the mainboard - anything I can check for on the motherboard to maybe fix it before saying its dead and getting a new one?

 

[kup]

Sounds like the weight of the heatsink did crack it.

 

[mrapoc]

hmm i dunno theres no physical evidence and it would sometimes boot, whereas other times not

is there anything else i can do other than blast all connections with can o' air?

 

[mrapoc]

Blasted all connections with can of air and did a general massive dust out. Reapplied thermal paste, resat heatsink, basically rebuilt everything for one last try - seems to be working now (touch wood)
