New system teething problems

PureAppleJuice · 28 Jul 2011 at 20:08

Hello all,

I've assembled my new system (minus the new case, whacked it in an old one, sigh). So, everything is wired up and it looks ready to go, but upon pressing the power switch the PSU fan spins for all of half a second, then nothing, silence, and it won't spin the fin for that half a second unless the PSU has been off for a little while.

Any thoughts? I might be making some school boy errors here...

Sorry, what do you mean by standoffs? As in, mounted to the case correctly?

PureAppleJuice · 28 Jul 2011 at 20:17

Okay, it looks like it's mounted fine... The PSU makes a clicking sound just after the fan shuts off. Could it be shorting somewhere? I've had a look but can't see anything obvious!

Yep, they're all fine.

Is it worth taking the motherboard out of the case and powering it on using a screwdriver to see if that would work? Could be me crappy temporary case shorting it somewhere...

AMD Llano A-3850
Kingston HyperX Genesis 2x4gb
OCZ Vertex 30gb
WD Caviar Blue 500gb
XFX Core Edition 550W PSU
Gigabyte GA-A75M-UD2H AMD A75 Mobo.

Any suggestions as to what I should put the motherboard on if I take it out of the case? Unvarnished wood?

Right- Have taken it out. Same result, really odd. I'd assume dud motherboard? I'd be surprised if it was DOA and as always I was absolutely careful in handling it when taking it out of packaging i.e. discharging static elsewhere and so on.

I'm going to wait until my proper case comes, hopefully tomorrow and see if I get the same result, bizarrely leaving technology alone just... only occasionally... makes it work, haha.

Okay, tried it without any other components in. I.e. the set up consists of the motherboard, PSU, CPU and that's it. The system should still power on like that right? But alas, nothing.

RMA the motherboard?

PureAppleJuice · 28 Jul 2011 at 21:28

Nope, nothing! Time to RMA. Back to the drawing board, sigh!

PureAppleJuice · 28 Jul 2011 at 21:37

Thanks- hope OcUK sort it quickly cough hint hint for any staff who are reading

PureAppleJuice · 28 Jul 2011 at 22:22

Haha, yes, I have boxed my goodies away and shall try over the weekend, will RMA it on Monday methinks!

Is there anyway to check that it IS the motherboard not the PSU? Sadly I don't have another desktop to test with!

PureAppleJuice · 29 Jul 2011 at 21:13

Right- After receiving my case, set it all up. PSU fans don't even move. Anyway, tried the paper clip trick- nothing, guessing the PSU is a dud, not the motherboard. I'm just hoping that where I set the lot up that somehow the PSU didn't take the other components with it...

PureAppleJuice · 29 Jul 2011 at 21:43

Fun fun! Thanks for all your help Jordan97! I think I might pick up a cheap PSU from somewhere just to see if I'll need to RMA the motherboard too, sigh!

Update - It was the PSU. Bought a 'cheap' replacement one (which I've now lost the receipt for -.-) and the PC powered up fine. Time to RMA that pesky PSU.
