Chris_B Posted March 21, 2008 Report Share Posted March 21, 2008 Now, I've built a fair few PCs in my time, and so far they've all worked. Not this one. I've got an Intel Desktop Board DQ35JO, onto which I've stuck a SLACR Q6600 2.4Ghz, and two Kingston 2GB kits (listed as compatible on Kingston's site), a single SATA drive and an IDE DVD drive. Plugged it all in, plugged in the mains and got a green standby light, pressed the front panel power switch and all that happens is a red LED labelled AMT lights up, and theCPU and case fans spin for a fraction of a second. No beeps, no video output. Tried with 1 DIMM and no DIMM, unplugged the SATA and IDE, and USB keyboard and mouse. Still exactly the same (lack of) response. The CPU and RAM are compatible with the board, so the box should at least boot, unless I've got a duff component. I've got a PSU tester in the office, but I can't be bothered to make the 45 minute drive to go get it this weekend. Any ideas what's wrong with it?

Chris_B Posted March 21, 2008 Author Report Share Posted March 21, 2008 Oh, and it does respond to a >4sec power button press and go back into proper standby, so the board isn't completely dead, just not booting. It doesn't seem to ave an external speaker connector, so I guess it has an onboard beeper, and tere's definately no sound coming from it at all.

alexc Posted March 21, 2008 Report Share Posted March 21, 2008 Are you using an old PSU? How many plugs to the Mobo does it have? Link to comment Share on other sites More sharing options...
Chris_B Posted March 21, 2008 Author Report Share Posted March 21, 2008 Brand new Antec NSK case with 380w EarthPower PSU. It's got a 24-pin plus a 4-pin ATX12V conncetor, which is all the board takes. Link to comment Share on other sites More sharing options...

[/ QUOTE ] Ok, next place I would look is the order of the connectors from the case to the mobo, just to make sure they are all in the right place..

Chris_B Posted March 21, 2008 Author Report Share Posted March 21, 2008 Looks OK to me - unplugged all and tried with just front panel power switch. ATX12V only goes in one way, main PSU connector is likewise keyed so it only fits the one way round, everything else unplugged. Tried a BIOS reset. Tried removing / reseating the CPU. Nada.

byron13 Posted March 21, 2008 Report Share Posted March 21, 2008 Hmmm without bios beeps to decifer it's a hard one, me thinks you may have to check out the voltages coming out the PSU mate. You sure the "soft" power switch pins all good?? Link to comment Share on other sites More sharing options...

Chris_B Posted March 21, 2008 Author Report Share Posted March 21, 2008 Soft-power pins appear fine - if I unplug the front panel switch and short the relevant pins with a screwdriver, same effect as front button. I'd down to PSU, board, CPU and cooler, and one DIMM in channel A bank 0, and it just spins the fans for half a second and sits there. I did throw this spec together in 10 minutes on Wednesday, but I do know this board is compatible with SLACR processors and Kingston claim it's compatible with the KVR800D2N5K2 kits I'm using. It's very odd indeed. Link to comment Share on other sites More sharing options...
Chris_B Posted March 21, 2008 Author Report Share Posted March 21, 2008 HDD (WD1600AAJS) doesn't spin up when pressing the power switch - think it should be doing? Could be PSU fault, which is an arse, as it would mean the whole thing will have to be dismantled as the PSU came with the case. Sigh. Link to comment Share on other sites More sharing options...
nordberg Posted March 21, 2008 Report Share Posted March 21, 2008 The HDD would spin up regardless of any problems with the mobo. I'd say your PSU is goosed. Link to comment Share on other sites More sharing options...

shark_90 Posted March 21, 2008 Report Share Posted March 21, 2008 Try unplugging the SATA connector on the HD and see if it spins up. It should spin on power-up regardless but it's good to check that there's no other factors. Link to comment Share on other sites More sharing options...
Chris_B Posted March 21, 2008 Author Report Share Posted March 21, 2008 I've had everything bar the mobo itself unplugged, and no joy. Then I remembered I had a huge Tagan sitting in the garage, and went to go find it. I let it warm up to house temperatures before trying it (don't want condensation inside a PSU!) and although it looks like it's just lost a fight with an octopus and a plate of spaghetti, it actually boots! I'll have to get a new PSU for it, as the Tagan is a little big and has too many cables floating about off it that will just get in the way. I might order another EarthPower 380W and just dump this one in the box when it arrives and send it back for a refund as DOA; beats returning the whole case. Thanks to everyone who had suggestionas to try - I was resigned ot it being a big problem, and your suggestions spurred me on to thinking about where I could get a PSU from and then I remembered the Tagan in the garage...

Thorburn Posted March 21, 2008 Report Share Posted March 21, 2008 I have to say my experience with Antec PSU's has been pretty damn poor, I'd avoid them now. The PC I built for Lottie had one and died after a few months, then the other day my media centre expired in a loud bang and lots of blue smoke. They make very nice cases, but I'd look elsewhere for power. Link to comment Share on other sites More sharing options...
Chris_B Posted March 21, 2008 Author Report Share Posted March 21, 2008 I got into an Antec habit, as I'd built a lot of PCs with them, and they'd been really good, but I've had a few die at well under a year old, and not heavily used, so yes they do seem to have gone downhill. Hmm, I might try to fit this Tagan in there; it's a little long and I'll have to squeeze the cables somewhere out of the way, but it's an option...

alexc Posted March 21, 2008 Report Share Posted March 21, 2008 I have to say I've had a few issues with faulty Antec PSUs, I've found OCZ,Thermaltake or Zalman to be very good but they're not cheap! Link to comment Share on other sites More sharing options...

nordberg Posted March 22, 2008 Report Share Posted March 22, 2008 Agree with the Antec coments. When we used to build PCs we used Antec cases and PSUs for a bit and had a load of trouble with them. Link to comment Share on other sites More sharing options...
ChrisT Posted March 22, 2008 Report Share Posted March 22, 2008 Same problem with Antec PSUs here. The 'boss' thought they were a good brand but we had 100% of the servers we fitted them with returned in under a year all with dead PSUs and some other damage caused by power issues. I would vote for Seasonic or Enermax myself. Link to comment Share on other sites More sharing options...

Waylander Posted March 22, 2008 Report Share Posted March 22, 2008 Oh crikey this doesn't make good reading. On of the reasons I settled on the Antec Sonata III case was because of the 500W Trupower PSU..... Link to comment Share on other sites More sharing options...

Paul Posted March 22, 2008 Report Share Posted March 22, 2008 Antec must have dropped their standards in the last couple of years then. Ive got a couple of years old truepower430 in my home built Pc, which is in daily use (On and off) and its been flawless. Link to comment Share on other sites More sharing options...

I had the same problems as you describe Chris, and it was my PSU that needed replacing. Link to comment Share on other sites More sharing options...
