New CPU/mobo, won't boot

Santa brought me an overclocked bundle, an Intel i3 540 3.06Ghz o/c to 4.2Ghz, 4GB RAM and a Gigabyte GA-H55M-UD2H (Socket 1156) motherboard. I already have an Enermax Galaxy 1000W PSU, a Gigabyte Geforce GTX 460 and a Logitech 510 USB keyboard.

Upon hooking up this lot (no drives, other cards or peripherals at this point), it powers up. For less than a second, when it then turns off. The fans (CPU, PSU, case and graphics card) start turning but quickly stop. I notice that the CPU fan doesn't actually get as far as rotating but it does attempt to before dying so it is getting power, it just sort of jolts before the juice dies. The motherboard's phase LEDs (whatever they are) all light up, as briefly as the other signs of life.

I have tried unplugging everything but the CPU and its fan. I've even removed the RAM and graphics card. I've cleared the CMOS, I've made sure nothing is shorting, I've checked, cleaned and rechecked the power connections. I don't have a spare PSU, memory or chip but the PSU worked fine yesterday and I tried another CPU fan.

There are no beeps, but my case's speaker is unreliable. I don't know if this mobo has a speaker on it, my previous one did but I gather most don't. I think this is failing before systems boot as far as beeping, although that's speculation.

What else can I try?

Where are you? I have a spare PSU you can try if your struggling.

My machine does that on start up, fans start spinning, then go off, then come back on. Never quite understood why it does it.
 
Eh, Londonderry, a bit far :)

I wouldn't mind if they did that, it's the third step that bothers me - them not turning on again. The whole system goes down, I was wondering if it is the chip. I could try reseating it, although messing with thermal paste does make me loose the will to live.

Why would the PSU die on me now?
 
Tried the mobo out of the case in case it is shorting out?
Got all the connectors to the mobo connected?4 or 8 pin for cpu.24 pin firmly pushed in
power connector to the gfx card?is it seated properly
if ram came separately,is it in the correct slots?
Few things off the top of my head :)
And re check again in the morning perhaps?as i have just noticed that you already have done this,fresh head so to speak
 
Well, if it did, it would be a massive coincidence. These things do happen though, and it is a possibility.

If you put your old board back in, and it boots, its not the power supply (call me Mr state the bloomin obvious lol)

I've read that each bundle sold gets individually tested, which I suppose cancels out the possibility it could be a dodgy bundle.

Not having any experience with a faulty chip I don't know what the symptoms are, but if you haven't fully fault tested, I guess you might have to bite the bullet and try it.
 
I've checked the power but I haven't triple checked the graphics card's power. I did get it out of the case. Trying the PSU on the old gear is a good idea, bit of a hassle but the "convenience" ship has sailed.
 
Yeah fault find with every spare bit of kit you have.

I always find it funny when people post replies to problems saying 'try testing kit x with spare part y'

Although certain people carry spares, I believe the vast majority of us don't have spare fully working 1KW PSU doing nothing in the wardrobe lol.
 
The PSU works on the old gear.

It does annoy me a bit when people wildly suggest trying another bit of hardware. I'm quite geeky so I have some bits and bobs but I don't have a spare Core i5 to stick in there or anything!
 
Ok so your PSU works with the old kit.

Also sorry if these are repeats of previous suggestions:

1. Take whole system out of case and test.
2. Ensure BOTH the 24pin and the 4/8pin connectors are firmly plugged in.
3. Test with just the motherboard/RAM/CPU - with that mobo you can still get video out.
4. Add back individual components and see if problem resumes at any point.
 
In these kind of situations, ask yourself whats changed. When everything you had before worked, whats changed.

The bundle you had.

So logic dictates its something to do with the bundle. If it was me, I'd email ocuk for technical support. Could be board, could be cpu, could be memory, but like we said, we don't have any of those sort of spares around the house eh.
 
Well, I've tried reseating the CPU. Same problem. I can't see what it could be except something being DOA.

How long do you think ocuk will take to respond at this time of year? I'm supposed to be getting work done!

Does the new motherboard use the same standoff placement? You don't have any extras in there or anything shorting it? I'd try a bench build myself (build and power it up outsde the case)
 
Do you have the ram in DDR3_1 and DDR3_3? Starting at the CPU that is slot 2 and 4. I don't know if the bundles come with the ram installed but your mobos manual shows that as what you should do. Also have you tried only one stick in (try both) in DDR3_1 (2nd slot from CPU)?

Sorry if you have tried all this, isn't clear if you have from the OP.
 
Yes I did try that and I checked the RAM positions. They are the other way around from what I'd expected so that was actually the first thing I checked.
 
When clearing CMOS take battery out and unplug mains, remove ram and leave like that for hour plus.

I had EXACTLY the problem you had with the same mobo. When I RMA'd it it came back tested as fine, and has been since. They are a little funky so bear with it. Also try to flash BIOS without the GTX in place and make sure on latest. Mine even decided to revert to an early BIOS at one stage
 
Hello, long time no see :)

I RMA'd it, they didn't specify what was changed but I assume the mobo as the ATX back-plate was sealed and I'd unwrapped the previous. It worked for the last week, until this morning. One lingering issue, the CPU fan doesn't start properly, sometimes it jerks on power-on but doesn't start spinning. Sometimes it will start a second later, sometimes I have to give it a nudge. I hope it will loosen up.

I had put the computer to sleep last night and I was woken up by the sound of it attempting to boot, failing, attempting to boot again a couple of seconds later. Yuck. I switched off the PSU and went back to bed, when I got up it took a few attempts to boot and then came up that the BIOS was corrupt because of an overclock or voltage issue, and that it had restored it from a built-in backup. Which means I've lost my overclock settings, including the profile OCUK put on. Grr.

If I continue to get any problems, I will try what you said Methanoid. I missed your post on the original issue as I'd given up by then and was in the process of RMA'ing it.
