Weird power up problem in new system *Updated - Memtest complete*

Just built my new system. Specs are:


Asus P67 Sabertooth Mobo
i7 2600k 3.4GHz
Asus HD6950 Direct CU II
16GB Corsair XMS3 DDR3 (thanks to help in previous thread re changing to this memory!!)
Cooled with a Coolermaster CMV6GT

PSU is Enermax Galaxy EGX1000
Using one DVD R/W, one Samsung 1tb SATA drive and one older 80GB WD Raptor SATA drive.


I built yesterday, had two random lock ups. No BSOD, no anything....just total freeze.

Secondly, when powering up, the power comes on for about 4 seconds, turns off for about 2 seconds, then comes back on again. It does this every time I power up. It also does it when pressing reset button - just powers off then back on again.

Never come across this before. It wasnt doing it before chaning the hardware.

I have the DVD drive and both HDDs running on the same power cable which has three power sockets on. 2x 8 pin connectors both attached to GFX card and both sets of power cables connected to mobo.

I did a brand new install of Windows 7 Ultimate (64bit obviosuly). Nothing overclocked (yet!) - just running vanilla at the moment.

Any ideas?

Well the only thing that concerns me is the above quote - the most obvious warning to me.. Have you tried disconnecting this 3-way psu cable and just plugging in your primary boot hard drive that the OS is installed (or going to be) on?

How far have you actually got with this new rig then - has it actually fully booted successfully? Have you got to booting the Windows install disc? Where does it freeze/lockup or provide the BSOD?
 
No not tried to boot without them all plugged in - Will give it a go tomorrow and see what happens. Hope it isnt that as I am trying to keep cabling to a minimum.

Yes it is fully up and running - using it now.

The random lock ups are just that - Totally random. It has only been 2 so far and ive just been on t'internet when they happened. No BSOD on either occasion, it just locks and is non responsive to any input.

Will post results of the power cable tomorrow - bit late to faff about in the case at this hour.
 
Ah well if it is fully installed but randomly locking up could well be a PSU issue, but I'm just concerned about the 3-way split lead into the DVD drive and 2x HDs.

But yeah, awesome, let us know tomorrow. :)
 
When it powers off then on again at start up this is normal, all asus motherboards do it, it's just a self test. Also try running memtest for half an hour or so, so we can rule memory out of the question.
 
Is this something new?

My previous three mobos have all been asus and none of them have done it, my most recent before this being a P5E3 Premium.

Good stuff if that is what it is :)

Will also run memtest tomorrow

As with power cable I know what you mean if ia just one lead with 3 sata plugs on it, this is normal and there is no need to change it.

You can disregard my comment earlier OP - reading Freddie's comment I've just realised what you've actually done. :o

I thought you'd actually just had 1 psu socket, bought a 3-way splitter and plugged that on to 1 connector.. You've actually just got the psu wire strip that branches off multiple SATA PSU connectors haven't you? My misunderstanding, apologies. ;)
 
Yeah its three seperate sockets on one original cable, not a splitter.

Just trying to work out how to use this memtest program.....got it onto a USB stick....cant find any instructions!
 
OK so had another random crash -

Ran memtest - Crashed.
Ran again - Lots of red - over 10,000 errors

I am now running again, but im only doing it with one memory module in at a time. Looks like its going to be 40mins to test each module, so in about 2.5 / 3hrs I should have full results, but definately does look like one or more of the RAM modules is fubared.

Anyone know if OC is open tomorrow to raise an RMA or will I have to wait until saturday?

Second point..... when I do RMA, is there any point in getting a replacement and sticking wih 16GB or even having 8GB on hand spare for the future, or should I just stick with 8GB and get a refund on the faulty stuff? Its a gaming PC, so I understand 6GB is enough, but with RAM being so cheap I went for the futureproofing option with this.


**UPDATE**

OK, didnt take as long as expected. I ran memtest on each module individually. I had one crash with one of them in, but on a second time of running it all came back fine, so 100% OK tests on all 4 modules individually.


Any Ideas?

Hmm...I don't like the sound of them errors on the secound run, have tried error checking the hard drive, this is what i would do after ram, just right click the drive in my computer then tools then error checking.

Well i've left the memchecker running will all 4 modules back on the board for the last 3 1/2 hours now - Its done two complete test cycles for all 4 moudles and passed with no errors, so christ knows what was going on when those errors came up.

Totally baffling. Hard drives next then - Would be suprised though, as never had a lock up / crashing problem on my old build, its only since upgrading.
 
Bit of an update...

It has just randomly reset itself whilst attempting to play COD4.

Im thinking it wont be HDD related.

So options now for me are PSU (seems like a slim chance I think, but could be), or there is a problem on mobo or graphics card causing it. Going to play a different game and see if there is issues once more load is placed on the gfx card.

I have got another gfx card still from my old machine, but it had a fault when it came out, so not sure I can really use that to test.

If I end up having to RMA the lot I will be very unpleased, especially as it came from two different places. Will see how this game test goes on Left 4 Dead 2
 
Great - Wont even let me play L4D2. Says something about the gfx card not being in the database, loads up the title screen, then just kicks me out.

Facepalm.

Not particularly new.

I've had several X38 and X48 Asus boards which did it.

Changing pretty much anything in the BIOS caused them to do this as a self test before booting "properly".
 
Got L4D2 working now.

verdict - Played all first campaign and as soon as the ene sequence started total power out and system reset, so I would say GFX card or PSU is the problem. If only my old card wasnt bust so I could test. I dont want to pay £100 for a new PSU just to find the gfx card is the problem.

Anyone live in county durham want to lend me a card to test?!

Grr things like this really pee me off.

Surveyor - Thanks for that. At least I know that isnt part of my issues now.

I assume you must have changed something in the BIOS for it to be doing the dual boot.

Your original post doesn't say anything about overclocking so what have you changed?

What voltage are you running the RAM at?
