1187104 2011-03-17 21:47:00 You think I'd learn, I build a 1366 based pc when they were new and had no end of problems (faulty XFX motherboard). Now I've built a sandybridge machine and the trouble has started again.

The new PC randomly locks up, usually with digtal noise spewing out of the speakers. It can run all night stable or it can crash within minutes. I have also had it just turn off without warning. When it freezes there is no blue screen it just stops responding and displays whatever was on the screen at the time. I have had 1 bluescreen - 0x0000001e 0x000000 0x000000 0x000000 but not sure that's useful as it's the odd one out off the crashes.

Also if I leave it unattended and it goes into standby it will not wake up and has to be rebooted, all the crashes also corrupted windows.

Specs:
Gigabyte GA-P67A-UD4-B3
i5 2500K
8G DDR3 dual channel corsair RAM
Palit GTX460 x 2 in SLI
Ccorsair TX850 PSU
WD black 1 TB hdd

what I have tried so far:
Re-installed windows (twice!)
looked for new drivers from gigabyte
removed 2nd video card
updated audio driver from realtek site
Flashed BIOS from F1 to F2
Ran memtest overnight - no errors
Ran Prime 95 for an hour - 74 degree max temp and stable
Rand Furmark for ~ 30 mins, 82 degrees max temp
disabled GTX460's HD audio device

the motherboard CPU & RAM are all new, the rest was working fine on my old rig set up much the same as it is now. It's been suggested I disable onboard sound and see if that helps so that's my next step but I don't expect it to prove much. I'm also contemplating setting up XP on a spare drive to see if that runs more stable in an attempt to prove if it's software or hardware.

Any suggestions greatly appreciated, I'm about ready to spit the dummy and RMA this thing

1187105 2011-03-17 21:52:00 First thing I'd be doing is change the WD black 1 TB hdd -- There have been countless problems with the Black WD's.:2cents:

Personally I have had several fail on customers machines (new), or give all sorts of weird events, change them to blues and never had the problem return.

if you have a look at the reliability history, that may give a few more clues . Click Start, type in reli, open View reliability History - where theses been crashes or problems it will be listed, click on the red circle with white x and it will hopefully tell you what happened.

Wont work or give an accurate result :groan: You are changing two things, the HDD and software - if its all OK, which was the problem ?? Hard Drive or OS ???

Change one or the other - not both.

1187106 2011-03-17 22:07:00 Wasnt the P67 chipset, the chipset that was affected with this Sandybridge prob?? This uses a P67 chipset by the looks of it Speedy Gonzales (78)
1187107 2011-03-17 22:32:00 the -B3 is the new fixed version, I waited for that to build this dugimodo (138)
1187108 2011-03-17 22:33:00 They were all recalled, so by rights unless a person has the older versions it wont be a problem.

The problem according to several articles is on SATA ports 3-6 -so if you only used ports 1,2 then it wont be a problem.

The new Replacement boards have a version Code B3 As explained here (www.pcauthority.com.au).

Just checked on a new gigabyte H67 board I got for a build, its running fine, and is the New B3.

hmmm, good point. I wasnt considering the drive as a possibility as it's around 6 months old and what are the odds it decided to fail the week I built a new pc

also regarding reliabilty history, all it shows at this point is 4 instances of windows improperly shutdown - since re-install 2 days ago

1187110 2011-03-17 22:35:00 Oh ok then. Get this www.nirsoft.net

Install it / run it. What files are highlighted? It may also say what files are causing this crash

I'd still change it, even if you then install W7 on another drive.

I've had the Blacks fail anywhere from 1 day to 4 months.

If you change the drive and it still does it, at least you have eliminated it. Changing more than 1 thing at a time doesn't actually tell you what was the problem.

Ain't Fault finding fun :D

1187112 2011-03-17 22:46:00 The realtek drivers are probably worse than the Win7 audio driver.

Here, the realtek drivers were as bad as the ASUS audio drivers. Turn it right up, it sounded like the volume was only up 1/2 way

The Windows driver are actually louder than the manufacturer's drivers

I'll give it a whirl tonight or over the weekend but I am not expecting much, it only bluescreened once and that was prior to reinstalling windows.Usually it just freezes, completely locked up, so it's not getting to the bluescreen stage.
