Another BSOD to analyse...

Hi all,
I've just finished building a new machine and installed Windows 7 Ultimate 64 bit. I keep getting BSODs at seemingly random intervals - the machine will sometimes run all morning fine and then suffer bluescreens within minutes of rebooting. They seem to be related to heavy network traffic, although when I spent a morning downloading applications etc I had no problems :confused:

You'll find my dump files and health report attached.

Hardware:

Gigabyte GA-H55M-S2
Intel i5 750 2.66GHz
2x 2GB DDR3 1333MHz OCZ Gold RAM
500GB Seagate Barracuda
NVIDIA 9500GT

As I had a spare XP license and an upgrade license for Windows 7 is available with student discount, I installed XP first and then did a "clean install" upgrade to Windows 7.

I've run memtest86 for 12 hours (about 20 passes) and it reported one error of 1 bit on the 4th pass only.

I hope someone can help as I'm now stuck!

EDIT: Attachment didn't work. Fixed now!

Welcome to SF!

I suspect you are on to something when you suspect network. Avast is blamed by one dump, your Realtek drivers by another.

Please remove Avast with this tool: http://files.avast.com/files/eng/aswclear5.exe

Replace it with MSE: http://www.microsoft.com/security_essentials

If the problem persists, please follow the BSOD Posting Instructions again.

I've removed Avast, however, it now bluescreens when completing the final stages of MSE installation - every time. I've unplugged the network cable for now and am posting this from my Linux box.

More memory dumps etc attached - including the ones posted before.

Uninstall your Realtek network adapter drivers, as they are blamed by your last dump, and seem to have some error in msinfo32.

Install these ones: Realtek

The installer for the drivers you linked to caused a bluescreen, so I downloaded the drivers only and installed them through Device Manager. MSE has now installed successfully.
Memory dump from installer bluescreen attached.

Is it worth running Driver Verifier to see if anything shows up?

Let's wait and see if the bluescreens continue. If they do, enable driver verifier.

Well, updating the Realtek drivers seems to have solved the problem - it's been running all day and I've been using it with no problems.
If it does crash again I'll post again with the dumps for you.

Unfortunately, I return...

I was attempting to install Adobe Reader but launching the installer caused another bluescreen, blaming dxgmms1.sys - something to do with DirectX I think.

I rebooted, and the installer ran fine, but I thought I'd just post the dump here in case there's something else going on I'm unaware of.

Do you have another graphics card you can test out? I almost suspect bad video RAM.

If not, I suggest returning the card back to the place you bought it, and get a new one.

It may also pay to do a RAM test. See this tutorial: http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html

I've already run Memtest86+ - see my OP for the results.

The only other PCI-e video card I've got is an ATI Radeon HD5770 - it needs its own power connection, the PSU in the new machine hasn't got one/it's all zip tied tidily away somewhere.
The 9500GT I've got in here is the only non-new component - it's about a year old and was previously in my other desktop. I upgraded to the aforementioned HD5770 and decide to use the then spare 9500GT in this otherwise new build.
Meh. I'm tempted to not do anything and see if the problem happens again. Is there any way of doing the equivalent of a Memtest86 on video RAM?

Unfortunately I return.

The machine bluescreened again just now. I was just browsing the Internet. Is this the same issue as before or something else? Memory dumps attached.

The Furmark test ran fine; I quit it when the temperature levelled out.

I'd really like to see that other video card tested out. Any chance you could crack open that bunch of power cables?

Hi again.
Having now had some more time, I'm now continuing the troubleshooting.
The previous graphics card died, so has been replaced with a brand new one, no improvements. The PSU has also been swapped out for a slightly more powerful one, with no effect.
I'm going to run Memtest86+ again overnight, but in the meantime I've attached memory dumps going all the way back to my OP.

Hello again,

I see several possible causes, just from the dumps dated November and later.

First, your original theory of a network issue is not eliminated from this batch of dumps. Rt64win7.sys and NETIO.SYS are blamed by two dumps, which are your Realtek Ethernet and Windows networking drivers, respectively. Chrome.exe was the top process in another dump. Try installing these updated drivers:
Realtek

The next cause is your Hauppauge TV card drivers. Try installing newer ones from here: Hauppauge Computer Works : Support
Code:
HCW71364.sys    Fri Jan 15 15:20:45 2010 (4B50CE1D)
If you can't find newer ones, remove the device.

Do run the memory test again. One thing I missed the last time around was that error that was detected; any errors are unacceptable, and should be dealt with.

Beside the Memtest86 test, run Prime95. Run both the Blend and Small FFTs tests: http://www.sevenforums.com/tutorials/100352-cpu-stress-test-prime95.html

Also test your hard drive, with SeaTools.

Finally, let me ask, when did you replace the graphics card? Was it before or after November 5?

Hi,
Memtest reported 66 errors over 20 passes of the whole lot of RAM, so I'm now trying each stick in each channel in order to (hopefully) pinpoint the problem.

I've already tested the hard drive with SeaTools - it's fine.

The graphics card was replaced with a temporary one on 30/12/10, and replaced again with a permanent replacement on 8/1/11.

I'll let you know when I've pinpointed the RAM problem.

That sounds good.

Remember, modern boards usually run in dual or even triple channel configurations. If you need to RMA one stick, RMA the whole kit, to make sure you don't have problems down the road from now.

After a day of Memtest'ing, I've pinpointed the fault to one memory module. I've raised an RMA request with OCZ and am awaiting developments.
