BSOD Help Please

#1
Hi,

Hope someone can help.

Have got BSOD issue. Can't yet determine if a specific program causes it as it isn't regular except have had more than 4 crashes today. I read BSOD posting requirements and have attached zip file of files needed I hope.

Thanks,

Stephen

Hi,
most of your dump files are memory related and indeed the above Bugcheck means a severe Memory management error took place. Looking at your system though I see your Bios isn't up to date and several of the updates are stability related with one specifically for Memory stability.
BiosVersion = 1902
BiosReleaseDate = 04/12/2013
Latest update stands at version 2303:

Please ensure I have the correct motherboard and corresponding download.

Driver wise you could do with updating really but none seem desperately old.

aswRvrt.sys Thu Jun 26 12:35:39 2014: Avast AV known on occasion to cause the odd issue. Please uninstall to test and use MSE in the meantime as it's ultra stable:

iaStorA.sys Mon Apr 22 20:38:05 2013: Intel storage drivers. Please run the intel updater:

nvlddmkm.sys Fri Jun 21 10:06:16 2013: Nvidia GPU driver please update to latest whql:

Rt64win7.sys Mon Mar 04 07:25:55 2013: Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet please update:
http://www.realtek.com.tw/downloads...d=5&Level=5&Conn=4&DownTypeID=3&GetDown=false

RTKVHD64.sys Fri Mar 29 13:40:06 2013: Realtek High Definition Audio Function Driver please update:

If after making the above changes you still get the bsod then you need to test your RAM.
Windows does have it's own memory testing app but it can often miss errors and the best app for the job is Memtest86. The latest version of which can be found here:
http://www.memtest.org/

To run Memtest86 you need to either burn a copy of it to disk or use a USB stick. If you look down the page you'll eventually find the latest version and it's associated downloads. If your burning to disk choose the pre-compiled iso zip. If your using a USB method then the corresponding download is the auto installer for a USB stick.
Once you have Memtest86 on the media you selected you'll then need to enter your bios and change the boot order so that the machine will boot from either the disk or stick you have Memtest86 on.
Try and run the test for 12hrs min unless it becomes clear that there is a issue. If there is a problem with the RAM you'll see the errors pop up in red so you can't miss them.

Post any new dump files.

Thanks for your reply.

I am working my way through the updates you suggest but have a problem with the BIOS update. The PC was bought overclocked as standard. I've read about BIOS updates and I understand the overclocking aspect will be lost with a BIOS update and I shouldn't update the BIOS in an overclocked condition either.

Is the BIOS update necessary or could I leave that part out for now?

thanks and regards,

Stephen

Hi Stephen,
you might have a few options in this regard. Sometimes bios settings can be saved as a profile meaning you could reapply the profile after any update. Also usually pre-overclocked machines are sold by specialist manufacturers, do they have any tech support such as an online webpage with your models spec's ect?
Lastly you could always leave it as a last proposition. Try everything else on the list first and see how you go. Ideally though it's always best to be on the latest Bios (usually).

Hi,

I found the realtek driver updates almost impossible to fathom so left them alone. I spent a good hour or so trying to work them out but couldn't.

So I went on to the memtest which I had run before successfully but this time it failed instantly. Left it to run overnight. I have yet to do much reading on this subject. I'm assuming this now means I should isolate one of the RAM modules and repeat and then swap the other one over. Is that right? Is there anything that might point me to a dump file or result file?

cheers,

Stephen

Hi Stephen,
from what you wrote i see that Memtest86 had errors straight away? If this is the case then your options are based whether you bought the RAM as a matched set. If you did (as most of us do nowadays) then really there is little point in testing which stick it is as you'll be purchasing a new matched set anyway. Is the RAM used on the motherboard compatibility list? Might be worth checking....

As for the Realtek downloads. Using this link for the network driver:
http://www.realtek.com.tw/downloads...d=5&Level=5&Conn=4&DownTypeID=3&GetDown=false
The download you want is the second one down. Download it, unzip it and then run the set up exe found in the revealed folder.

Realtek Audio is the same. you want the second download down. I've given you a slightly different link although you may still need to click I accept the conditions box but see how you go:
http://www.realtek.com.tw/downloads...=24&Level=4&Conn=3&DownTypeID=3&GetDown=false
