BSOD Issues

#1
Hi,

I'm looking for some help with repeated BSOD issues I am getting on my desktop. I've looked through the 'how to ask for help with a BSOD problem' posts so hopefully I have attached all the right bits to his post, but do lt me know if I need to provide anything else.

Thanks in advance.

Hi,
looking through the dump files there over 12 different types of Bugcheck which in itself can sometimes be indicative of a hardware issue. The most frequent Bugchecks were ones relating to memory issues and you might well have some faulty RAM. The above dump file means a memory management error occurred.

McAfee was mentioned in quite a few dump files and is known on occasion to cause issues. Please uninstall and use MSE for the interim as it's super stable:
http://www.microsoft.com/en-gb/security/pc-security/mse.aspx

atikmdag.sys Thu Sep 12 03:08:03 2013: AMD GPU driver. Please update:
http://support.amd.com/en-us

Rt64win7.sys Mon Mar 22 09:57:14 2010: 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

I think your also missing a Realtek Hi-Def audio driver:
http://www.realtek.com.tw/downloads...=24&Level=4&Conn=3&DownTypeID=3&GetDown=false

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 overnight if possible 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 prompt reply. I've fololowed your suggestions and hope that resolves the issue. I've already run Memtest and my RAM passed the test on 7 runs. I understand that the next most likely hardware thats faulty would be the motherboard, but I'm hoping thats not the case.

Hi,

After following instructions my blue screens stopped happening. Over the las few days I have had another three though. I've attached the new files.

Is this likely to be a hardware issue?

Hi,
two of the dump files sent blamed memory and the other blamed the system kernel.
How long did you run Memtest86 for? It's best if you can run it for at least 12hrs as some errors don't appear until the 12th hour. Also try testing sticks individually first in one slot and then the other. If you find a stick errors out in one slot but not another then you know your slot is bad.

Just to cover all the bases please run a chkdsk too:

Check for system corruption by finding command prompt in the start menu, right click on it and run as admin. Type:
sfc /scannow
Press enter and await results.

Hi,

I had run memtest for over 12 hours and no errors cameup. I followed these other instructions and it seemed to find and correct some errors under the sytem corruption. Overall the frequency of the blue screens is significantly reduced from when i first posted here. however, its still occuring - I've attached the new files. Any further advice here?

Hi,
looking through your dump files in general I'd hazard that you still have some corruption in the system.

ctxusbm.sys Mon Sep 07 19:09:28 2009: Citrix ICA Client USB Monitor Driver please update if possible:
http://www.citrix.com/downloads.html

Similar to the System File Checker is the DISM Tool. This will, if possible, download files to repair missing or corrupt data. Open the admin command prompt as above and type:
DISM /Online /Cleanup-Image /RestoreHealth
Press enter and await results.

Post any new dump files
