Persistent BSOD and CTD problem

Hi. I've been having a persistent BSOD and CTD problem with my desktop PC for over a year now. It's getting to the point where it's unuseable.

I upgraded frmo Vista to Windows 7 in an attempt to resolve the issue, but sadly it's still there. I then went back and upgraded again as a 'fresh install' option, electing to remove all previous data, but even this didn't work.

Although interestingly, it's stored my previous data in a folder called 'Windows.old' which it won't let me delete, even though I have the admin (and only) account on the system. When I use cccleaner and similar programmes, it claims to fine registry problems in this folder which I'm unable to do anything about. Could this be the problem?

The pC is fine for general use, but the problem happens whenever I try to use it for gaming. I've scanned for malware using various utilities (I have AVG installed), updated the Direct X drivers, checked the video card drivers are up to date, checked for RAM errors, and checked my GPU and CPU temps (60 degrees, and up to 85 degress respectively).

Here's a BSOD message I had:

STOP 0x0000008E (0xC0000005, 0x91CDa6C4, 0xA752C500, 0x00000000)

dxgkrnl.sys - Address 91CDA6C4 base at 91CD80000, DateStamp 4ce78ffe

After this I ran the latest Direct X web installer, but I'm still getting both BSODs and CTDs.

I can provide my DXDiag info if that helps. Really grateful for any help, this has been going on too long!

When attaching dmp files, PLEASE put them in a single zipped folder

Hi Splendid Belt and Welcome to The Forum.

Usual causes:
Insufficient disk space, Device driver, Video card, BIOS, Breakpoint in startup without having a debugger attached, Hardware incompatibility, Faulty system service, 3rd party remote control, Memory.

Old and incompatible drivers can and do cause issues with Windows 7, often giving false error codes.
Random stop codes can often indicate hardware issues.

As a Priority:

As you can see, there are a lot of possible causes for a stop error 8E.

We really need to see the DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

To ensure minidumps are enabled:
Go to Start, in the Search Box type: sysdm.cpl, press Enter.
Under the Advanced tab, click on the Startup and Recovery Settings... button.
Ensure that Automatically restart is unchecked.
Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
OK your way out.
Reboot if changes have been made.

The .dmp files are located at C:\Windows\Minidump. Until a .dmp file is generated, the Minidump folder may not exist.

Go to your C:\Windows\Minidump folder. Copy the .dmp files to a new folder on your desktop. Zip up that folder and attach to a post.

Please see: How to ask for help with a BSOD problem Following Method 2:
and run the SF Diagnostics Tool. Right click the SF Diag tool and select Run as Administrator before running. When the reports have been created, zip them up and attach to a post.

Download and run CPU-Z. Take screenshots**/snips of the CPU tab, Mainboard tab, Memory tab and all the slot #'s under the SPD tab.
Go to Post Reply, click on the Go Advanced button and attach the screenshots**/snips to your post for all the RAM experts to see by using the paper clip you will find on the top toolbar. Do not zip them up.
If screenshots, please crop.

Thanks for the quick reply Elmer. I'll reply again with the requested info once I've had a chance to get it. Thanks again.


Here are the pics taken from CPU-z, and the zipped up dump files and files from the diagnostic tool.

Thanks in advance for the help, and let me know if there's anything else I can provide.



Hi, did I provide all the info you need? Happy to dig around for more if it helps.

Thanks again,


Had lots more CTDs and a couple more BSODs lately. THe last BSOD had a different error code to normal. Here are the dumps.

Usual causes:
Insufficient disk space, Device driver, Video card, BIOS, Breakpoint in startup without having a debugger attached, Hardware incompatibility, Faulty system service, 3rd party remote control, Memory.

Your latest dump file lists dxgmms1.sys as the probable cause.
This is a Windows System file and for it to be the cause of your crash is highly unlikely.
Old and incompatible drivers can and do cause issues with Windows 7, often giving false error codes.
Random stop codes can often indicate hardware issues.

As a Priority:

AVG is known to be a cause of BSOD's on Windows 7 systems. Suggest that you uninstall it. Download the correct AVG Remover for your system (32 or 64 bit).
If you have AVG ID protection installed, download the AVGID Protection Remover from the above link as well (it wouldn't hurt to download and run it anyway). Download BSOD friendly Microsoft Security Essentials as AVG's replacement.
Uninstall AVG through the Control Panel. Re-boot to Safe Mode and run the AVG Removal tool(s). Re-boot to normal mode and install MSE. Make sure your Windows firewall is enabled! After your blue screens have been resolved, feel free to re-try AVG.

Drivers with Updates:

Rt86win7.sys Thu Feb 26 09:04:22 2009 Realtek PCIe GBE Family Controller v7.050 If you're unsure about manually installing drivers then choose the Win7 and WinServer 2008 R2 Auto Installation Program (SID:1477671) option to download.

Let us know how it goes. If you get further problems with blue screens, attach your new dump files and details and we'll move on from there.


Thanks for the response Elmer. I updated the driver, but had another BSOD within 10 mins unfortunately.

I can uninstall AVG, but I was getting these issues even in the two weeks when I didn't have it installed, after deleting everything and upgrading to Windows 7.

I've attached the new dump from just now, it was the driver irql less or not equal error.

Thanks in advance again.

Would appreciate removing AVG, at least until you settle down.

Can you adjust your RAM timings in the BIOS from 5-5-5-15 to 5-5-5-18

I uninstalled AVG. By the way, I got this report from Windows, which I'm sure is very much advice for beginners, but I'm posting it here in case it's useful:

"Microsoft is unable to determine the exact cause of this error. However, this problem was most likely caused by an error in your computer’s random access memory (RAM). RAM is the main internal storage area the computer uses to run programs and store data.

During the crash analysis, we noticed the basic input/output system (BIOS) version on this computer does not match the specifications for the central processing unit (CPU), also known as a processor, that is installed on your computer. This can occur when a newer processor is installed on an older system board or older BIOS. Using a BIOS that does not support the installed processor can result in Windows system crashes."

I'll change the RAM settings now.

Sorry to be so dense, but I can't see how to adjust RAM timings in my BIOS - I've been through all the possible settings and I can't see it.

Would you recommend updating my BIOS to the newer version?

Have a look at the reasons its been updated. See if you've had any of the "issues" the updates address.

I downloaded the MSI 'Live Update' programme to update the BIOS. It scanned my system, and showed me the BIOS update I needed. Downloaded it fine, but then the programme stops working each time I try to go to the next step. And when I find the BIOS update files it downloaded, the executable does nothing.

The update doesn't specifically talk about stability issues, but mentioned CPU code fixes. The fact that I've wiped this system and upgraded to a new OS and still got the same problem makes me think it could well be a BIOS, or other underlying issue.

But right now I'm stuck at the stage of apparently being unable to update my BIOS, and also being unable to change my RAM settings as you previously suggested.

Well. I had a look at a manual for your MoBo and have to admit it's lost me!! Not the clearest (to me) of manuals to find the ram timings.

The update doesn't specifically talk about stability issues, but mentioned CPU code fixes. The fact that I've wiped this system and upgraded to a new OS and still got the same problem makes me think it could well be a BIOS, or other underlying issue.
I think that MS pretty much got it right with their response to you. Hoping someone who is more into BIOS settings than I takes a look. This is the manual I downloaded. Think I got the right board!

Thanks again for this Elmer. Would you recommend I take the PC to a specialist to get the BIOS upgraded? I'm worried about completely destroying it if I try myself...

I've had a further thought. I may be wrong, but I think the crashing problem started after I installed my current graphics card. The old one pretty much blew up whilst gaming, but I don't think the system used to crash at that point.

Not sure if that helps, but thought I'd mention it.

I can understand your 'nervousness' although updating bios is a lot easier these days than it was. For the price of taking it to a specialist you could most likely afford to upgrade your MoBo with a nice new one (well, near enough!!). Have you no-one you could ask who has updated their BIOS before who could help you?

My helpful IT guru friend moved to Denmark, unhelpfully. Seems I'm a bit stuck.


Extraordinary Member
I'm not going to say to you tht you should update your bios if you don't feel confident in doing so. And a quick look at the instructions seems to show the "old" method, as in, boot from floppy etc.. Nowadays you can just run from your system. PC re-boots. Voila!! Updated bios (that's the simplified version!!).

Has AVG been removed (still showing on last dump file)?
