Windows 7: Many BSOD - mostly at bootup

09 Sep 2013   #1

Windows 7 Home Premium 64bit
Many BSOD - mostly at bootup


For several weeks I have been getting the BSOD. They have been mostly during bootup, but some have occurred a long time after bootup. I believe the first one I received had BCCode 1E, but since then I have had several different codes. Hopefully that will be reflected in the dumps I have attached.
Attachment 285205
I have tried lots of things to fix the problem, but nothing has worked. I have:
- used restore points from a few moths earlier.
- run CHKDSK
- run sfc /scanow
- run Virus scanner
- run a Microsoft Memory Diagnostic.
- updated driver RTL8192su.sys, which was mentioned in several crashes.

Also, in at least one crash "ntfs.sys" was mentioned. My understanding is that this would normally be updated by the Windows 7 Update procedure. Currently it is at version 6.1.7601.18127. I note there are later versions on the Microsoft site but from what I could tell the revisions were for systems used as servers. Hence I have not tried to update this file.

Everytime I tried to boot in "Safe Mode with Network", my PC crashed. Safe Mode by itself seems OK.

Hope someone can help.

To start off:

Probably caused by : RTL8192su.sys
This has been popping up in most of the dump files. Try making sure your Realtek Drivers are completely updated.

Probably caused by : hardware_disk
To be safe run a hardware check:


BugCheck 0x124

warning   Warning
Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. WARNING: The steps that follow can void your warranty!!!

For your hardware stop 0x124 crash, read through Stop 0x124 - what it means and what to try and use the following hardware checks to supplement that link.
  • If you are overclocking any hardware, please stop.

  • If you have an SSD, make sure the following are up to date:
    • SSD firmware
    • BIOS Version
    • Chipset Drivers
    • Hard disk controller drivers/SATA drivers
    • If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.

  • Run all but the advanced tests with SeaTools for HDDs.
    SeaTools for Windows

    SeaTools for DOS
  • Monitor temperatures during the following tests.
    Use the following programs to monitor the temperatures.
  • Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).

    For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
    1. Shut down and turn off your computer.
    2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
    3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
    4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
    Once these steps have been followed, it is safe to remove and replace components within your computer.

Windows 7 Home Premium 64bit
reply to HonorGamer

Thanks Justin,

My hardware warranty is well and truly expired.
It's worth mentioning that I have 2 bootup options. Both Windows 7 Home Premium, but one is 64 bit the other is 32 bit.

It's just the 64 bit version that has the BSOD. The hardware is almost the same for both versions.
Each version boots from a different HDD. The 32bit version can't access all the 6G memory.

When I ran the memory diagnostic (from CD) I ran it for several passes and then swapped the memory chips, because the diagnostic tool said it could only test 4G. Maybe the tool has been updated since I downloaded it a few years back. I ran the advanced test after swapping the mem chips.

Another difference is that the 32bit version does not have Windows 7 SP1. I spent days trying to get it to install without success and just gave up eventually. So I guess it could be something in SP1 that is causing the problems.

I do not have any SSDs.
So my current plan of attack is:
1. Check Realtek drivers other than the one I already updated.
2. Maybe restore to a point before SP1. Any thoughts on this?
3. Do hardware tests on the HDD which boots the 64 bit version of windows 7.

Thanks again.

I have not had a random BSOD for several reboots and about a day. So maybe that problem has been solved. I will monitor it for a few days to be sure.

The secondary problem has not been fixed and that is the BSOD that can be invoked at startup by selecting the "Safe Mode with Network" option. I think I should start a new post on that when I am sure the other problem is solved.

Post back ASAP if you get another BSOD. Along with the files.

Still getting crashes

I have updated drivers for Realtek, NVIDIA and Audio.

One of the problems I had before was that I got a BSOD whenever I chose "Safe Mode with N/W". That seems to have gone now. However, unless I boot in a "Safe Mode" it is not long before I get a BSOD.

Hence I have not been able to do the Hardware tests requested, since they will not work in Safe Mode.

I don't actually recall getting error 0x124. Most of them are 0x0a. The last one I got was 0x24 the previous one was 0x34.

I have attached a zip file.
Note: For the last few bootups, I have set "Diagnostic Mode" using msconfig. In otherwords, only MS Services are loaded and no startup programs are loaded (still crashes). One service I noticed listed is "Realtek11nSU", which would be one recently installed when I updated drivers. So it is currently disabled. I assume it is to regularly check for updates. Anyone know? When I did the install for RTL8192su.sys, Zone Alarm advised that "RTLService MFC Application is trying to communicate with C:\Wndose\System32\winlogon.exe by opening this process". I let it proceed. It also left a shortcut on the Desktop called: "Realtek 11n USB Wireless LAN Utility", which I have not tried opening.

More tests done

I have done significant memory tests without errors

I was able to run the SeaTools tests on the HDD from the 32 bit OS. Again no errors found.

Still Need Help Please

I have done many of the tests recommended.
The tests I have not done are the temperature related ones, because the system crashes too often and I doubt that testing from the 32 bit OS would be valid, because it never crashes. My feeling is that if it is a hardware problem it is most likely Memory or HDD. I have done all the HDD tests recommended and run Memory tests for well over 24 hours.

Two weeks ago, in post #6, I attached zipped dump files from that time. I have not modified my system since then and have avoided using the 64bit OS until today.

Today the system crashed at bootup. I have attached a zipped dump file with the suffix "A" in the file name. Not sure if it is complete since a crash occurred while creating the file. I had rebooted in "Safe Mode with N/W". When I next rebooted I used "Safe Mode" and created the attached zipped dump files with the suffix "B". This one is complete and the error message was different from the previous crash.

So far, I have never had a crash in "Safe Mode" but have had several crashes in "Safe Mode with N/W". Until today I believed I had solved this problem when I updated some of the drivers. Apparently not.

I would appreciate any assistance.
