Windows 7: Experiencing Random BSODs, error 0x00000050

09 Sep 2012   #11

Windows 7 x64 SP1

I did do a system restore when this all first started happening 2 weeks ago. It didn't fix things then. However, I will do one now and see if it works. After I do the system restore should I be able to put my other ram back?

Updated cpuz.

Thanks for the tip about memtest86+. Good to know for future testing.

I have a few questions:

1. You mentioned the SFC scan is the most important part. But I only was able to run it from w/in Windows. Does this make a difference? I know if there were files it needed to correct but that windows was currently using it wouldn't have been able to fix them.

2. Since pulling out the RAM in slots 1 and 3 my system has been stable and I haven't had any BSODs. If this is the case is a clean/repair install necessary or do you think the RAM is not the cause of the problem?

3. You said to only have slots 2 and 4 filled if I do the clean/repair install. If I do would I be able to fill the others afterward? After confirming it's stable.

4. Would uninstalling and reinstalling Norton be good enough? Just curious. Happy to use MSE for a bit if necessary.

5. You mentioned that many of the errors where processor related. Are you suggesting that my CPU is failing?

Do you have an earlier restore point than the last one?
If you do then try it.

After any fixes you try, run with only two RAM cards installed for a while, if it's stable add the other two RAM cards.

1. Did you re-boot after each SFC run?
A re-boot will repair any files that were running while the SFC scan was ran.

2. This is the second most important issue, we can work on this after your OS files errors are fixed.
If you try fixing the RAM issue now, we can't be sure if the OS errors are causing problems.
After the Restore/Repair/Clean install, and all the Windows updates are installed, drivers loaded (if needed), when the system is stable with two RAM cards installed, you can install the remaining two RAM cards and we can adjust settings if needed.

3. Yes, see my comments in #2.

4. There are known Norton issues with some Windows 7 systems, when trying to find what is causing system crashes it is best to remove as many possible causes as we can. Your dump file showed that Norton was an Unloaded module, which means there is an issue with it.
You should uninstall Norton, then run the Norton uninstall/removal app from Symantec, then install MSE.
Any program that we remove can be re-installed after your system is stable. Install one at a time and test for stability before installing another.

5. Could be corrupt drivers, IMC (Integrated Memory Controller) issue cause by the RAM not running correctly, or a faulty CPU.
More likely one or both of the first two.
If issues persist after fixing the OS and RAM issues then we can test the CPU.

You motherboard manual:
P55H-CM (V1.0)

Ram info from page 12, confirming what you have stated. But, you should be able to test one RAM card in slot #4.
FYI, if you need to test RAM again.

I well I tried a restore pt prior to Sept 5th. which is when the issue came back. It when through the process fine then shut down. When it rebooted it POSTed then let me pick my OS from the dualboot screen as normal. After that it said windows failed to started and I could choose b/w startup repair and start windows normally. I chose startup repair. Startup repair did its thing and completed successfully. I then went and redid all the updates you had told me to do (discwizard and cpuz).

I can look for a restore point further back if you think that I should. One before it first happened.

1. I did not reboot after each SFC run. I didn't realize I was supposed to. Should I try running them again and reboot after each?

2. That makes sense. Sorry for being so persistent about it. I'm much more experienced with hardware then software so I tend to think in those veins when troubleshooting.

4. Okay I'll uninstall Norton for the moment.

5. Good to know and glad you were able to confirm it.

So I see to main options at the moment, try and even earlier restore point or rerun SFC and reboot afterwards like I'm supposed to and see if that actually fixes things. Which one would you suggest?

Glad to hear some progress is being made.

1. Yes, run SFC with a re-boot after each run, three times even if it says it's fixed the files.

2. No problem, ask any questions you have.

4. Best way to proceed and save some time.

Run SFC with re-boots first, hopefully that will repair the faulty files.
If that doesn't help then use an earlier restore point.

Let us know the progress.

I've uninstalled Norton.

Ran SFC 6 times with reboots after each. No improvement. Still says there are files that that it couldn't fix.

I also don't have a restore point any older then the one I already used.

It's looking like I might have to do a clean/repair install. While I know that a clean install is always better I think I'm going to have to go with a repair install. I don't have the time to reinstall all my programs and things.

Of course if you have other suggestions or ideas I'm open to them.

As I side note my computer has remained stable so far and I haven't had any problems recently. I also redid the memtest on the RAM individually, letting it go for 7 passes on each and they came up with no errors. So if it is RAM related it's gotta be the DIMM slots. Though I'm getting the sense that it might not be as related to that as it is to these corrupted windows files.

Just remember that a Repair Install can sometimes take up to 10 hours or more, depends on how many programs you have installed.
Let it run until it finishes, don't stop it unless you have saved any data in that partition and want to do a clean install.

You should make a DiscWizard image backup of that partition before you start, just in case.

It could be the corrupt Windows files causing the crashes.
If your RAM passes individual testing and fails with all four cards installed, it usually can be fixed by adjusting the settings.
We can look at that after the Windows files are fixed.

Let us know your progress.

Okay. I won't be able to do the clean install until tomorrow probably so I'll update then.

Out of curiosity next time I do a clean install how would you recommend I partition out my HDDs?

Right now I've got Windows and everything all on one big partition. I've got a 1TB drive I use as my main drive. My main concerns would be running games off of other partitions (since I mainly use my computer to game) but also personal files (music, pics, etc).

It is best to put all programs, including games, in the same partition as the OS.
All data, pictures, video, music, pretty much everything except the OS and programs, in a separate partition.
This will also make it easier to make your Image backups and restore the OS partition if needed, not risking your data partition.

It will depend on the size of all your programs.
I had no problem with my first 40GB SSD, with OS and all programs, my 120GB SSD is partition into two with Win7 and Win8, all data on the HDDs.
Unless you need to optimize your HDD space, I would make the OS/programs partition 60-80GB, even 100GB if you can spare the space.

Move all your personal data to another HDD, then make a DiscWizard Image of your C drive for safety.

You can post a snip of your Disk Management if you want advice on the best way to make the changes.
Have you used Free Partition Software - MiniTool Partition Wizard Home Edition 7.6
The Partition Wizard Bootable Flash Drive is the recommended method.
This program is very good and recommended by many members here.

Let me know if you have any questions.

Thanks for all the advice. I'll definitely keep it in mind when doing my next install of Windows.

I have not used that software before.

I did the Repair install and everything went perfectly smooth. Just finished doing all the updates.
