Windows 7: Random BSODs

20 Dec 2012   #1

Windows 7 64-bit Enterprise
Random BSODs


I have had an issue with my HP laptop for a few months now. It crashes at least twice a day when I'm using it, often having separate causes. It will crash while playing a game, i.e. Skyrim, Borderlands 2 or Minecraft; while recording with FRAPS, while surfing the internet with Safari and/or Internet Explorer, or simply while sitting idle with no open programs.

I have been attempting to diagnose the issue, Memtest was ran for 6 passes, after which zero errors were found. SFC/scannow command was ran in CMD and found no errors, Chkdsk was also run and found zero errors.

I have been in contact with HP about the issue, and their solution was to have me send in the laptop and they would diagnose it. They just replaced the ram, reloaded the OS and sent it back. It crashed the first day I got it back, shortly after taking it out of the box, as well as intermittently thereafter.

I also have updated all drivers, and tried other versions of drivers as well.

I am attaching the SF Diagnostic Tool Zipped Folder as well.

-Thank you for your help in advance.

Welcome to SevenForums.

* How old is the laptop?
* Have you checked for any accumulated dust?
* Overheating issues?
* Any BSOD-s in safe mode?

Your video card drivers are out of date.

Norton is known to cause BSOD, consider uninstalling it with the Norton Removal Tool and replace with Microsoft Security Essentials at least to test.Microsoft Security Essentials.
Recommended from a strict BSOD perspective, compatibility & stability compared to other antiviruses/internet security software. It is free and lightweight:-
Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Run a full scan with both (separately) once downloaded, installed and updated.

Hard drive

Upload a screenshot of your hard disk using CrystalDiskInfo:Make a hard drive test from the hard drive manufacturers website:

Reduce items at start-up. Nothing except anti-virus is required:

Perform a System File Check:
  • Click on the start
  • Type CMD on Search
  • Left click and Run as Administrator
  • Type SFC /scannow
Full tutorial here:

If the above does not bring stability run memtest:

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.
The goal is to test all the RAM sticks and all the motherboard slots.

Check your motherboard manual to ensure the RAM sticks are in the recommended motherboard slots. Some motherboards have very specific slots required for the number of RAM sticks installed.

If you get errors, stop the test and continue with the next step.

1. Remove all but one stick of RAM from your computer (this will be RAM stick #1), and run Memtest86 again, for 7 passes.
*Be sure to note the RAM stick, use a piece of tape with a number, and note the motherboard slot.
If this stick passes the test then go to step #3.

2. If RAM stick #1 has errors, repeat the test with RAM stick #2 in the same motherboard slot.
*If RAM stick #2 passes, this indicates that RAM stick #1 may be bad. If you want to be absolutely sure, re-test RAM stick #1 in another known good slot.
*If RAM stick #2 has errors, this indicates another possible bad RAM stick, a possible motherboard slot failure or inadequate settings.
3. Test the next stick of RAM (stick #2) in the next motherboard slot.
*If this RAM stick has errors repeat step #2 using a known good stick if possible, or another stick.
*If this RAM stick has no errors and both sticks failed in slot#1, test RAM stick #1 in this slot.
4. If you find a stick that passes the test, test it in all the other motherboard slots.

If Part 2 testing shows errors, and all tests in Part 3 show errors, you will need to test the RAM sticks in another computer and/or test other RAM in your computer to identify the problem.

In this way, you can identify whether it is a bad stick of RAM, a bad motherboard, or incompatibility between the sticks.

Errors are sometimes found after 8 passes.

Do this test overnight, before going to bed.

Sorry for the delay

The Laptop is new. I actually just got finished with another round with HP in which they simply decided the best course of action is to replace the laptop. However, the BSOD's are still occuring. I have tried updating all drivers that I can, and even uninstalling one completely, and using the generic Microsoft driver.

No accumulated dust, and temperatures never go above 75* C (for the GT 650m) and 80* C for the i7-3610qm

Norton has been removed, and MSE has been installed. A majority of my BSOD's are ntoskrnl.exe, fltmgr.sys, and ntfs.sys

Those are the frequent ones that I was also experiencing with my previous laptop.

SFC/scannow was also run, no integrity violations. Memtest ran for 8 passes, no errors found.

I am at a loss as to what is causing the crashes.

Is it possible the OEM operating system from HP is buggy?

Do you mean you're getting BSOD-s on a new laptop?
Please upload the latest dump files.

Have you reinstalled windows? Does it still crash?

NTFS.sys and fltmgr.sys sound like a hard drive problem. Does the laptop have a SSD or a HDD?

You may want to start with a Clean Reinstall - Factory OEM Windows 7. Do not install the factory bloatware that comes with the system. Go through this link: Clean Up Factory Bloatware for that.

Let us know the results.

I have not reinstalled windows on this laptop. Previously I did do a factory re-install. I will do the steps provided and get back with you.

Before I jump into formatting and reinstalling the OS, is it possible that an external HDD may be the cause of my BSOD's?
I use a 1TB Seagate USB 3.0 HDD
I am attaching a new .zip with the SF Diagnostic Tool results.

Edit: The BSOD's don't always occur when the HDD is connected. But, it is/was (as far as I know) connected within the same boot. Would formatting the External HDD help be worth trying even though Chkdsk /f and /g showed no errors?

Crashes are all over the place. I would do a clean install.
Anyway, can you upload screenshot using crystal disk linked on my first reply?
BTW, do you get BSOD-s in safe mode?
Edit, I saw them.

They look OK.

I have not experienced a BSOD in safe mode. I'm not often in safe mode for too long though (a few hours one day).

How many hours?

Can you stay in safe mode for 12 hours and report if you got blue screens? :)
