Windows 7: BSOD help (bad pool header & irql less or not equal)

02 Jan 2014   #21

Windows 7 Ultimate 64 bit


Actually, couple of seconds after I've installed all four modules tougher I got two crashs of bad pool header. I got it back to the store, where they changed them for new ones.

As i was typing this message, got another crash " An attempt was made to write to read-only memory"
(I was going to write how optimistic I am now).

Hmm that is almost too coincidental.
I want to scan for possible infections and running Driver Verifier.

Please scan for possible infection and file corruption, perform the scans in the order they appear in.
  • Download TDSS-Killer and scan for rootkits. Please upload the TDSSKILLER log which will be located in the C:\ partition once you boot back in normal mode.
  • Download AdwCleaner, it might ask you to download an updated version, do so. launch the program and click the Scan button, once it's finished go through the Folders tab and Files tab and see if it has detected any personally important files that you want to keep for now will deal with those later. Please upload the log file which will be created after removal procedure in a folder C:\AdwCleaner, if you are unable to find the log file simply launch AdwCleaner again and click the Report button.
  • Download Malwarebytes and DON'T activate the trail (uncheck the box at the end of the installation)
  • Follow this tutorial on how to use the SFC/ SCANNOW tool in Windows. See OPTION THREE in-order to upload the CBS log file.

It will make the system bit of slow, laggy.

warning   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Tip   Tip

Please enable driver verifier following this TUTORIAL | But using these settings:

  1. Go to Start and type in "verifier" (without the quotes) and press Enter
  2. Select "Create custom settings (for code developers)" and click "Next"
  3. Select "Select individual settings from a full list" and click "Next"
  4. Select everything EXCEPT FOR "Low Resource Simulation", "Force Pending I/O Requests", "IRP Logging" and click "Next"
  5. Select "Select driver names from a list" and click "Next"
  6. Then select all drivers NOT provided by Microsoft, Unknown, or Macrovision and click "Next"
  7. Select "Finish" on the next page.

I have returned the PC back to the store, they are replacing the motherboard, which is the next suspect.

Haven't tried any of the scans you recommended yet, hopfully i wont need to.

its been two days without crashes after they have replaced the motherboard.

But i have noticed something that i am not quite sure of. I bought 4 G.Skill modules which are 1600Mhz, but speccy says differently, is that normal?

Good news :)!
And yes that is normal, DDR or Double Data Rate will show up as half of the actual speed,
so 800*2 =1600.
