Persistent BSOD 0x19 BAD POOL HEADER ntkrpamp.exe

[fugue]

Hi-I am getting persistent BSODs 0x19 BAD POOL HEADER ntkrpamp.exe. Before the BSOD, my display freaks out, looking similar to a cracked/defective LCD with lots of noise, then restarts with a "boot error" message that moves on to a good boot after I hit "enter".

It is a Toshiba Satellite L300D notebook running Win7 Ultimate 32bit. Have tested the RAM w. Memtest-all is OK there. Recently replaced a buggered battery, and cloned the original HD to a bigger 500GB TravelStar. The BSODS predate this problem, tho'.

I have gone through the process of deleting and installing outdated drivers, but I'm not sure I have done a thorough job. Hoping that I don't have to do a clean install of Win7.

Thanks in advance for any help.

Well. Please carry out these steps:

Based on the bugchecks, I would recommend you follow and complete the steps given below:

1. If you are overclocking any hardware, please stop. Reset any changed values back to default and reset/clear CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS. Uninstall any overclocking tool as these can also be a reason of blue screens.

2. Uninstall your current antivirus software. It can be a cause of BSOD very often. Please remove it with its removal tool and use Microsoft Security Essentials in its place. Malwarebytes is a great combination with it. Go through this thread for more info.

3. Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors. Post back your logs for the checks after finding them using http://www.sevenforums.com/tutorials/96938-check-disk-chkdsk-read-event-viewer-log.html

4. Run http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html to check windows for integrity violations. Run it up to three times to fix all errors. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations.

5. Make scans with Kaspersky TDSskiller and ESET Online scanner.

6. Perform a Clean Start up, this will help avoid any problematic applications from bugging the system.

7. Use Revo Uninstaller Free to uninstall stubborn software. Opt for Advanced Mode and uninstall the software, delete the leftover registry entries.

8. Use Crystal Disk Info to upload a screenshot of your Hard Drives (s). Test your Hard Drives (s) running a Hard Drive Diag.

9. Test and Diagnose RAM issues with http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html. Pay close attention to Part 3 of the tutorial "If you have errors" Take the test for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.

10. Monitor hardware temperature for overheating issues with system monitoring software like Speccy or HWMonitor. Upload a screen shot of the Summary tab as well:

• Piriform - Speccy
• CPUID - HWMonitor
