BSOD 3 times PFN_LIST_CORRUPT, BAD_POOL_HEADER, Unknown

[dcook22]

Hi all,

In the past few days I have had 5 BSOD's. Two occured overnight and I only knew they occurred because in the morning I saw that windows had recovered from a serious error. Three, however, happened last night. The first was a PFN_LIST_CORRUPT error. The second was BAD_POOL_HEADER. The third kind of rebooted without my being able to see any cause, but the error code was x and all zeroes with a 1 at the end. Sorry, don't know how many zeroes there were.

I am posting this on the PC that crashed. It is functional, but evidently somewhat unstable.

History: Yesterday I was on my PC, literally, for hours. I was using Windows Media Player quite a bit to view saved videos. I was on Yuotube, and surfing the net. I spent much of the day transferring almost 200 GB of saved videos to an external HDD. So my rig was multitasking rather well.

Then I had the first BSOD with the PFN_LIST_CORRUPT error. the system rebooted and when it was up, I immediately went to the internets to find out what a PFN_LIST_CORRUPT error was. I got through half a webpage when it BSOD'd again. This time with the BAD_POOL_HEADER error. I researched this a bit and it referenced possible driver issues.

I have always been from the school of "if you video card is working, leave the drivers alone". I checked Windows Update and there are only 29 optional updates. No important ones. One of those options is a new Nvidia driver. I can DL and install that if it might help.

While researching the BAD_POOL_HEADER error I decided to try multitasking again to see if I could recreate the error. I started watching a .mov file and after about 10 minutes I got a new BSOD, but this time with no error that was clear to me.

I ran chkdsk c: /f/r overnight. This morning my system was up and running when i got up.

That's where I am at.

Can you guys please try to help me discern why I am having these issues?

Current chages: I have made no hardware changes to my system lately. In the past 5 days, I would say the only software changes i have made have been deleting ans stalling Minecraft mods because my kids likes to watch me play minecraft. Yesterday I installed adblock and adblock pro into Google Chrome, but I was not running chrome when these BSOD's occurred. IE9 is my default browser.

By the way: I do not have an extra PSU, mobo, or CPU to run tests with. I do have 4 RAM sticks so, if necessary, I can rum memory tests with different sticks.

Any and all help is appreciated. Thanks in advance.

Hello dcook22 , welcome aboard.

All your bsod dumps indicates to two things ... ntoskrnl.exe and Ntfs.sys .



I would suggest you to

• run http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html
• run http://www.sevenforums.com/tutorials/433-disk-check.html
• revert back from any overclocking if there
• run http://www.sevenforums.com/tutorials/715-memory-diagnostics-tool.html .

Thanks for the reply, Arc. I'll do those things and reply. Should I be looking for dump files or anything?

Also, I have the win 7 DVD to reinstall/repair windows if necessary, although I'd like to be able to do that without having to reinstall all my programs if possible. Let me know if that helps.

Hi Arc,

Sorry for the long delay. I work a lot of hours and finally completed the tests you recommended. I ran all three tests (I don't overclock so there was nothing to revert) and all three found no errors. I had run chkdsk /f /r the day before I posted (soon after the BSOD's) and I think it found a couple of things to fix at that time, but nothing too bad. This time, though, all tests were clean.

I did install new nvidia drivers since the last time I got a BSOD and haven't gotten one since.

I'm not sure what to say about the ntoskrnl.exe and the ntfs.sys. As mentioned, I do have the Win 7 DVD if you think I should copy over some files.

Any thoughts?

Thanks again for your help.
