Pfn_list_corrupt bsod

kadrek · 31 Dec 2013

I've had this desktop and have gone long periods of time with no bsods and then get them constantly for a while. I have never been able to get windows to create minidumps for the life of me, until I just upgraded the video card. I changed out and old 9800gt for a R9 270x today and am still getting bsods. I'm typing this on my laptop, desktop just got another bsod, IRQL_NOT_LESS_OR_EQUAL while typing this. It also crashed and said attempted to write to readonly memory today. I checked the minidump folder with little hope but there were finally some in there! I don't know what caused it to start creating them as I changed the card today, the 30th, but it started creating them on the 24th. I have ran memtest and returned ram because it got errors. I then got new ram and it still have errors, I think there may be a bad ram slot.

I don't know if my system specs show so here they are:
AMD Phenom II x4 965 BE
G. Skil 4GBx2 1600
ASUS R9 270x
Gigabyte GA-770T-USBB3
Intel 120GB SSD
500GB WD Blue

Hello :) .

The bugchecks are all over the place so i would first like to verify that the RAM modules / slots are
in a well and working order then scan for malicious software then we will go from there to
deal with some outdated and re appearing drivers, some being the Ethernet and Audio.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

First run it with all the existing/installed RAM modules. If it comes with no error, all is good.

But if it starts showing errors, Stop testing. Errors/red lines means one or more RAM is faulty. But the fault may occur due to a faulty DIMM slot, too, which is a motherboard component. Using memtest86+, you can discriminate between a faulty RAM and a faulty motherboard.

How? Say you have two RAM sticks and two DIMM slots. You obtained errors at the test with all RAM sticks installed. Now, remove all the sticks but one. Test it in all the available slots, one by one. Continue the same procedure for all the available sticks.
How to make the inference that is it a RAM issue or it is a motherboard issue? Suppose you have got the result like that:
No code has to be inserted here. It is a RAM, a bad RAM.

But if you have got a result like that:
No code has to be inserted here. It is a motherboard issue. The particular slot is bad.

Please scan for possible infection and file corruption.

Download TDSS-Killer and scan for rootkits.
Download Kaspersky Rescue CD and scan for other types of infections. (a how-to tutorial)
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.
