BOSD 0x4E PFN_LIST_CORRUPT (mainly while booting)

Hello (again) Guys,

recently my PC started to give me the above mentioned BSOD 0x4E. It mainly happens while booting ~during the part where the lightballs start to form the Windows 7 Logo. One time it happend shortly after I got into Windows and today for the first time after the PC was running for a while.

I'll run Memtest84+ tonight and see if I get errors. Already did chkdsk and sfc with no errors.

Basic System Infos:

OS: Windows 7 Prof x64 retail (University Licence)
Age: System was bought around January/February so Hardware and OS are from that time.

Motherbord: ASUS P7P55D Rev 1
CPU: Intel Core i5 760
RAM: G.Skill F3-12800CL9-2GBNQ 4gig
GPU: Nvidia GeForce GTX 460
HDD: 500gig Samsung HD501LJ (the only old component in the system its ~4y old)

These were caused by a memory exception. Please run these two tests to verify your memory and find which driver is causing the problem.


1-Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 6 or7 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

2-Driver verifier

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Thanks for the fast reply. I'll run Memtest when I go to sleep and see if I get Errors and will do the verifier thing tomorrow. I will post the results tomorrow evening because the diffrent timezones *sigh*

Oh and also is it needed to run Memtest from CD? I got the USB Version because I have no CDs here atm... is there a diffrence?

Hello zigzag3143,

I let Memtest run through the night. 10h+, 14 Passes and no Errors. I tested it with my normal Setup (2 Sticks, Slot 1 and 3)... should I test again with a single Stick?

Oh and I will start to look into the Driver Verifier now. Will report if something happens.

Edit: Oh and I forgott to say that in the Report it says I have no anti virus software but I have a University Licence of Sophos Antivirus running that is up to date. Also another thing that I noticed, some of the BSODs didnt create minidumps? or they got deleted. I had BSODs with rdyboost.sys as cause. I unpluged some of my USB devices (Headset, Printer) and now only my mouse and 2 HDDs are present (the HDDs are switched off during the booting routine).

Ok used the Driver Verifier. The moment I tried to restart after the Verifier was active I got a BSOD during the Windows Logo. Had to use the Repair Disc to restor the System to be able to post.

I'll add the new dumpfile. Looks like it was caused by Daemon Tools...

After the recovery the system ran for a while then I got the old 0x4E again. Didnt uninstall Deamon Tools yet. Will do that right now.

Here the Minidump of the recent crash.

Edit: uninstalled Deamon Tools.

This was Related to dtsoftbus01.sys Virtual Bus Driver from DT Soft Ltd. I would remove it at least to test.

Hey zigzag3143,

I already removed Deamon Tools yesterday night. Searched for the File you linked, no trace of it on the PC. Should I run the Driver Verifier again?

Just started the Driver Verifer again after uninstalling Deamon Tools. First time after restart I got into Windows but it crashed short after. 2nd restart crashed during Windows Logo. 3rd restart got into Windows but crashed after a few mins.

Will post the Minidumps.

And the next crash. Looks like it was caused by MagicISO. I was looking for an alternative programm to use for Deamon Tools. MagicISO was recommended here in the forum by another MVP. Looks like it didnt work for me...

Edit: I uninstalled MagicISO just to be sure...

Disabled the Driver Verifier for now. I cant even post here without the PC crashing to BSODs. Here the last 2 (the last happend while restarting after disabling the Driver Verifier).

Also sorry if I posted some of the Minidumps multiple times... I kinda lost the overview over which I already posted and which I didnt post yet :/

Let chkdsk /r run and had a new crash after the test was finished. I kinda lost track of all the dumpfiles... I'll just post all the dumps from today it seems like the BSOD after the chkdsk overwrote an old dumpfile?<_<

Please run memtest

Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots

I already did the Memtest with both Ram Sticks in (Slot 1/3) for 14 passes without any Errors. I now removed one Stick and will rerun Memtest for each slot / stick. Will report again if something happens.

Just finished the first Test: Stick 1 in Slot 1 - 6 Passes 0 Errors

Ok I did what you told me and tested every Stick in every Slot. I'm not completely finished yet but I will run the last test when I go to sleep later. So far I have the following results.

Both Sticks together: Slot A1 and B1 - 14 Passes no Errors
Slot A2 and B2 - System does not boot

Stick 1 alone: Slot A1 - 6 Passes no Errors
Slot A2 - System does not boot
Slot B1 - 3 Passes 1 Error (I stoped the Memtest there)
Slot B2 - System does not boot

Stick 2 alone: Slot A1 - 6 Passes no Errors
Slot A2 - System does not boot
Slot B1 - 6 Passes no Errors
Slot B2 - System does not boot

I'll also post the dumpfiles that I got during the RAM changing. The Bad Pool Header and Memory Management BSODs were caused by dust on the Sticks/Slot, after I cleaned the Slots/Sticks they stoped immediately. One of the PFN BSODs happend while I was trying to boot with Stick 1 in Slot A1 and the other PFN BSODs happend with both Sticks in Slot A1/B1 (all the crashes that happend short after I got into Windows).

Edit: Regarding the "System does not boot" thing. In the manual Slot A2/B2 are only used if you run a full 4 Stick Setup. For singlechannel it says use either slot A1 or B1, in both I was able to boot. And for Dualchannel it says use Slot A1+B1 and it worked just fine. So I guess the A2/B2 Slots arent ment to work without a full setup.

Ok is just finished the last Test.

Stick 2 in Slot B1. 6 Passes no Errors.

So the only Error I got was with Stick 1 in Slot B1... but that Stick had no Error in Slot A1. -_-
I dont understand this pattern... if the Slot B1 was damaged then the 2nd Stick should also produce Errors and if the 1st Stick was damaged then it should produce Errors in Slot A1... is it possible that the Error in Memtest was a fluke? Or should I test the 1st Stick again to be sure that its ok?

Edit: Is it possible that the Slot/Stick got dirty during the changing process and that caused the Error?

I also have another BSOD from earlier Today (befor I did the last Test I used the PC with both Sticks in Slot A1/B1).

Also I'm wondering because the last time I had RAM issues I had many diffrent BSODs now I only get the same 0x4E BSOD again and again.

This one was Related to rdyboost.sys ReadyBoost Drive from Microsoft Corporation. I would disable it.
