Windows 7: BOSD 0x4E PFN_LIST_CORTUPT (mainly while booting)

New crash.

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


RAM - Test with Memtest86+

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.

New crash while booting today happened 3 times before I was able to get to Windows.

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