Hey guys,

I got a problem..

I get random BsOD pop-ups and i don't know what to do.

Mostly i get 0x0000004E saying PFN_LIST_CORRUPT and 0x00000050 PAGE_FAULT_IN_NONPAGED_AREA.

PFN_LIST_CORRUPT pop-ups randomly, doesn't matter if im doing something or not but PAGE_FAULT.... pops-up only when i start a game (any game).

So i downloaded BlueScreenView program to help me. It says that both errors are caused by driver ntkrnlpa.exe

So if you know how to fix this pls reply as soon as possible




my spec:

OS: windows xp professional SP3

Processor: Intel® Core™2 Duo CPU E7500

Memory: 3584MB RAM

Display adapter: ASUS EAH4650 series

Motherboard: ASUS P5KPL-SE

Hello Name Here.... Welcome to
GeeksToGo,


I'm sorry to hear about your issue. We will try to help you resolve this as soon as possible.

• Please understand we are all volunteers and we are not here all the time.
• Sometimes it may be a extended amount of time to get back to you. If it has been
  more then 3 days please shoot me a PM and I will try to get back to you quickly
  then.
• Please do the following and supply the requested information as needed. If you
  don't understand my instructions please ask and I will try to explain them
  clearer for you.
• Do not attempt any steps unless instructed or ask before to
  make sure they will not cause any further issues.
• If you are receiving assistance in any other forum site please let us know as there may be conflicting advice given.

The most obvious reason for this is memory so we'll check that first.


A If you have more than one RAM module installed, try starting computer with one RAM stick at a time.

NOTE Keep in mind, the manual check listed above is always superior to the software check, listed below. DO NOT proceed with memtest, if you can go with option A

B. If you have only one RAM stick installed...
...run memtest...


1. Download - Pre-Compiled Bootable ISO (.zip). If you prefer to use the USB version then use this link USB KEY
2. Unzip downloaded /memtest86+-4.20.iso.zip file.
3. Inside, you'll find /memtest86+-4.20.iso file.
4. Download, and install ImgBurn: http://www.imgburn.com/
5. Insert blank CD into your CD drive.
6. Open ImgBurn, and click on Write image file to disc
7. Click on Browse for a file... icon:



8. Locate memtest86+-4.20.iso file, and click Open button.
9. Click on ImgBurn green arrow to start burning bootable memtest86 CD:



10. Once the CD is created, boot from it, and memtest will automatically start to run. You may have to change the boot sequence in your BIOS to make it work right.

To change Boot Sequence in your BIOS

Reboot the system and at the first post screen (where it is counting up memory) start tapping the DEL button
This will enter you into the Bios\Cmos area.
Find the Advanced area and click Enter
Look for Boot Sequence or Boot Options and highlight that click Enter
Now highlight the first drive and follow the directions on the bottom of the screen on how to modify it and change it to CDrom.
Change the second drive to the C or Main Drive
Once that is done then click F10 to Save and Exit
You will prompted to enter Y to verify Save and Exit. Click Y and the system will now reboot with the new settings.


The running program will look something like this depending on the size and number of ram modules installed:




It's recommended to run 5-6 passes. Each pass contains very same 8 tests.

This will show the progress of the test. It can take a while. Be patient, or leave it running overnight.



The following image is the test results area:



The most important item here is the “errors” line. If you see ANY errors, even one, most likely, you have bad RAM.

If the above shows memory is good then please do the following.




Go to

Start and then to Run
Type in Chkdsk /r Note the space between k and /
Click Enter ...It will probably ask if you want to do this on the next reboot...click Y
If the window doesn't shutdown on its own then reboot the system manually. On reboot the system will start the chkdsk operation
This one will take longer then chkdsk /f

Note... there are 5 stages...
It may appear to hang at a certain percent for a hour or more or even back up and go over the same area...this is normal...
DO NOT SHUT YOUR COMPUTER DOWN WHILE CHKDSK IS RUNNING OR YOU CAN HAVE SEVERE PROBLEMS
This can take several hours to complete.
When completed it will boot the system back into windows.

Reboot after your done running chkdsk /r...
then Go to Start...Run and type: eventvwr.msc press Enter
When Event Viewer opens, click on Applications... then scroll down to Winlogon and double-click on it. This is the log created after running Checkdisk...copy and paste the log back here


We will advise after studying the log.








Run hard drive diagnostics: http://www.tacktech....ay.cfm?ttid=287
Make sure, you select tool, which is appropriate for the brand of your hard drive.
Depending on the program, it'll create bootable floppy, or bootable CD.
If downloaded file is of .iso type, use ImgBurn: http://www.imgburn.com/ to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.

NOTE. If your hard drive is made by Toshiba, try the Hitachi DFT CD Image version of the software

Thanks to Broni for the instructions

Hi,

So i checked the RAM sticks manually, both work, I haven't seen 0x0000004E in a while but im getting 0x00000050 everytime I try to open a game.

I downloaded memtest and burn'd it on a cd, rebooted my pc with it. it took 8 hours to finish and it found 1302272 errors

This means I have to buy 2 new RAM sticks?

Not yet. Now you need to test each module by itself using memtest86.
Also just a FYI memtest could be seeing a issue with the CPU so this may be something other then the memory.
