BSOD - Random timing / situations 0x50

As the title states, random BSOD. Started a few weeks ago.

"On Mon 10/29/2012 3:28:36 AM GMT your computer crashed
crash dump file: C:\Windows\Minidump\102812-28563-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x7EFC0)
Bugcheck code: 0x50 (0xFFFFF30012816930, 0x1, 0xFFFFF8000317818D, 0x7)
Error: PAGE_FAULT_IN_NONPAGED_AREA
file path: C:\Windows\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This indicates that invalid system memory has been referenced.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time."

Welcome

Problematic software:

Code:

Start Menu\Programs\AVG	Public:Start Menu\Programs\AVG	Public

AVG contributes in BSODs. Please uninstall it with the Removal Tool and replace with free MSE at least to test.

Recommended antivirus program for Windows 7 based on stability compared to others:-

• Microsoft Security Essentials - Free Antivirus for Windows
• Malwarebytes - The Free version
• Good and Free system security combination.

Run a full scan with both (separately) once downloaded, installed and updated.

STOP 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA
Usual causes: Defective hardware (particularly memory - but not just RAM),
Faulty system service, Antivirus, Device driver, NTFS corruption, BIOS

After removing AVG, test your memory.

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.

• RAM - Test with Memtest86+
• Guide to using Memtest86+ - Geeks to Go Forums

The goal is to test all the RAM sticks and all the motherboard slots.

Check your motherboard manual to ensure the RAM sticks are in the recommended motherboard slots. Some motherboards have very specific slots required for the number of RAM sticks installed.

If you get errors, stop the test and continue with the next step.

1. Remove all but one stick of RAM from your computer (this will be RAM stick #1), and run Memtest86 again, for 7 passes.
Be sure to note the RAM stick, use a piece of tape with a number, and note the motherboard slot.
If this stick passes the test then go to step #3.

2. If RAM stick #1 has errors, repeat the test with RAM stick #2 in the same motherboard slot.
If RAM stick #2 passes, this indicates that RAM stick #1 may be bad. If you want to be absolutely sure, re-test RAM stick #1 in another known good slot.
If RAM stick #2 has errors, this indicates another possible bad RAM stick, a possible motherboard slot failure or inadequate settings.
3. Test the next stick of RAM (stick #2) in the next motherboard slot.
If this RAM stick has errors repeat step #2 using a known good stick if possible, or another stick.
If this RAM stick has no errors and both sticks failed in slot#1, test RAM stick #1 in this slot.
4. If you find a stick that passes the test, test it in all the other motherboard slots.

If Part 2 testing shows errors, and all tests in Part 3 show errors, you will need to test the RAM sticks in another computer and/or test other RAM in your computer to identify the problem.

In this way, you can identify whether it is a bad stick of RAM, a bad motherboard, or incompatibility between the sticks.

Look for an update on your BIOS version:

Update your graphic card drivers to their latest.

First uninstall from control panel, Click on the Start ► Control Panel ► Programs ► Uninstall a program ► Uninstall everything related to ATI. Delete remnants of its older driver using Driver Sweeper. Then get the latest drivers from the manufacturers website or from a reliable source like Filehippo.com

Run Disk Check on your hard disk for file system errors and bad sectors on it:

• Disk Check

Let us know the results

Good luck :)

Okay, update the thread when you're able to run memtest.

Thanks for the update, I hope everything is OK at your end.

Have you encountered any blue screens since making the other changes on your computer?

My system seems more stable and is booting up much more quickly now.

I really wish I had a USB stick, nothing to do today but sit at home and watch movies.

It's okay. Relax and watch movies. Get back to the thread if/when the computer blue screens or if there's anything you want to let us know.. :)
