The single most important error code received is 0x4E: PFN_LIST_CORRUPT because it is the strongest indicator of corrupted memory (bad RAM). And in your case corrupted memory was specifically cited as the cause of your system crashes.
Therefore you’ll need to run Memtest on your RAM.
1. Go to
www.memtest.org and download the latest ISO version which is 4.20. It is free and perfectly safe.
2. Burn ISO to a CD.
3. Place CD in your drive and reboot with CD in drive. (You might have to place your drive as first bootable in your BIOS) The test will take over.
There is a Tutorial:
How to use Memtest in our Guides and Tutorials forum; follow the instructions. There is a newer version than what is listed; use the newer. If you need to see what the Memtest screen looks like go to reply #21. The third screen is the Memtest screen.
Step1 - Let it run for a
LONG time. The rule is a
minimum of 7 Passes (not hours; this test is not measured by hours);
the more Passes after 7 so much the better. The only exception is if you start getting errors before 7 Passes then you can skip to Step 2.
There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.
If you have errors you have corrupted memory and it needs to be replaced.
Step 2 – Because of errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.
