  1. Hi newcomer here,

    Just recently I've encountered random reboots/BSODs (2-3 times a day)happening to my computer. When I checked Event Viewer the error comes up as The computer has rebooted from a bugcheck. The bugcheck was: 0x0000004e (0x0000000000000002, 0x0000000000182784, 0x00000000001bffff, 0x0000000000000001). I've been going up the wall looking for a solution. Here's a couple of mini-dumps any help or solution from reading these are very welcome and appreciated. Thank you.

    Of the two dumps the most significant error is 0x4E PFN_LIST_CORRUPT because it is probably the strongest error code indicating corrupted memory and that is what it specifically cited as your issue.

    You need to run Memtest on your RAM. It is free and safe.

    See the link below and 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; 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.


    * Get back to us with the results.

    *** If Memtest shows no errors then find the voltage specs of your RAM and compare it to the voltage setting in your BIOS. Do they match?
