Windows 7: BSOD ntoskrnl.exe +e6d50

17 Feb 2014   #1

Windows 7 Home Premium SP1 x64
BSOD ntoskrnl.exe +e6d50


I have been getting BSOD for the past 1-2 months. I noticed that it happens when I have a browser open. Not sure if that was the case every time.

When it started it happened a few times for a few days. I was using Avast and Mozilla Firefox. After few days like that I changed to Chrome, MSE and Malwarebytes Anti-Malware. It still hapens, but not as often. I got 2 BSOD if I recall correctly this week, one of which, last night while playing Hearthstone and watching Youtube stream.

Thank You in advance!

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

Errors are sometimes found after 8 passes.

Tip   Tip
Do this test overnight, before going to bed.

Are you sure about this? I don't think I will be able to manage that. It did not have such problem before? Can it just break down in that way just like that for no reason?

If you cannot manage even a memtest, better you don't opt for a troubleshoot.

And, if you ask for whether it is sure or not, remote assistance is not for you. We work based on the supplied data, not having the machine in hand.
