I just bought an acer aspire v5 with an intel i5 processor.
After backing up my files I had no problem but when I started to download new files I get these messages within 30 minutes of turning on my laptop.

I have attached the message that comes up.

Please help as I have no clue what to do.

P.s. I have heard in order to solve this problem I need to post all the details of my PC... but I dont know how to do that either lol

I appreciate your help!:)

Hi, having a similar problem to OP, and some other posters. Whenever I run utorrent, the computer restarts itself soon after. Tried a few things, including turning off IvP6 and completely getting rid off Mcafee (already had done it but got rid of the remaining traces in the system) but no luck. Running a Dell Inspiron, recent ugrade to windows 8.1.

Did my best to follow the tutorial for BSOD posts and got the zip fie here.

Hope you can help, would really appreciate it.

Thankss :D

Hi abnf584

Please try the below steps one by one.

1. Remove McAfee remnants.

McAfee drivers are still present in the last crash dump.

ffffd000`3787b198  fffff800`00e1112aUnable to load image \SystemRoot\system32\drivers\mfewfpk.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for mfewfpk.sys
*** ERROR: Module load completed but symbols could not be loaded for [COLOR=#ff0000][B]mfewfpk.sys[/B][/COLOR]

First uninstall it from Control Panel --> Programs and reboot the machine. To remove it fully, please download and run MCPR from the below link.


2. If the issue continues, disable Teredo Tunneling Adapter service as a test.

First open an elevated command prompt as per http://www.eightforums.com/tutorials/2754-elevated-command-prompt-open-windows-8-a.html

Then enter the below command exactly and reboot the machine.

netsh interface teredo set state disabled

Let me know our findings with next reply.

When the computer starts he asks to send a report to windows support, in that report he sends the files:
