Hello There, This is my first post however I have been having no luck with solving my BSOD crashes myself. I have been experiencing the issues for a number of months, however they seem to be becoming more regular. The crashes occur generally during video playback either from harddisk or from a network Samba server. Sometimes the crashes occur, sometimes not. They do not seem to be affected by codecs or resolutions as sometimes a 1080p movie will play flawlessly and a SD video may cause crashes. Crashes also seem to be triggered from YouTube videos, generally higher resolutions (1080p). I am unable to reliably recreate the crashes due to the random nature of them. Below are the BSOD details that I have managed to document(newest to oldest):MEMORY_MANAGEMENTIRQL_NOT_LESS_OR_EQUALSYSTEM_SERVICE_EXCEPTION(No name given, Stop Code: 0x000000240, Ntfs.sys named) Other Issues (probably unrelated?)Unable to open removable drives with double click (....not found) (Was fixed temporarily with registry fix however returned)Unable to copy and paste from Chrome into WordGeneral system slowness, especially in boot. Full virus scans run and no issues. I believe it may be an issue with the Graphics card or memory, however it is strange that it is never triggered by video gaming even at high resolutions.

Any help much appreciated! Many thanks, Morgan314 03/03/13 17:25 Edit Some additional information I forgot to add, generally for the video playback I am using VLC Media Player as it plays the widest range of files, also when the system crashes a loud buzz is emitted from the speakers as if there is too much voltage on the speaker ports, just a lound buzz that changes with the volume.
