I actually have no clue why this problem is caused and I've already done following thing;
Try to update software (they are already latest ones)
Try different codec's
Try different account with Admin access
Install and replace flash player
Note: While running youtube vid's, flash plugin's seems to be crashing too and they are already updated.
Browser tries, Mozilla Firefox/Chrome/IE
Any and all help on this will be appreciated and I'm sorry if this was repetition of someones same issue, but I couldn't find one when I searched

Already done that. I even tried with separate shark codec pack for win7x64 (without having K-lite on). I even tried running VLC alone and uninstalled all codec pack's. Problem still persists.
