It only happens when I try to open certain website which requested some add-ons after I updated to Windows 8.1. The Windows restart automatically, with gentle remainder' For the error you could search onlune ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY' something like this. There are tons of troubles have been mode after a updated to Windows 8.1. And error message 'LogiLDA.dll missing. The specified module could not be found' shows every time when I turn on my computer. Can anybody help me to fix? Thanks.
