My Windows 8.1 Pro desktop BSOD with PAGE_FAULT_IN_NONPAGED_AREA, in Norton security routine symevent64x86.sys. Error description is (SYMEVENT64x86!EventObjectDestroy+0x5A1)
Bugcheck code: 0x50 (0xFFFFE000F2F016B8, 0x0, 0xFFFFF8006B4B3B43, 0x2). Bug analysis was performed with WhoCrashed, which suggests that this is most likely a hardware issue. This assessment is reasonable since systems testing, including Memtest86 (64-bit), were error free.The BSOD occurred while I was creating an email message in Outlook 2007.
