hi im new here i keep on getting this blue screen like once every other month i've been tryin looking around to see what's causing it but no luck i have an attached minidump file with my post

BCCode: a
BCP1: 0000000000000000
BCP2: 0000000000000002
BCP3: 0000000000000000
BCP4: FFFFF80002E94734
OS Version: 6_1_7601

According to Carrona.org, STOP 0x0000000A: IRQL_NOT_LESS_OR_EQUAL
Usual causes: Kernel mode driver, System Service, BIOS, Windows, Virus scanner, Backup tool, compatibility.

And, here it is Norton.

Code:

fffff880`03fb24f8  fffff880`041769f0Unable to load image \??\C:\windows\system32\Drivers\SYMEVENT64x86.SYS, Win32 error 0n2
*** WARNING: Unable to verify timestamp for SYMEVENT64x86.SYS
*** ERROR: Module load completed but symbols could not be loaded for SYMEVENT64x86.SYS

And Again .... Norton!

Code:

*** WARNING: Unable to verify timestamp for BHDrvx64.sys
*** ERROR: Module load completed but symbols could not be loaded for BHDrvx64.sys
 BHDrvx64+0x1372e0

And yet again ... Norton!

Code:

fffff880`03fb2168  fffff880`02e02ab8Unable to load image \??\C:\Program Files (x86)\Common Files\Symantec Shared\EENGINE\EraserUtilRebootDrv.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for EraserUtilRebootDrv.sys
*** ERROR: Module load completed but symbols could not be loaded for EraserUtilRebootDrv.sys
 EraserUtilRebootDrv+0x2ab8

My suggestion is to uninstall Norton using Norton Removal Tool.

For security, use Microsoft Security Essentials - Free Antivirus for Windows, with windows inbuilt firewall and free MBAM as on demand scanner.

Let us know the results.
