Hi,
My computer is crashing once a day and due to same error code.
Typical error log looks like:
Problem signature
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033
Extra information about the problem
BCCode: a
BCP1: 0000000000000000
BCP2: 0000000000000002
BCP3: 0000000000000000
BCP4: FFFFF80002A817B6
OS Version: 6_1_7600
Service Pack: 0_0
Product: 256_1
I have windows 7 ultimate 64 bit.
When I viewed the crash dumps I see that fault is due to ntoskrnl.exe every time.
Could you please tell me what may be the reason for same.
I am attaching my dumps for reference.
Thanks for your help.
Sachin
This crash was probably caused by vfilter.sys which is part of your VPN client software. I would remove it to test. BTW for future reference could you zip all the DMP files into one zip file?
Thanks
Ken

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 0000000000000000, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff80002a8d0b6, address which referenced memory
