BSoD every other day

fullrich said:

Hi everyone,

in the last few weeks I've gotten BSoDs every now and then. It's pretty rare, usually less than once per day, but I'd still like to know what's the problem.

The BSoDs all occurred while I was listening to music (stored on a separate HD that has a few years on its back) and running torrents (not a hundred percent sure on this), so I'd suspect one of the involved HDs or the software (µTorrent/foobar2000), but I don't know how to prove this, so help would be greatly appreciated. My minidump files are attached. If you need more information, I'd be happy to provide it.

Thank you!

These were all caused by vfilter.sys which is part of your VPN client. I would re-install it with a fresh copy

Let us know if you need help

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: fffff80002e837b6, address which referenced memory

Phew, I expected worse. Thank you!

By the way, I used the Shrew Soft VPN client - maybe this is helpful for other people with similar problems. I'll just uninstall it, I don't need it anyways.
