BSoD Locale ID 3081 BC Code c8

Opopanax_78 asked on

Hi guys,

I'm not overly savvy when it comes to PCs and have been scouring the net for help on how to solve a BSoD issue.

OS:

Intel Core 2 Quad CPU Q6600 @ 2.40GHz  2.40GHz

4GB RAM

Vista 32 bit Service pack 2

GPU:

ASUS GeForce GTX560Ti

BSoD occurred on load up after logging into Windows and waiting for general starup of applications to occur; so approx 2 mins after my desktop had opened. Since this time, i ahve restarted PC numerous times and more often than not, it will get to same point before BSoD displays. I have unplugged my seagate external, my headphones and restarted after both. Sometimes I can enter safe mode and sometimes not. i.e. my keyboard works at that point intermittently. The details of BSoD are as follows:

Locale ID: 3081

BCCode: C8

BCP1: 00000000

BCP2: 00000002

BCP3: 00000000

BCP4: 00000000

O.S Version: 6_0_6002

Service Pack: 2_0

Product: 768_1

OS version: 6.0.6002.2.2.0.768.3

The only software i can think that has been updated recently is as follows:

Avast

Nvidia

Windows updates

Plain English would really be appreicated here as I truly am a layman when it comes to computer stuff. Thanks in advance.

Thanks for the dumps!

All of the attached DMP files are of the IRQL_UNEXPECTED_VALUE (C8) bug check.

This indicates that the processor's IRQL is not what it should be at this time.

This error is usually caused by a device driver or another lower-level program that changed the IRQL for some period and did not restore the original IRQL at the end of that period. For example, the routine may have acquired a spin lock and failed to release it.

If we take a look at the call stack:

^^ aswNdis2/aswTdi are avast! drivers, and seem to be the driver causing the improper IRQL.

IRQL << 16 <--- IRQL at the time of the crash.

IRQL << 8 <--- This was the expected IRQL (what it should have lowered to).

Remove and replace avast! with Microsoft Security Essentials for temporary troubleshooting purposes as it appears to be causing conflicts:
