Windows 7: Random BSOD, error 0x000000c5

Windows 7 Ultimate x64
Random BSOD, error 0x000000c5

Good day All,

Hope you are well,

I tried to find the problem with this BSOD myself but with no luck,

I would greatly appreciate your assistance in the matter.

The BSOD is completely random (from what i can tell) sometimes it happens once a week (I use the PC daily) and on bad days i can have a few of them in a day. They happen when the PC is idle, gaming, streaming or any other random activity hence my difficulty of actually figuring out what is causing it.

This is the event details that windows give me:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.
Locale ID: 1033

Additional information about the problem:
BCCode: c5
BCP1: 0000000000000008
BCP2: 0000000000000002
BCP3: 0000000000000000
BCP4: FFFFF8000220DB05
OS Version: 6_1_7601
Service Pack: 1_0
Product: 256_1

and attached is the DM LOG COLLECTOR .zip file as requested.

Thank you so much for your assistance in the matter,

You are getting Pool Corruption, the driver responsible can't be identified but we can try and identify it by enabling driver verifier but enabling Special Pool.
Follow these instructions until you get to step 3, then click Select individual settings from a full list.

Driver Verifier - Enable and Disable

Post back the results.

Can you boot into safe mode with networking?
If so please upload the dump files created.

There are no new dump files.
Check in this directory.


If there are no new ones here then I recommend enabling Driver Verifier with the same settings and keep it bug checking until a dump file is creating.

You don't need the DM log collector every time, just copy the dump files from that directory, zip then up and upload that zip file.

basically keep restarting the PC after every BSOD until it stops?

No, you want to get the bugcheck, then see if it creates a dump file. If not then you'll need to do it again.
There are alternatives but it'll take a long time figuring the problem out.

At the bottom of the blue screen it will say collecting dump information.
When that appears it should create the dump file.

Try it a few more times and if not we'll go in a different direction.
