Hi all,

I'm hoping you can help me with a BSOD I encountered yesterday. I have attached the Sysnative zip file per instructions on the sticky thread, please let me know if you need anything else (I've also saved the MEMORY.DMP file in a separate directory in case that is needed, but it doesn't seem to be automatically included in the Sysnative zip so perhaps it isn't necessary).

https://drive.google.com/file/d/1ih07KcYEOmEiXg9IRvQx-nxhtNOz9rJq/view?usp=sharing

Worth noting that I had some severe BSODs about a year ago that forced me to send my PC back for repairs, which concluded the CPU itself was faulty so that has been replaced. The PC has been running fine ever since, up to yesterday evening.

Thanks in advance!

An Avast! driver (aswbidsdriver.sys) is referenced in one of those dumps...
Code: 
FAILURE_BUCKET_ID:  AV_R_aswbidsdriver!unknown_function
And @SpyderTracks is right, Avast! does cause more problems than it solves. You don't need third-party anti-malware these days.

That said, and taking the other dumps into account, this looks more like a RAM problem to me. The System log also contains a large number of unexpected process terminations, that also suggests a potential RAM problem. We certainly need to get your RAM tested and there are two ways of doing that, one slightly less painful than the other.

You could run Memtest86 to test your RAM, but this will take several hours on 32GB and you won't be able to use the PC during this time. In addition, Memtes86, whilst very good, isn't perfect. No RAM tester can be. A pass from Memtest86 only suggests that your RAM is good, it doesn't prove it to be good. If you want to run Memtest86 here's how...
  1. Download Memtest86 (free), use the imageUSB.exe tool extracted from the download to make a bootable USB drive containing Memtest86 (1GB is plenty big enough). Do this on a different PC if you can, because you can't fully trust yours at the moment.
  2. Then boot that USB drive on your PC, Memtest86 will start running as soon as it boots.
  3. If no errors have been found after the four iterations of the 13 different tests that the free version does, then restart Memtest86 and do another four iterations. Even a single bit error is a failure.
The other technique is to remove one stick of RAM for several days and run on just 16GB. The main advantage of this method is that you can use the PC normally whilst we 'test' the RAM that's still installed. In addition, this method is guaranteed to find a flaky stick. If you get a BSOD on one stick you can immediately swap sticks and run on the other one. This will indicate whether one stick is bad.

Thank you very much!

I will remove Avast and run a memtest overnight tomorrow. I'll also consider the RAM removal method depending on the results of the memtest.

You have to use the official uninstaller, can't do it through windows

Avast! Uninstaller

If you plan to remove RAM for testing then there's little point in running Memtest86 first. However, the very first thing you should probably do is remove the XMP overclock on that RAM and run it at the stock speed of 2133MHz to see whether it's stable there. Only if it BSODs with the RAM at stock frequency is it time to run Memtest86 or remove one RAM stick at a time (I'd prefer the latter).

Hey, sorry for the delayed response, was moving house and had no internet.

I was able to run the avast uninstaller and memtest (which passed with no reported errors). I have been making light use of the PC while offline and it has not encountered another BSOD so far.

Do you still recommend removing the XMP overclock given that memtest passed?

If it BSODs again then yes, remove the XMP overclock and see whether it's stable at stock.

Memtest86 running clean is a good sign, but it doesn't prove that your RAM is good. The only way to do that is to remove one stick at a time. But let's see how it goes now Avast! is gone.
