Hi,
Bugcheck 1A is often associated with faulty RAM as the bugchecks actual meaning is a severe memory management...

Uninstalled the update and it doesn't find any errors now. Now my question is, how do you find this stuff? Just years of experience?

Just a hunch plus that update has been causing issues for a few users. Let's just say it was a lucky guess aided with a bit of experience.. :) Anyway I'm glad to hear your error free now and apparently Microsoft have re-released that update so now it doesn't bork users machines. If you see it being installed again just be careful and keep your eye on it. At least you know now what the issue might be.

Hey,
it looks like CMUACWO.sys was the cause of the bsod and this relates to a C-Media USB audio device driver. The one your carrying is dated 2013 and a little googling found this 2014 version although I'm not 100% sure it's compatible:
http://drivers.softpedia.com/get/SO...io-DAC-Device-Driver-7013-for-Windows-7.shtml

Any problems installed the driver then post back with the make and model of the headset involved please.

Ok sounds good.. At least you have an idea where the problem may lay. Hope the build goes well and of course post back regarding your own system if need be.

The drivers for it are located at http://schiit.com/products/modi-2. Could it just be something with their drivers that causes it?
I'm unsure but if there isn't an update available you could try updating your chipset drivers as well as re-installing the device driver again in case it's become corrupted.

I looked at the drivers again and they are labeled as C-Media even though Schiit provides the drivers from their site.

Are those drivers I posted above any good? Maybe worth a try if they are a later version but perhaps only if the bsod returns? It's up to you...

I'll try em if the bsod happens again. I'm not sure of the date on the drivers off the Schiit website.

My friend had a bluescreen. I was deciding on helping him out. He says it doesn't happen a lot but I told him I'll try to get a word for him. Here's his files.
