I was working in Visual Studio 2012 when my antivirus turned off and my windows defender turned off. I started shutting down all my applications so I could reboot when I got the BSOD and the Quota Underflow message. I have grabbed all of the dump files and I am looking for some help. I have not installed any software or hardware recently. I did try to upgrade to Kaspersky 2014 and that consistently gave me BSOD. I had to restore from a backup (Windows Backup Server), so it was a clean drive restore. I have had no problems for over a week, but now this has happened and I am curious what the cause could be.
