A device driver problem has caused the system to pause indefinitely (hang). Typically, this is caused by a display driver waiting for the video hardware to enter an idle state. This might indicate a hardware problem with the video adapter, or a faulty video driver.
A kernel-mode process or driver incorrectly attempted to perform memory operations. Typically, a faulty driver or buggy software causes this.
A system thread generated an exception which the error handler did not catch. There are numerous individual causes for this problem, including hardware incompatibility, a faulty device driver or system service, or some software issues. Check Event Viewer (EventVwr.msc) for additional information by looking for Yellow Traingles with an exclamation point or Red X's.
0xD1 errors are usually caused by drivers but they also can be caused by mismatched or faulty drivers.
My first suspicion is that either the issue is with your video card drivers or with your security software. Since Avast is very stable I doubt that is your issue.
1. When you updated your graphics card drivers did you first clean out your old drivers before installing the new ones?
2. What firewall or other security software are you using?
* Please give us your hardware specs including make and model of your motherboard, RAM type and how much you have installed, video card, etc.
