Windows 7: BSOD while watching videos, or talking on Skype

31 Mar 2012   #1

Windows 7 Ultimate x64
BSOD while watching videos, or talking on Skype


I seem to be getting a BSOD every once in a while. I don't understand why it happens. It seems to happen occasionally while I am doing various things on the computer. I might be watching a video, or maybe just talking on Skype.

I attached the files asked for, and included a picture of the BSOD. However, it's very low resolution (my apologies).

Edit: This computer was recently reformatted (a couple weeks ago). It appears to have been the cause, since before the reformat I never experienced this. Also, it's Windows 7 Ultimate x64.

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.

How To Find Drivers:
- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.
