Two BSODS: System Service Exception & Bad Pool Header

May 4, 2012
Reaction score
I recently got these two errors within two days of each other. The Bad Pool Header occurred when I was playing the new game Sniper Elite 2. The System Service Exception occurred randomly while I was skyping with friends and watching youtube. The file below was made with Windows_6_NT_BSOD viewer. It includes the .nfo file and both of the .dmp files as well. Any help would be appreciated

System Specs:
Windows 7 x86 Premium edition
Radeon 6950 2gb Toxic Edition
Intel I-5 750 2.67 ghz Processor
16gb Corsair Vengeance (4 sticks of 4gb a piece)
ASUS P7P55 LX Motherboard

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.
- - The most common drivers are listed on this page: Driver Reference Driver Reference
