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.
0x000000BE: ATTEMPTED_WRITE_TO_READONLY_MEMORY
A driver attempted to write to read-only memory. Commonly occurs after installing a faulty device driver, system service, or firmware. If a driver file is named in the error message, try to correct the problem by disabling, removing, or rolling back the driver.
0x0000008E: KERNEL_MODE_EXCEPTION_NOT_HANDLED
A kernel mode program generated an exception which the error handler didn’t catch. These are nearly always hardware compatibility issues (which sometimes means a driver issue or a need for a BIOS upgrade).
I`m fairly certain your problem is caused by a faulty graphics card drivers.
Uninstall your graphics card drivers and reinstall with the latest version from the ATI website.
