Two problems

1-Avast. Remove and replace with Microsoft security essentials

2-ataport.sys (part of the OS).

Please run a system file check to verify and repair it and the other OS files. Let us know the results at the end

SFC /SCANNOW Command - System File Checker

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.
Arg1: 9ec1ba48, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, bitfield :
    bit 0 : value 0 = read operation, 1 = write operation
    bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 82a588dc, address which referenced memory

Debugging Details:

WRITE_ADDRESS: GetPointerFromAddress: unable to read from 82b82718
