Getting a Blue Screen of Death Occasionally

During the last couple of months my computer has been crashing occasionally. Today I decided to create a minidump to see what is going on. I would really appreciate it if you guys can help me out in how to fix this problem. Thank you.

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
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 kernel debugger is available get stack backtrace.
Arguments:
Arg1: 00000004, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: 8aced055, address which referenced memory
