These are happening randomly. I've gotten 3 in 2 hours now. EVerything was fine yesterday. DMP file is attatched

Several problems

1-sptd.sys used in daemon tools and alcohol. A huge cause of BDOS's

Please remove any CD virtualization programs such as Daemon Tools and Alcohol 120%. They use a driver, found in your dmp, sptd.sys, that is notorious for causing BSODs. Use this SPTD uninstaller when you're done: DuplexSecure - Downloads

You can use MagicDisc as an alternative.

Freeware MagicISO Virtual CD/DVD-ROM(MagicDisc) Overview

2- AVG sometimes causes bsod's as well remove and replace with Microsoft security essentials.

3-Your video driver caused this crash.

When upgrading your graphic driver you MUST remove all traces of the current driver. In order to do that we recommend using Guru3D - Driver Sweeper

When it is removed then download and install the fresh copy.

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: 00000000000ff8d9, memory referenced
Arg2: 000000000000000b, IRQL
Arg3: 0000000000000001, value 0 = read operation, 1 = write operation
Arg4: fffff880048b29e8, address which referenced memory
