The crash dump and blue screen happens because windows was using the software at the time, and no doubt the driver for Thx pro studio was in use by windows at the time.

It was a running task or back ground service or task in windows.

If you want to speed your system up, then the likely cause to it being slow will be down to the amount of system ram you have fitted to the system and how much windows is using of it it`s self and what is free for other programs to run.

How slow it is at loading and doing tasks and having a lack of free system ram, when trying to run multiple programs at the same time in windows is the cause.

Because once the physical amount of free ram is used up windows will switch to what we call virtual memory mode.
Where it will use a set portion of the hard drive to temporally store data from the system memory to create more free space but use the hard disk drive of the system.
A hard drive is about 1000 times slower than system memory in speed when it comes to swapping data to and from main system memory.
It`s like a juggling act windows does when low on system memory.
And a place where you don`t want to be.

To free up memory.
You should limit the amount of programs set to auto run after windows has loaded into system memory.

You can do this by clicking on the search box in windows.
And typing msconfig in the search box.

Select the result shown.

Click on the start up tab in the new box that opens. untick all of the check boxes set for programs to auto load or run after windows has loaded.

Click on apply and then ok.

Restart the system.
And it will conserve more memory for other programs to run.
If you list is long in the start up listings it will save a lot of memory freeing it up.

If you restart your system, but keep getting the blue screen of death while windows is loading.

Restart the machine.
Keep tapping the F8 key on your keyboard till you get to the windows Os loading options selection page.
select safe mode.
let windows load in safe mode.

When loaded simply go to system restore of windows.
Select the restore point where or before you uninstalled the THX program.
Restore the system from that check point.

the system will restart and windows will load again without the blue screen error.
