Since you know it is a conflict with Cakewalk Sonar at least in part then removing it if possible
would be a start. Also you can troubleshoot the issues using these methods.

1. Last Known Good Configuration - repeatedly tap F8 as you boot.

2. Do a thorough check for malware - see below.

3. Check for updated drivers and BIOS - see below.

4. Uninstall the last install - you already know what that is.


If you need to check for malware here are my recommendations - these will allow you to do
a thorough check and removal without ending up with a load of spyware programs running
resident which can cause as many issues as the malware and maybe harder to detect as the

No one program can be relied upon to detect and remove all malware. Added that often easy
to detect malware is often accompanied by a much harder to detect and remove payload. So
its better to be overly thorough now than to pay the high price later. Check with these to an
extreme overkill point and then run the cleanup only when you are very sure the system is clean.

These can be done in Safe Mode - repeatedly tap F8 as you boot however you should also run 
them in regular Windows when you can.

Vista and Windows 7 love updated drivers so here is how to update the major ones.

References to Vista also apply to Windows 7.

This is my generic how to for proper driver updates :

This utility makes it easy to see which versions are loaded :

DriverView - Free - utility displays the list of all device drivers currently loaded on your system.
For each driver in the list, additional useful information is displayed: load address of the driver,
description, version, product name, company that created the driver, and more.

For Drivers check System Maker as fallbacks and Device Maker's which are the most current.
Control Panel - Device Manager - Display Adapter - write down the make and complete model
of your video adapter - double click - Driver's tab - write down the version info. Now click UPdate
Driver (this may not do anything as MS is far behind certifying drivers) - then Right Click -
Uninstall - REBOOT this will refresh the driver stack.

Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd party
with their own software and drivers and any other major device drivers you have.

Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then Device
Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their latest versions. (Look for
BIOS, Chipset and software updates at System Maker's site while there.)

Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN - REBOOT after
each installation.

Always check in Device Manager - Drivers tab to be sure the version you are installing actually
shows up. This is because some drivers rollback before the latest is installed (sound drivers
particularly do this) so install a driver - reboot - check to be sure it is installed and repeat as

Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check
manually by model.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

Installing and updating drivers in Windows 7 (updating drivers manually using the methods above
is preferred to ensure the latest drivers from System maker and Device makers are found)

If you update drivers manually then it is a good idea to disable Driver Installations in Windows
Updates, this leaves Windows Updates ON however it will not install drivers which will usually be
older and cause issues. If Updates suggests a new driver then HIDE it (Right Click on it) and then
go look for new ones manually if you wish.

Also, from the above information, the driver that is causing the crash is the TFSysMon.Sys.

The TFSysMon.Sys is a driver for Threatfire.

You could try uninstalling Threatfire and see if the issue resolves.

That seemed to work in the following link:
