McAfee is a frequent cause of BSOD-s, consider uninstalling it with the McAfee Removal Tool and replace with Microsoft Security Essentials at least to test.

MSE is recommended from a strict BSOD perspective, compatibility & stability compared to other antiviruses/internet security software:-

1. Microsoft Security Essentials - Free Antivirus for Windows
2. Malwarebytes - Free
3. Good and Free system security combination.

Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Please uninstall DAEMON Tools. It uses a driver called sptd.sys which is known to cause BSODs in Windows 7. Uninstall the software using Add/Remove Programs. Reboot the system. Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.

As an alternative, many people recommend the use of Total Mounter or Magic ISO

I've un-installed daemon tools lite, but when I use the sptd.sys uninstaller it says "No SPTD version was detected." Does this mean that when I removed daemon tools the driver was removed as well? Or should I do something else instead?

Sounds like its gone:)

You're welcome.
Post back if there are more BSOD-s and if there are none, you can mark the thread as solved after 1 week of observing. :)
