Hello,

We're sorry to hear about the trouble you had here!

CNET TechTracker is a pretty non-invasive application - at its "worst" it just utilizes some of your system resources to process its scan. It does not alter your video and sound settings at all. What I would do is look to the other circumstances around the time that you installed CNET TechTracker.

Examples:

* Were you having a system or software issue before uninstalling TechTracker?

* Did you install any updates from TechTracker? If so, what did you update, and could this be affecting your sound or video?

* Were there other installations or updates involved at your last reboot, such as Microsoft system updates or something relating to your drivers?

We would be happy to discuss this more - to contact our technical support team, please open a support ticket here: http://cnet.custhelp.com

Regards,
