I also think it has to do with my laptop cam since that is also the name of the camera software, but every time I unplug/plug the laptop BisonHK reports an error (BindToObject Failed), so it may also have to with power management!!

Best practices for resolving BisonHK issues

A clean and tidy computer is the key requirement for avoiding problems with BisonHK. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
