Try using your tablet without the driver and check if you still experience the lag and hear the reconnection sound.
Properly uninstall the current driver you've installed, unplug your tablet from your computer, and connect the tablet again.Try to use a different USB port on your computer.Hi Mustafa.akbulut, may I know the tablet driver version you installed on your computer? And does the tablet driver continuously show 'Device connected' whenever your pen can't draw?
