I’ve been using the board for two weeks with the same computer and first, everything was ok (board+sound etc, connected with USB cable + VGA cable).
Then,one week ago, when I turned on the sound on the board, my computer froze + the pen wrote lines instead of letters.
Now, another problem: the sound from my computer works on the board but the board says “no source found” and I can’t see the screen of my computer on the board. The computer says Activboard is active but nothing on the board. Moreover, my computer tends to freeze or be very slow when I connect it to the board.
