There are a lot of things wrong++. But you get started on fixing it with:

        if (sw == 0) pictureBox1.Invalidate();

Maybe you should create a Method:

private void redraw()
{
    wrong++;
    Graphics g = CreateGraphics();
    Brush b=new System.Drawing.Drawing2D.HatchBrush(System.Drawing.Drawing2D.HatchStyle.Cross,Color.White,Color.Black);
    if (wrong == 1) g.FillEllipse(b, 250, 125, 30, 30);
}

and You can use it wherever you want

private void pictureBox1_Paint(object sender, PaintEventArgs e)
{
    redraw();
}

and

...
if (sw == 0) { redraw(); }
...
