        Form2 Check = new Form2();
        Check.Show();

You cannot just close the Form1 as it is the main form, but you can hide it. Use this.Hide().

private void Check_Click(object sender, EventArgs e)
{
    Form2 Check= new Form2();
    Check.Show();
    Hide();
}

[EDIT]

Not sure if this is what is asked. But...

There are many ways to implement navigation between forms, for example:

In Form1:

private void button1_Click(object sender, EventArgs e)
{
    Form2 form2 = new Form2();
    form2.Tag = this;
    form2.Show(this);
    Hide();
}

In Form2:

private void button1_Click(object sender, EventArgs e)
{
    var form1 = (Form1)Tag;
    form1.Show();
    Close();
}
