The CellFormatting event is sent for all visible cells in the grid. You may have better luck using the data given in the event to change the color.

private void dataGridView2_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    if (e.RowIndex != -1)
    {
        if (dataGridView2.Rows[e.RowIndex].Cells[7].Value.ToString() == "Error")
        {
            e.CellStyle.BackColor = Color.Red;
        }
        else if (dataGridView2.Rows[e.RowIndex].Cells[7].Value.ToString() == "NoError")
        {
             e.CellStyle.BackColor = Color.Green;
        }
    }
}
