                If DataGridView1.Rows(a).Cells(0).Value = DataGridView1.Rows(b).Cells(0).Value Then

                    MsgBox("Value same, its will delete" & DataGridView1.Rows(a).Cells(0).Value)

                    ' then, remove the row
                    DataGridView1.Rows.Remove(DataGridView1.Rows(a))
                    a -= 1
                End If
            Next
        Next
    End Sub

Setelah selesai, langsung saja di run "F5".

Penjelasan :
Jika kita memberikan input yang sama pada cells(0) datagridview atau dengan id ("Nama") atau dengan kata lain jika memiliki nama lebih dari satu  maka akan ada peringatan sebelum menghapus row paling bawah dari row yang sama. dengan menggunakan perintah Rows.Remove().
