Is your Datagridview using a DataTable as the source.  It would be easier to filter the datatable.  Is the data a string object or a datetime object?
You string statement should look like the following
string strSql = String.Format("SELECT * FROM Computers WHERE StartTime >= #{0}# AND EndTime <=#{0}#", dt.ToString("MM/dd/yy hh:mm"));
{0} is the first parameter which is already a string : dt.ToString("MM/dd/yy hh:mm")
