The following code will give you CPU ID:

namespace required System.Management

var mbs = new ManagementObjectSearcher("Select ProcessorId From Win32_processor"); ManagementObjectCollection mbsList = mbs.Get(); string id = ""; foreach (ManagementObject mo in mbsList) {     id = mo["ProcessorId"].ToString();     break; } 

For Hard disk ID and motherboard id details refer this-link

To speed up this procedure, make sure you don't use SELECT *, but only select what you really need. Use SELECT * only during development when you try to find out what you need to use, because then the query will take much longer to complete.
