Good find.

Speccy also does the job well. Alternatively, on the Windows platform, you can use the native System Information utility by entering "msinfo32.exe" (no quotes) In the search bar or Run menu.

I took a look at Speccy, this is what it told me my motherboard is: HP 8114 (U3E1)

To my knowledge, HP lappies have an on-board (Integrated) sound card so to Install a new one, there's three options available.

* In the PCMCIA slot.
* In the ExpressCard slot.
* Via USB (obviously).

Depending on the age of your lappy, It'll either have the PCMCIA or ExpressCard slot. Check which of the two apply and we can work from there.
