how can i find what song card is made for my pc
Do you possibly still have the CD's that your computer came with? The sound drivers needed for your computer specifically are given to you on the Motherboard disc that you receive on purchasing your pc. If you don't have this CD, you can use a program called EverestHome ..... this can be downloaded here. Alternatively, you could click Start > Run > type "dxdiag" (without the quotation marks) and then look under the sound tab.
Hope this helps
