Now where's the thread starter?
Let me answer his question and this thread can RIP.
1) Depending on your CPU casing, you might need a
screwdriver.
2) remove outer casing, (remove 4-6 screws at the back, if any),
newer casing are just sliding panels might not have screw.
3) look for a PCI slot. A typical Motherboard will have 1 AGP slot
(usually brown) 3-5 PCI slots (usually black or blue).
4) Sound card should go to the PCI slot.
5) the slot might be blocked by a metal cover as part of the
casing. Either you unscrew to remove it or you must wedge
out.
6) if sound card is your only card, try to choose the furthest from
your Video card so the heat can disspate better.
7) after inserting, there is a cable that extends out of your
DVD/CD-ROM, you need to attach this to your sound card. but it is
optional.
your sound card is install... now replace your
casing.
