can anyone help me i need audio and usb drivers for my emachine 220 cheers

Finding drivers for that takes knowing the exact manufacturer and model # for each part you want a drivre for. Once you have that, it may not be too hard to get the drivers. Lavalys.com has a program called Everest Home edition, which you can download free and it will give you your hardware info.
Then you may be able to go to the site of the maker, or go to downloads.com and find the right driver for it. No guarantees about this being free, but it does happen, especially concerning the sound card driver. Good luck. Been there, done that.
