PS3 to PC Internet connection sharing?

[Dest747]

I had a previous post about iPod touch Internet sharing with my PC, and I had no luck. I recently got a ps3 and also upgraded my PC to Windows 7. It runs awesome, but... no Internet. So:

 

-There is a wifi network in my house.

-My PC only has ethernet.

-My ps3 and iPod touch are both connected to wifi.

-MY PC IS NOT A LAPTOP

-I have a spare Ethernet cable.

 

Can I use either the ps3's or iPod's Internet connection on my PC?

 

Please help.

 

PLEASE!!!
