Need help with stupid PCheatsink!

[Dan]

I want to silence my PC, I have bought a new heatsink with fan from Arctic cooling, but I don´t know how to remove the old one.
I should pull away the lever at the socket to release the heatsink right? whan I read the motherboard manual i get the impression that I should pull the lever outwards and then up,but how come there is so much resistance?
Another problem, the current heatsink is wider than the CPU-socket..... :-?

What CPU?

Sorry, it´s a Duron.
The new heatsink is atually smaller than the old one and it fits I have checked, the problem was removing.
Toward th CPU, got it thanks.
