hello i have a big problem, besides my terrible english

Since i had my new PC (Acer Aspire Dual Core AMD 5600+)
Pardus is so slow... on my old PC it works wonderful, but now it boots a long time.
When i want to install it, it is the same. (Maybe it's ok for an installing, but formerly it was'nt so...)
After the installtion, it boots for a long time, too.
I don't know why, but it is not good i want to have pardus on my PC
And if i want to shut down the PC it is slow, too :-P
I think maybe Pardus cannot avoiding with dual core or so ... but it is only a idea... i haven't a clue
I hope you can help me
