My mackintosh sometimes does shut down, some times it doesn't

[pluda]

Hello,

 

I've installed 10.5.6 retail on my netbook and then updated via software update to 10.5.8.

The computer is ok, better than it was when I had 10.5.2 or 10.5.6 from Ideneb.

 

In general everything works, except of course the wirelless, but I don't use it anyway, so no problem.

 

Now the big deal, most of the times I can't shut down the machine, when I do it, the process starts, all icons from desktop disapear but then it stays with the background image and nothing happens, I've then to force shut down pressing power key until it does shut down.

Ore strange, is that sometimes it does shutdown...

 

Also, I don't find any compatible chameleon, I wanted to have one, so I can install winXp.

 

I've tried all the kexts sugested in this forums, but none solved this problem.
