System slow/abnormal boot

My english is not perfect, sorry.

I have been trying to install Osx86 on my computer, but never worked perfectly.

When system starts to boot up I have to press the keyboard keys consecutively, otherwise the image freeze and the system cant boot up.

When the system finally boot up, to have a smooth sound, without breaks, I have to move the mouse without stopping(or press keyboard keys very fast). The same happens with the animations (like dock). I have to keep moving the mouse, otherwise the animations are slow.

tested all voodoo kernels. experienced Ideneb, iatkos 7. but had no luck. the problem persists

I have all hardware identified by system.

Can anyone help?
