Everything is fine now.
I think i did not set my swap partition before i install the Slackware. i reinstall everything by setting up the swap partition first then follow by system file installation.
It run smooth right away till the xfce. Now wicd installed and started my browser on internet.
It solve my screen freeze. And i am also able to use kernel 18.104.22.168
Again i don't really know how it solved. It just happened like that
What is the reasons when i first start the Installation CD, it said my CPU does not have the PAE features? I really don't know yet, but most important now is I am ON with SW -current.
If anyone can explain it to me will be very much appreciated.
