biggg trouble.

hi, i'm havnig a trouble with network in vista.
my situation is kind of hard to understand, but
i know what i'm talkin about, so please be patient with me.
on the right bottom, if i put my mouse on the network icon,
it basically says that the window has failed to connect, and that
the information is invalid. (my labtop is in korean language, but i briefly
translated)

and as it is disconnected and the info is invalid, it has the X sign on it
in red.

but my internet works. my local one is connected, and so is my wireless.
(both works)
i know this because the internet works, and i looked at the driver setting by
rightclicking 'my computer' and checked my drivers from 'manage my drivers'.

but wat bothers me is that i cannot get access to network.
and i mean the folder network.
i cannot go to control panel, and access to network.
i cannot right click the network icon on the botttom right and access to the
network.
when i try to, new window (the one thats supposed to display the network
settings) freezes and comes out blank. i have to use control + alt + delete
to stop the freezing.

other examples would be when im downloading something
When i try to download soemthing and choose where to download it on,
if i click on network, that window freezes. it simply cannot open anything
about
network.

please help.....this is frustrating. i dont know whats wrong. its not a
virus. i know it.
and ma internet still works...but i cannot change any settings through it
because
the window simply freezes when i rightclick the network and click property.

please help!
