Vista won't shut down and Touchpad problems, are they related?

[Sandra Seventeen]

Hello, i'm having some problems with my Acer Aspire 5101 Laptop.
I upgraded to vista about 1 ½ months ago and everything has been working
just fine, but the other day some problems occured;

1, the computer does not shut down entirely it says "logging out" until I'm
forced to shut it off manually.
2, the touchpad has stopped working, or, I can use it for about five
seconds, just after i've enterd my password but then it just freezes. tried
uninstalling the drivers then re-install them and looking for updates both on
the Acer homepage and the Synaptics homepage
3, Msn doesn't work, when i click on the icon nothing happens and then when
i try to re-install it it says that it's alredy running. Also LastFm doesn't
work, similar probs there

Some months ago, after connecting my PC to a projector my Synaptics touchpad
stopped working, but after that, the computer went off to tech suport and it
got fixed. Since then i have upgraded to Vista and downloaded new driver ect
and everything has worked great until this monday or tuesday..

Extremely greatful for help!

Hi,

I had to get a patch from ACER for my MSN to work but i'm still having the
same problems with trying to reboot or shutdown. Acer said they are not aware
of any issues - but they also mentioned it could have something to do with
windows xp driver issues.....

Cheers
