heyy i have 2 big problems, and i hope some1 here could help me with that.

the first problem is my laptop: it wont go on internet/msn anymore :S
The connection isnt the problem becaus Xfire does work.
So i figured; it must be the firewall? but that didnt do any good either :o

2nd problem is my pc...
since yesterday it has the habbit to shut down for no reasen at all :S
it apears to only happen when i play 'big programs' like Rakion (mmo) and Roller coaster tycoon.

does anyone know how to fix this?
