Protection over internet for Dummy

["GG" <ghgon@xxxxxxxxxxx>]

Hello Bonjour !

I just connected my computer to high speed internet for the first time
and I am experiencing weird stuff... (screen turn blue withou count
down + error message + computer reboot constantly...)

I  have to admit I have no protection and no clue about what I should
do, if anyone can help me...

I am running windows 2000 server, wha twould you recommand me to do
best?

Thanks and a very happy new year to everyone!
