Alright so I have had my other PC for a few weeks now and just the other day a notice popped up saying my copy of Windows wasn't genuine (It is, It only said that after i installed the updates). After a few days of that notice, I thought it would go away after a while. One night my brother shut the computer down and the next time I start it up, the internet dosen't work anymore. There is a little ! next to the internet sign and it won't open webpages either. Thinking it would fix itself after a while, I left it. It still dosen't work so today i brought it up from downstairs (whole house is networked) and plugged it straight into the Router. It still dosen't work and I don't know why. Any clues?
