I bought a new wirless card and it shows up on Device Manager and it can see networks but i cannot connect to my own. I got it to randomly to work but it showed a red X but still worked which was strange. After a restart its doing the same again and i cannot connect

. One more thing atm my cpu temps are jumping everywhere constantly like crazy never see this before, sometimes it goes from 29c to 41c but ites really fast there moving all the time
