Hey I need help with my computer I installed speedfan and played around with it a little and now my computer won't boot up. Obviously I'm on another comp right but I don't know what to do. It seems like I'm not supposed to change fan settings, its as if the computer can only turn on on certain settings. Anyway I don't know where this post should be its originally an hp computer but I've made a lot of changes, recently I changed the cpu fan cause it was noisy. When I power it nothing comes on the screen but the computer seems to turn on. Ok thanks.
