Hello my names David I am 16 and recently built my first computer, everything went fine at first no problems turned on fine, But when it boots up one of the power buttons on my case flashes red. The computer still starts up and I began to try to install my windows 7 on it. Everything went fine until it was asking me to add my hard drive/ partition it but it couldn't detect my hard drive and I don't know what to do, I've been checking to make sure I put it together right everything's screwed in good and has the correct cables plugged in and according to my manuals I've plugged everything in right and I am out of ideas. Does anyone have any suggestions?
