No the USB extra ports plug in in the back also has 4 lights on it. They are all green when the computer is working fine, if there is a red light out of the 4 then there is something wrong with your PC and you are supposed to read the manual to figure out what the problem is. I'm not saying the USB thing is giving me problems, I'm saying it's telling me whats wrong with my computer but without the manual I cannot figure it out and I have no idea what to search for in a search engine or anything.
As far as the noise goes it won't happen anymore since my PC won't start up now and just hangs at the first screeen. The noise sounds almost like a song but other than that it's hard to explain really. What kind of sounds would there be that you could explain?
It might be the Processor but who knows, like I said without the manual I can't really figure out what went out. Does that explain the USB thing more clearly?
