Well I have to write this from my Ipod and its horrible self correct which I have to keep fixing. But whenever I boot up my computer, instead of a normal beep, it's a 3-4 second long beep, which stops for about 5-6 seconds and repeats till you switch off the computer. I looked it up and according to sources, it says it's a memory error, something to do with RAM. I didn't download anything recently so I don't think it was a virus. Is there a way I can fix this? Also, the computer says "No Input Signal, Power Saving" if you turn on the screen. I'm really annoyed with this.
