Solved: 5 beeps and yellow lights at startup

I have a HP Envy desktop computer running Windows 8. When I try to power it on I hear five long beeps and the on/off light flashes yellow. The computer is one month old! Can someone tell me what the beeps mean and how to fix this? Please make explanation simple as I am a senior citizen and don't know much about the inner workings of the computer.
Thanks for your help!
