As an amateur computer person, I have always wanted to build my own computer. And today, I finally have. I have it all set up with all my used parts and I turn it on. BEEEEEEEEEEEEEP. It does that for about 5 seconds and than stops. After about 2 seconds, it starts again and goes BEEEEEEEEEEEEP where I promptly turn it off. Ik the beep could be due to a failing component. What should I try?
