1st build PC. I have installed an Asus h110m-a/m.2 motherboard, intel g4400, 600w psu(which i am replacing with 450w 80+), have a 1 TB HDD, and a DVDRW, everything is all set up and lights come on and everything powers up. no boot up sounds from things, onboard speaker makes no beeps. but everything powers up and i have no display going to monitor. Plz advise. everything is in a rosewill redbone tower. still waiting to recieve the video card and RAM.
