Hello,this is my first pc build. I have almost all new components. I bought the Intel i5,the Asus gryphon Z97 armor edition and a new power suppley from Corsair the CX500.I was careful while connecting everything,where I did it,how etc.. And so I went to start it and nothing happens on the screen but the computer is running,fans and everything,plus 3 red lights blink and the the BOOT DEVICE stays on. I have a couple of RAM sticks,tried them all and on every slot,I have tried booting the comnputer without any hard drives,I have tried unplugging my graphics card and using the onboard one, I have reassembled the computer,check for loose screws and stuff,lared the cmos by battery and by pins,then i took out the i5 fan and cleaned the processor and put the paste on again. Tried then starting the computer and for the first time it got just an image that said TUF(asus symbol) and the it turned off again. I really dont know what to do anymore,been trying this for 5 days now,losing my mind. If anyone can please help I would be very thankful beacuse this is driving me insane a little.
