PC powers on, Lights, Fans everything, but I get no display.

[trentendo2002]

I've had this PC for about a year, and it worked fine, one day, when I got home from school, it wouldn't display anything, I still get beep codes on it, the lights on my GPU turn on, all the fans are running, and it's not Power cycling

What I've tried
-New PSU
-Resetting CMOS
-Different RAM
-Different GPU
-New Monitor
-New HDMI cord

My Specs
PSU- Thermaltake Smart 500w
MOBO- IPMMB-FM (Formosa)
GPU- Readon RX 480 4GB
CPU- Intel Core i7 3770

Any help is appreciated, Thanks!

so really you are left with PSU, Motherboard or CPU.

What are the beep codes telling you? They will point you to the error.
Check the motherboard manual to see what they mean.

pull the gpu see if onboard video will post. if there no post try clearing the cmos. if the mb a few years old change the cmos battery.
