[SOLVED] New PC no boot up or beep codes

[tybarreto34]

Mobo: msi krait gaming 3x
Cpu: i5 7600k
Ram: ddr4 2x8 3000mhz
PSU: EVGA 750 bq

Put a new computer together today with a power supply that was working this morning. Boot up and everything came to life but no display. Went over all cabling make sure everything was in properly. Boot again and same result. Everything is lighting up and running but no boot up or beep codes.
Stripped everything down to PSU, Mobo, cpu, cpu fan. Turned on with a screw driver and same result. I then swapped out parts that worked as of this morning.
Mobo swapped- gigabyte ga-h110m-a
Cpu swap- i5 6400
Ram- 2x4 geil pc4-19200 (idk only markings on it)
This set up worked this morning but failed to boot up now.
Took everything out of the case thinking maybe the new case was messing with things. Put everything on top of anti static bags. Same result.
I believe the PSU went faulty some how and I need a new one but any other ideas before I jump out and buy a new one

no speaker=no beeps.

canned diagnostic speaker rant: speaker making 101
The diagnostic speaker is the motherboards main diagnostic feedback device.
the motherboard may be telling you where the problem is.
my speakers have this plug

I use lamp wire but any stranded wire will do. literally any stranded wires. strip one end like so

attach the stripped end into the speaker spring clips on the speaker.
the other end of the wire should be trimmed like so the semi strip

by doing a semi strip the wire case is now the socket.
plug one wire to the first pin, and the second onto the fourth pin.
power on the system and listen for beeps
end canned rant
