full system spec? include make and model of the psu

https://asrock.com/MB/Intel/B365M Pro4/index.asp#CPU
did it have the bios version for that cpu?

Intel i5 9400(brand new never used)
Asrock b365m pro 4 (brand new never used)
Nvidia gtx 1060 6gb
Be quiet pure power 10 600w psu
Toshiba sata hhd 1tb
Samsung evo 8601tb(brand new never used)

I believe the bios version is compatible with the cpu, the cpu lever thing was pretty hard to press down could i have messed it up? I heard a little cracking sound i looked it up and other people seem to have had the same sound with no issues, maybe ive not put some of the cables in properly?

Also just incase you were wondering i was using an anti static wrist strap the whole time, its been hot in UK today so ive been working on it pretty much naked so no chance for a static build up aswel as working on the kitchen side. Made sure to hold the mobo by the heat sinks and edges.

Im going to try again tomorrow and try all RAM slots singularly, try the CMOS reset thing, remove everything and then re assemble it outside the case, try VGA input/output (im sure i have a cable somewhere), would i need to buy a speaker for the mobo to hear it beep? Not seeing any leds on is kinda worrying..if the mobo even has leds

Check your cabling into the PSU. Sometimes it doesn't work if the cables are not all the way plugged in. Also, you won't get beeps without installing a speaker/buzzer on the board near the front panel pinouts.
