So I have just built my new pc specs:
Amd ryzen 1300x
Corsair vengeance 8gb ddr4 2666mhz
Msi 350m gaming pro
1060 6gb
1tb wd
Stock amd cooler
Corsair VS 450w
Anyway I completed the build and turned on the pc and it booted to the bios I made sure everything was correct and exited the bios it just went to a black screen so I investigated and found out I didnt plug the hdd in (The hdd is an old hdd I have been using and forgot to format it before I installed new parts. This maybe the issue) so I powered off the pc plugged in the hdd to a sata port and powered it back on it just sayed HDMI NO SIGNAL. I have tried reseating the ram and gpu. I have tried switching hdmi ports everything. One more worrying fact is before I plugged the hdd in, the keyboard worked and it lit up but after plugging in the hdd the pc turns on and the caps lock key light wont light up but the keyboard lights still come on :/ I read somewhere that this is a sign of a pc not posting so idk if it is bad or not.
Any advice is welcome.
