Question Start up error won’t boot black screen

[Robstar1]

Hi, I was wondering if someone can help me I recently installed new motherboard ( gigabyte x670 x ax ) a new cpu amd ryzen 7 7700x , new ram ( fury beast) , just a old graphics card GeForce gtx 1060 , it has been working fine for the last 7 months then all of a sudden windows started to play up and mouse sometimes stopped working and keyboard also they both stopped lighting up too so I had to hardboot it . Then windows was trying trying to fix itself and I accidentally unplugged wrong plug which was computer and it’s not turned on since . All fans start to spin cpu fan spins then 30 seconds later the cpu fan slows down or stops but other fans keep going . I changed psu to 800w which was 650 and still nothing any ideas please I’ve tried everything?

Did you just say you unplugged the power connector from the wall or am I not reading the grammar in this post???
