So overclocked my ryzen 5 2600 on a gigabyte b450m mobo. I overclocked it to 3.8ghz from 3.4ghz base clock the voltage is set to auto . My pc seems to be working fine until one day i opened it and there was no display, i tried troubleshooting it by resetting the cmos, cleaning the ram, removing the gpu and putting the hdmi cable directly to the mobo nothing seems to be working so i suspected that its the motherboard and also i can feel electricity when i touch some part of my case (my system is new btw i bought it 15 days ago parts by parts) im asking that what did i do wrong?

Specs:
R5 2600
Rx 580 4gb auros
16gb ram teamforce
Ssd/hdd
B450M gigabyte
600w psu hyper k
I hope i get an answer. Ty♡
