Hi, I've just completed my build, b450 motherboard, Ryzen 5 3600 16gb RAM, old GeForce GPU. Anyhow on startup I get the usual press del or f2 to access BIOS when it goes 'cpu fan speed error' and usb device over current detected, pc will shut down in 15 seconds'. Now, accessing the BIOS doesn't work somehow, afterwards I can shut down the of by pressing alt strg del tho. Anybody got a fix?

Already tried multiple keyboards and all usb ports

I would address the cpu fan error first, is it running, is it plugged in to the correct location?

Thanks for the reply,
I used the one that came with the Ryzen 3600. It is running and I believe it to be in the right place - I had another CPU fan, an older model of my previous build which I plugged in instead, yet got the same error

Run the system with minimal components. Just one RAM and check again. Run it outside of the cabinet and check again.

Did it, still doesn't work. Also took out the Mainboards battery, waited for five seconds and plugged it in again.
