Pentradragon :
Building my first gaming oc and all of the fans won't work including psu gpu cpu cooler. Could this be because of some bad ram
You need to list all your parts, I would double check the connection of the power switch on the case and make sure it's in the right spot. Also make sure the power supply switch on the back of the power supply is in the on position.
All of the fans not working or some of them?
