Help Me!

[Micah.T]

Hello there! I have just recently built myself a computer! Everything was going swimmingly, until I switched cases... When I attempted to boot up the computer in the new case, everything seemed to be on, all the fans were spinning, and I have re-seated just about every component in the computer! None of the rear outputs are working, along with the HDMI outputs not working. Me and my friends are completely dumbfounded as to what the issue could be! Please help? My specs are as follows;

PSU - Rosewill Hive 750S   CPU - AMD Ryzen 1700x   GPU - MSI Armour 2x   Motherboard - ROG Strix B350-F gaming   Case - Haf XB evo Lan Box by CoolerMaster

Pull the CMOS Battery for at least 10 Minutes and try again. Unplug power with that reset.

Which one dropped the mobo on the floor while moving it from one case to another? If reset doesn't work ebay is your last resort.

Unlikely, but it's possible that lack of proper grounding resulted in a static discharge that ultimately killed your mobo during the case transfer.
