Dead USB and Ethernet ports

Hey,
The USB ports suddenly stopped working while I was installing retropie on my pi 3b....
The Ethernet too doesn't work....
I read a few posts and checked the voltage between PP3 and PP27 and didn't get 5v(almost 0)...
BTW I was using a 5v 2A power supply and it had worked for about a year pretty well....

So is my board fried? Is there any way to ssh into the pi without the Ethernet port(I have WiFi but don't know how to set it up without a mouse and keyboard)

Any help is appreciated, thanks!

Get a new SD card and try installing Raspbian Desktop or Lite from https://www.raspberrypi.org/downloads/raspbian/

If there was still no ethernet when you burned a new SD card and booted it, things look bad for your Pi.
But just possibly the two USB ports furthest from the ethernet socket might still work, they have a different controller chip (or something, they work seperately from the othertwo and ethernet port).

Incorrect info, on RPis which have more than one USB Port as well as an Ethernet Port, they are all connected to a single USB2.0 Chipset, pre 3B+ it was a LAN9512/14:

Is this a 3B+? If so, there are two USB hubs in the onboard chip. It looks like one pair of sockets and the second hub are connected to the first hub. The other pair of sockets and the Ethernet are connected to the second hub. So a second hub internal failure could result in no ethernet and the loss of two USB ports.

Not saying this is the case here, just that it might be a possibility.

The OP talked about using for over a year in his initial post, hence why stated pre 3B+ :D
