Question Computer won't turn on after shipping, beeps indicate RAM not recognized

[littlecupcake]

I shipped my PC across country stuffed with anti-static bubble wrap and surrounded by bubble wrap+styrofoam. This worked the last three times I did it, but not this time. Plastic parts of the front panel of my case broke off, and it wouldn't turn on when it arrived.

At first, the CPU and PSU fans would spin, but not the case fans, and orange light on the motherboard blinked with no beeps, and nothing would come on my display. I reseated everything (RAM, GPU, CPU and re-did the cable plugs) and I removed the CMOS battery for five minutes. I will note I also did something dumb - the orange light suggested a RAM issue, so I grabbed some RAM out of another PC to test, not realizing it was DDR3 - I'm not sure how it fit into DDR4 slots but I did jam it in there.

Now, same thing - PSU and CPU fans spin but not case fans - but instead of the blinking orange light I get one long beep followed by two short beeps over and over. My motherboard manual says this: "One continuous beep followed by two short beeps then a pause (repeated): No memory detected." I tried brand new DDR4 RAM sticks and this still happens. The new RAM sticks do work because I put them in another system. Video of the beeps:

System specs:

• Case: Rosewill RISE Glow ATX
• CPU: AMD Ryzen 7 2700X
• GPU: Nvidia GTX 1060-3GB
• PSU: Corsair CXM 650 W 80+ Bronze Certified Semi-modular
• SSD: Samsung 970 Evo NVMe PCIe M.2 500GB
• RAM: Corsair Vengeance LPX DDR4 3200 C16 2x8GB
• MBD: Asus ROG STRIX B450-F GAMING

So, is my motherboard cooked? Could something else explain what's going on? Anything else I can try? Would it be worth even trying to take to a computer repair or is it just done?

Installing DDR3 into a DDR4 slot would most likely cause daMAGE.

1 long and 2 short beeps;

1 long beep and 2 short beeps

When I try booting I get 1 long beep and then 2 short beeps. I googled and it seems to be a video card error, however I tried both my 5850 and the onboard with no luck. Tried DVI and HDMI connections. Anything else I can try or is this a bad board? model is M4A89GTD Pro
