So my elegoo uno just randomly stopped being able to upload anything. I get the 'can't access com 3' on one computer, and multiple attempts of 'not in sync' on the other computer. How do I fix this? I have tried with different two cables, no joy. I have tried on mutliple usb ports, also no joy. I have tried pressing the reset button, no joy. Please help.
When you press and release the reset button, dos it quickly blink 3 times?
