nrf52840 - can't find device on windows pc

[Chalad]

So I recently purchased an nrf52840 pdk and was following nordics getting started guide. however my pc will not detect my board when i plug it into the usb. When i plug the board in the led 1 lights up and led5 starts flashing rapidly. Any ideas as to what could be the issue?

I've been having a similiar issue.  I believe I have J-Link installed, yet to spite the board starting up correctly (LED5 fast blinking, LED1-4 pulsing depending on BTN pressed), it does not appear in File Explorer as a JLINK removable device.  I have the bin file, but no where to put it, as I cannot get the BOOTLOADER to appear either.  Is there a driver I am missing???
