Hi all, I have an issue with the OS not recognising my phone. 

I have a nexus 5 and it was interacting normally with the OS up until I used my PC's hot swap port to get some files off an old hard drive. 

Since putting on that hard drive (and removing it), windows doesn't recognise my phone when it is connected. The phone knows it is connected, and other computers (e.g. my work PC) recognise when the phone is connected, but not my main desktop. The phone does show up in safely remove media box on the start menu, but not in file explorer (see attached screenshot) and I can't move files on/off the phone.

I've tried putting the hard drive back on and labelling it with a different drive letter, but my phone is still unrecognised - any thoughts to fix this?
