Nexus 4 and 7 won't connect to Windows PC
I have a Nexus 4 Kit Kat 4.4.2 and a Nexus 7 Kit Kat 4.4.2. I also have a Microsoft Windows 7 Desktop computer.
In the past I was able to connect my Nexus 4 phone and Nexus 7 to my Desktop computer with no issues and swap files to the Desktop. These files were usually music MP3 files. However I was able to swap what ever I wanted over.
Today when I connected my Nexus 4 to my Desktop I kept getting error messages every second saying installing drivers or pop up screens asking what to do such as open file. Occasionally I would see Nexus 4 as portable storage but it would vanish within a second. I would also get notification noises every couple of seconds as well.
As far as I am aware I have:
USB debugging ticked
USB computer connection Media device (MTP) ticked
This is all very confusing and frustrating.
As far as I can tell my Desktop, Windows 7 is up to date and that my computer tells me that I have the correct drivers for the Nexus 4.
I have just connected my Nexus 7 to my Desktop and got the error message unknown device. Up till today, I never had a problem with my Nexus 7, but its been a couple of months since I connected them to my Desktop computer.
Any help would be much appreciated.
As an edit
I connected a Gingerbread phone and that would NOT connect to my Desktop
However I connected an ASUS TF300T Jelly Bean 4.2.1 and that connected first time with no problems
