I purchased a preloaded Noobs/ SD card with Jessie when I bought my Pi 3. The first boot up the Drop down menu looked normal. There were preferences and all of the Libre programs were also available. In preferences there was no WiFi setup to select and that is where the trouble started. I was clicking through other preferences looking for a means to set up WiFi and the System Hung. I had to reboot, After ReBoot none of the menu options were available. I have searched for the Desktop and Applications from the console and nothing seems to be there? This is kinda weird. I am ordering another SD card Adafruit, and have downloaded one here as well, but am kinda wondering if this is going to be a persistent problem?
When I started the pi up the first time I did not realize that I only had a 1 amp PS. Would that make it act weird? The first time it booted it looked fine except for their being no WiFi config in the Preference section of the GUI.?? I did buy a new 2.5 A power supply so I will give it a try as soon as that arrives.
Any Ideas while I await my power supply would be nice.
