I have been trying to install rasbian on my new pi 3b+ computer. But it keeps crashing and comes back to the main screen again.
Not sure what is the error and not sure how to fix this issue
It is unlikely the volunteer helpers here can help unless you give more detail on which to base a response. What is it that 'keeps crashing'? Are there any warnings or messages? What exactly is 'the main screen' you are returning to - is it the NOOBS Recovery Console?
Any pointers to help me diagnose the issue
There is a Troubleshooting guide in Issue 60 of the MagPi magazine which you can access for free online. https://www.raspberrypi.org/magpi/issues/60/
The Raspberry Pi Foundation have a Troubleshooting Guide on their website: https://www.raspberrypi.org/learning/tr ... ing-guide/
These forums have a post which contains all the information currently available about getting an RPi to boot: "STICKY: Is your Pi not booting? (The Boot Problems Sticky)" at viewtopic.php?f=28&t=58151
Maybe your power supply is inadequate, or connected via a poor cable.
Maybe your microSD card is fake, failing or faulty?
Maybe you have not pre-formatted the microSD card correctly?
The official Raspberry Pi Foundation download and documentation for the NOOBS Installer is here: https://www.raspberrypi.org/downloads/noobs/
Unless you have a specific requirement for the facilities of the NOOBS Installer you might find that a direct installation of Raspbian, as documented here, would work for you? (Or it might confirm that it is your hardware, not the Operating System installation that is the problem.) https://www.raspberrypi.org/downloads/raspbian/
