I have a Raspberry Pi 3. Until yesterday night it was working perfectly then before I slept I switched off both my monitor and my Raspberry Pi 3. Today when I woke up and turned them both on I notice that the monitor was not showing anything and my Raspberry Pi 3 was showing a red light but not the green light as it showed before. I thought that it was a monitor problem so I tried another monitor with a different HDMI cable but still no booting started. My OS is NOOBS.

The problem is that since I have switched on the Raspberry Pi 3 I notice that no green light shows up along with the red light. Only one red light shows up. this means that I am getting power but the Raspberry Pi is not booting. It has only been 3 months since I bought my Raspberry Pi and I don't want to take it to a repairing shop. Please tell me what should I do so that the green light comes back on my Raspberry Pi and everything turns back to normal as it was until yesterday and I can start working on my Raspberry Pi 3 again.

    If you want anyone to read your question you need to put some effort in grammar and structure.

    Was it shut down properly? I would try a new image on a new SD card to rule that out as an issue.

    No green light is what will happen if you power up with no SD card inserted. If it happens with a card in, most likely the card is not formatted properly or has become corrupted.

Replace the SD card.

Always have a spare with a known working OS. They aren't expensive and it doesn't have to be large or with a fast read/write speed (class 4 or 6 is fine to test)

  • I was in a hurry. Actually my grammar is quite good. During the time when I was writing the question I was feeling very tense and so I wrote the whole story and some of my grammar went wrong. Commented Mar 7, 2018 at 12:10
  • If you don't mind checking where you comment! My answer did not bring your Grammar into question. There should be 'add a comment' just below the critique above. :-) Commented Mar 8, 2018 at 13:37
