Raspberry Pi Troubleshooting

Check out Raspberry Pi's Troubleshooting Page for answers to questions such as:

• What is the username and password for the Raspberry Pi?

• Why does nothing happen when I type in my password?

• Why does my Raspberry Pi not start up/boot?

• Why is my Raspberry Pi hot?

• I keep getting a lightning bolt symbol and messages about power...

• My SD card seems to have stopped working.

• I've imaged an SD card with Raspbian/NOOBS, but when I look at it with my Windows PC, it's not all there!
