The most common problems that people face with their Raspberry Pi come down to the power supply they are using. If your Raspberry Pi is behaving strangely, then we recommend that you try a different power supply. A good quality supply is recommended as the Raspberry Pi is susceptible to electrical noise.

It is also a good idea to check whether you have imaged your SD card correctly. It is OK to image the SD card again.

Another common problem that people have when they are setting up their Raspberry Pi for the first time is they select the wrong input on their monitor. When a Raspberry Pi boots, if it cannot find an HDMI monitor attached, it will automatically use the component output. The easiest way to stop this from happening is to make sure that the input on your monitor or TV is set to the correct input before your Raspberry Pi is turned on.
