I am having the following issue, I lose connecting to Pi around 3 minutes after it boots and the only remaining LED lit is the red one. It appears to unresponsive to ping, ssh etc. Reading the troubleshooting I don't have access to a multi meter at the moment to test the power supply. (PSU is the one from RS). I also never appear to get a HDMI output at all, not even during boot. If I check the logs it seems to be restarting?

Since I don't have a multi meter too hand, what else can I check, FAQ says to wipe the SD card and start again. This is the SD card with the OS already installed from RS.
