Hello,
My raspberry was working fine for 5 months but yesterday, during a work SD card became unavailable (I could not save the file I was working with) and the OS collapsed. About 8 hours later I tried to start the raspberry - I managed it running only on the second time. Then a I rebooted and got only red light on and the green one was very dim. Following advices on various forums I
a) replaced power supply
b) re-flashed the OS image
c) checked the card in PC (looks ok - all the files are accesible)
d) waited several more hours
Nothing has help (although once the green light flashed shortly). I wonder I some has the same experience and what might help to solve the issue (I am from the Czech Rep so I would like to double check before sending it back to UK).
Thx, Macky
PS: I overvolted the raspi to 900 MHz using raspi-config. But as I said the device worked for 5 months without any problems...
