I recieved a Raspberry Pi as a gift in April. About two months later, it stopped working. The screen displays the color splash, then scrolsl some code, then the "Hold Shift" screen and then starts over. The green LED will blink once, and then only the red LED will remain on. I have researched this problem many times and after testing numerous cables and power supplies and re-writing NOOBS to the SD card, I have given up. I have also made sure that there aren't any peripherals drawing too much power from it. If anyone has any ideas on what might be the problem or what I should do, that would be greatly appreciated.
p.s. I do not have a multimeter, so I can't measure the voltage or anything. It probably wouldn't make much of a difference, anyways, unfortunately.
