I have an RPi2 that was working fine until I tried to boot it an hour ago. The red light is steady and the green light continually flashes, but nothing appears on my monitor.
I use an HDMI-to-VGA converter with my Pi, and when I was putting it away this morning I accidentally dropped it ~3 feet onto the floor. I wouldn't think that this should make it stop working, and I'm not able to test whether this is indeed the problem because I don't have any HDMI displays available.
I don't think the SD card is the problem, since Windows 10 can read it OK. Any idea what might be causing the problem?
EDIT: The RPi doesn't show in the list of devices connected to my home network even when I connect it to Ethernet. So maybe the display adapter isn't the problem and I should try reformatting the SD card? I had to put tape on the SD card holder because the spring inside seems to be broken, but it was still working until now and I'm not seeing 4 flashes so I assume that it's not the problem either.
