Try clearing/formatting Cache partition from recovery and than flash a factory image. If it doesn't work, flash a custom recovery and than format the Cache partition and try rebooting your Nexus 7.
You can flash a new recovery image with fastboot. The command is: fastboot flash recovery recovery.img where 'recovery.img' is the name of the image. If you enter fasboot on the command line with no options or parameters you will see the usage, which is: fastboot flash [partition] [filename]
