Switch and AP NOT WORKING

[Richards15]

The switch and access point were working completely fine, then both ap went completely down. This is the second time that this happen, lasti time I disconneted the power cable and connected again and everything started to work fine, this time i did this process over 5 times with no luck, the ap got no power and it looks like the switch its stock trying to boot, it got 2 lights on (syst and power) and when  I tried to reset nothing happen.

I tried to do some tutorials that i was able to find here but nothing its working....
