My iMac wont turn on
I have a Imac 21.5 mid 2010. After i changed the HD for SSD It does not turn on. I put back the original HD, but the problem persisted. The 3 lights at logic board turn on, coolers turn on, i can hear a click in HD. However, the imac still present a black screen. Any idea what could be?
My imac is core i3.
Weel, i checked all cables and all were connected. The ligths 1, 2 and 3 still turn on. I rear a little sound like a beep. But the computer does not boot. The HD gives a little snap but i think its not running.
