hi Great site love it

My 2011 Imac 27" 12.2 At Startup the bong sounds but the screen stays black two and a half minutes later the screen turns white and continues to operate normaly. This black screen 2.5minutes Happens at any start or reset. So installing is impossible.

The GPU seems to work fine otherwise Could This Be The Pram Battery ?
