Hello , the other week I knocked my already temperamental dr bott lead that powers my Sony Bravia display , the screen went down , I had to do a hard shutdown several times as the screen wouldn't power back up , it eventually powered back up but when loading the question mark folder was flashing , after over a week at trying all different start up modes & disk repairs & reformatting's I finally did the apple hard ware test & this error code showed ??? My mac still boots up but is very slow & still once loaded operates not the way it should do , can somebody please help me solve this matter , thank you
