I put in a new hard drive, upgraded the ram and new battery
I went to go power it up and all I got was a beeping noise like “beep,beep,beep,…………..beep,beep,beep………….” now nothing works. No power indicator, no noise, nothing on the screen. I put in the new hard drive because I was getting a folder with a ?Mark in it. Any suggestions? Could it be the logic board?
