So about a month ago I had my hard drive replaced, bc comp. guy said it had ran out. The problem that had led to that replacement was due to my computer refusing to load. It started with a week of my computer kicking me off internet explorer after every 30 mins of being on it. Then one day after all that it decided to not upload anymore. Whenever I turned the computer on I would get first black screen that asked to select operating systems, after I did it told me there was a hardware/software problem. It told me to restart using safe mode and a million other options, none worked. So comp guy replaced harddrive and that fixed problem. Since then the comp was running like new, until i tried plugging my ipod and camera onto comp. As soon i pluged in the ipod or computer to my computer it restarts the comp and refuses to load up as long as either the ipod or camera are connected. It takes me back to the problem I had before harddrive was replaced, doesn't let my comp load to desktop and stays on those first 2 black screens. As soon as i unplug the items , it goes back to normal and comp functions just fine. What can possibly be going on? Ive tried pluging the items through back and front ports and it does the same thing. Help please!
