I was trying to get rid of any files left from the adobe suite. I went into Finder and clicked applications. I set the search to system files and searched for "adobe". I pressed command+a and moved everything to trash. I emptied the trash. I shut my computer down. I thought It would be a good idea to reset pram. I pressed the power button and held the keys command+option+P+R. The mac started then turned back off. It started again but I got distracted and and kept the keys held down. It restarted a second time. When the progress bar finished, I selected my account and tried to login. I had to click it 3 times for it to let me type a password. When I entered my password, I got the spinning beachball for a few seconds. I was booted into OS X Yosemite. This is when I realized something was wrong. I looked at he top left corner, there was no apple. Just a blank space. I clicked it, a blank menu showed up. I couldn't do anything with any applications. I had to shut it down with the power button and reboot it. Same situation. I think I broke my computer. Is there a solution to this?
