Recently, my iMac has been acting up by randomly crashing and then beeping 3 times loudly 3 times when I try to start up the computer. I found out that 3 beeps means its a memory problem and I am scheduled to have Apple fix it. However, I really want to back up my files (especially iPhoto) before I take it in to them, since they can’t guarantee that the data will be there when they are done working on it. The problem is, the computer won’t stay on long enough to back up my files. Sometimes it will start up for a few minutes, but after that it will just crash again and beep 3 times. Please help me find a way to backup my files before I take it into Apple for fixing.
