So, I figured I'd have to take off the bottom and try switching the RAM, then try using only one then the other to see if the RAM was indeed the issue, but I figured I'd come on here to see if anyone has experienced anything like this and/or can tell me how I should go about fixing it. Booting up the hard drive into Mac also caused a shutdown in the same amount of time. It then started to beep again, but when I let it sit for another few hours, it would turn on, still dimly lit, and shut down in 15-20 minutes no matter what I was doing. Nevertheless, it shut down about 15-20 minutes in, right when I tried loading my save again. Actually, I guess the dimmer screen was the only clue. The two closest options were 'No Ram Detected' and 'Ram failed integrity check' which makes sense if my game overloaded my used ram somehow and/or caused electrical problems.Īfter leaving it overnight, it decided to turn on, although it was slightly dimmer and I could tell something was amiss right away. This was not an option on the Mac help charts, the closest ones were '5 beeps then stop' and '3 beeps with 5 second intervals then stop', but there was no option for continuous beeping, at least that I could see.

Last week, however, after installing almost 200 mods for the game Fallout New Vegas, I started up the game, loaded my last save, and right when the game started the Macbook shut down and started beeping, 5 second intervals, continuously. After replacing the hard drive once, its only issue was the heating while playing games on windows for which I used ice packs which may or may not have gotten water into the laptop and caused the latest issue, but I've been keeping it cool that way for over two years without any problems. It's rather old and worn at this point and has gone through several phases of problems during which it would not start and would overheat easily. My Macbook Pro (exact specs here) on which I run windows 7 via bootcamp, recently has run into an issue.
