Either your computer's memory was removed or something is interfering with the system checkup.
#MACBOOK PRO 3 BEEPS WITHOUT OPENING UP MAC#
If you hear this pattern of beeping, it means that the Mac could not find any RAM installed. When you start your Mac, it will automatically run system diagnostics. Here’s a short list of what each beeping pattern means: Do you think that may cause the issue? What should I do next to identify the problem or better: solve it? While your problem may indicate a RAM issue, it may not necessarily be the memory sticks.Sometimes you'll turn your Mac on and it'll start beeping in a variety of patterns. What may be the cause of this problem? Is it possible that the RAM is damaged (without memtest reporting an error?) or simply loose somehow? In some forum I read it may be the logic board.
System.log and kernel.log do not contain any error messages (at least none relating to a kernel panic). It may be worth noting that every time the problem occurred I was playing some flash video. Also I'm puzzled since it did not always hang with three beeps (I got a “regular“ kernel panic most recently, with that black PNG in the middle of the screen, telling me to reboot). However most sources agree on the fact that system diagnostics are only run at startup - so this should not happen in other modes of operation. I googled the issue and found out that signal a RAM issue. Turn off, turn on, everything normal again. The grey start up screen is interspersed with terminal messages repeatedly sagin '8debugger called: ', three loud beeps. This happend three or four times, every time it boots up as if nothing happened. After a while the screen freezes and I hear three loud beaps (they repeat). I thought some process must have stopped the mac from switching to stand by and kept the processor busy, so no big deal. The MacBook was in standby (as always) but very hot (not usual).
I noted the first strange thing a few days ago. My Feb-2011 MacBook Pro hangs with three beeps.

Apple Footer It is in mint condition and I don't know why it's doing this. I have never dropped it, or damaged it in any way. I take REALLY good care of this MacBook Pro and let no body touch it. It ran flawlessly for a couple of hours, but then the crash came again! I thought it was an overheating problem, but I got smcFanControl and boosted the fan, but the problem still occurred. I replaced the RAM and the laptop seemed to work perfectly.
I decided to buy new RAM, so I got 2 4GB modules. However, when I connected both of the RAM sticks, it crashed in 5 minutes again. I took out one RAM stick and placed it in each slot, the MacBook Pro was running fine while playing a 2 hour movie. I searched online and people said it was a RAM issue. I turned it on again, and it froze and beeped after 5 minutes. I thought it would fix itself, but it got VERY hot, so I shut it down to prevent any interior melting or overheating. When this happened, my MacBook Pro started to get hotter and hotter. It kept going until I had to forcefully shut it down by the power button. I was taking notes at school and suddenly the laptop froze and gave 3 loud beeps, then a pause, and 3 loud beeps again. It has been working perfectly until 1 week ago. I bought my MacBook Pro in August of 2011.
