I dropped my computer, it made the 3-beep "RAM is screwed" noises, but it seems to be working fine now. What should I do?

Question

I'm bad at computers so be patient with me ... I dropped my 2.5 year old MacBook Pro from about waist height onto a concrete floor (I know!). Worst feeling in the world, especially after I had the hard drive replaced a couple weeks ago. Now the case has a little dent on the corner but no other visible damage. After I dropped it it started doing the "beep beep beep -- pause -- beep beep beep" noise, which after some googling I see is to do with something wrong with the RAM. I powered off and restarted it, and after the restart it seems to have nothing wrong with it; turned on fine, screen is fine, no error messages, no slower than usual. I checked the memory stuff in System Report and it says both sticks are OK. I also ran the "verify disk" thing to check my hard drive and got no errors.
Can somebody tell me what the odds are of this computer surviving for the next couple months? I would take it to an Apple store, but this is complicated by me being in Rwanda, which means getting my computer fixed or even looked at is highly unlikely. I've got a friend coming to visit in a week and she could just buy me a new computer and bring it over, but I really, really don't want to have to buy a new one if this one's going to work. On the other hand, I'm terrified that this one is going to up and die on me before I get back to the US in August. Still, it seems to be working OK -- but is it going to die out of nowhere? Would you buy a new computer, if it were you? Does anybody have any ideas about what might happen to this one over the next few weeks? Thanks!

venicespent,
Boot into your Mavericks Recovery partition by hold down the command and R keys whilst booting. You'll see a screen that looks like this:
Click on the Disk Utility item to open Disk Utility. You should see your boot drive (usually named "Macintosh HD" unless you've changed it) in the column on the left of the screen. Select your boot partition and click on the "Verify" button. Let your Mac do it's thing - if you get green text telling you that everything seems to be OK, then your disk should not be damaged. If, however, you get red text telling you that the disk needs to be repaired, click on the "Repair" button. If the disk can be repaired, you should be good to go. If the disk cannot be repaired then the drive is damaged.
But before you do anything, make certain that you have backups!!!
