Q: 3 beeps interval - what to do?
Hello,
Yesterday I was checking my mail when suddenly my screen turned to different colors in a certain pattern and a noise was constantly beeping 3 times per interval. I switched off my MBP and everything just worked fine.
I've searched for it because I thought it was something with my HD but there were no faults on it. I thought it was a virus or something but I didn't have any infections on my MBP. I searched the internet and I found that it was a sort of test that Mac does before starting up.
3 beeps: No good banks
What does that mean? I found also something about my graphics card. But I don't think there's a problem with my graphics card...
What do I have to do?
Any response may be helpful
Thanks in advance

P.S. I installed 8GB RAM instead of the 4GB that was in the MB when I bought it. It is the first time in 2 weeks that it gives that 3 beeps interval.
If I have Apple Care Plan, does it expires if I put more RAM in my Mac or does it have no effect on the Apple Care Plan?
MacBook Pro, OS X Mountain Lion (10.8.2), 15" 2.0Ghz i7 8GB RAM
