Red lights help?

Hey guys. I turned on my Xbox 360 without the sound on and left it on intending to get on later.(I use my 360 and PC on the same monitor.) I proceeded to play Starcraft 2 on my monitor for about 20 minutes or so when I looked up and see the three red lights of death flashing along with the green power button. I was shocked so I turned off the console and restarted it. After I did...everything was fine? It booted and Xbox Live started up. WTF? Does it normally do that? What should I do? Thanks.

I've no idea but Microsoft's support page for three red lights in the RROD might help.

" sounds like the xbox is on its way out.  It may have been asking for help.  Open it up and switch out the video card.  That should help "

xboxes tend to dance around death in this way before they make the final waltz out the door. Brace yourself for the worst, buddy.
