what do these beeps mean?

[KoolAidMan]

I opened my case to try and dust it off a little, all i did was blow on the fans really, and now it wont turn on. It doesnt show anything on the screen at all, and it makes 2 alternating beeps. It is award bios, and it doesnt say anything about this beep code, at least not that i could find. Could blowing on it have done something to my video card or ram somehow? any ideas on what it could be?

Sounds like a ram problem according to this Award beep guide,

Beep Code Description
1 long, 2 short Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information
Any other beep(s) RAM problem.
