Ram problem?

[Kreteno]

So a few weeks ago my computer stopped working while i was blowing the dust out with an air gun.
I get 3 long beeps on startup and i've tried everything... removing the graphic card, removing ram, trying other ram everything!

The board is Intel® Desktop Board DG33FB

Please help me, I have no idea what to do!
If you need any more information just tell me.


PS. I don't know much about computers.

I could of knocked something loose on the motherboard using the air gun. Should really use air girls. Even compressed air I'm skeptical about using.
