BSOD - on my new gaming PC.

Hello guys!

I just built my new gaming PC about 5 days ago, the BSOD started on a game called audio surf, i looked on google to see how to fix it, and people suggesting turning off the sound effects the game offers so I did, and it worked.

But BSOD has recently been happening at random times. Sometimes watching youtube videos, after I quit a game (after ive been playing for 4 hours) And recently in the Civ 5 demo, gives me the BSOD every 5 minutes into the game. Its pretty random...I OC my cpu but the temps are perfect, 30 c to 40c.
