Weird PS3 and Onkyo 805 bug

[Firestreak]

I just downloaded a couple of demos, and they will repeatedly shut my receiver off when on, like every few seconds. only have enough time to turn the receiver back on, hit the PS button and quit the game.

Not sure what the problem is, Should I just call up Onkyo, cause it's like less than a month old receiver, and my PS3 is a replacement that's like 2 weeks old as well.
