PS3 and reciever problem, please HELP!

[soright903]

Hey guy, heres my setup and problem.


Setup:

Onkyo-tx-804 receiver (supports HDMI 1.3)
xbox 360 and wii, hooked up via component cable
cablebox and ps3 is hooked up via HDMI

Problem:

Ok when watching blu ray movies or playing PS3 games my receiver shuts off randomly. About every 10 min or so. It happens more often when watching movies. Also when on a pause screen during a game and on the main menu that loads up when you power up the PS3, the screen "twitches." (even the ps store) By that I mean the text goes left and right really fast making it hard to read, almost like the text is always moving. (i hope that made sense)
This problem ONLY happens when using my PS3. So I dont know if its my ps3 thats faulty or my receiver. My cable box is also hooked up through HDMI and never have a problem. Ive had my PS3 since January and only encountered problems until a few weeks ago. Its only gotten worse.


Does anyone know if there are some settings on the ps3 that might help me adjust this? I dont know what to do, anyone have any ideas?
