I have movies stored on internal hard drives in my computer. I have my computer connected to my Marantz A/V using a HDMI cable. I also have my flat panel TV connect via ARC to the A/V. This is so I can play my movies thru the A/V to the TV. While using my PC for anything else, general use, like paying bills or surfing Cmputer Haven or Facebook for example my computer triggers my A/V to turn on. After a 30 sec to a minute the A/V turns off. The TV never turns on which is good. This may happen 2, 3, or 4 times over a couple hours. I have searched thru the settings on both the A/V and my computer but can't put a finger on what is doing this. I do believe this is happening from the PC side not the A/V side. Does anyone else have a similar setup with the same issue? Thanks in advance for your help.

Not the same setup as I use 2 HDTVs. One is connected via HDMI and the other through a DVI to HDMI cable that is modified to also carry audio. Cable, DVD Player, cable and VCR are also connected to the computer through a TV/FM Haupauge tuner. Audio is patched to my Yamaha sound system via Optical Digital Audio. Cable is also directly connected to both TVs. Gives a lot of options.

By chance is there a DVD in the DVD burner on the computer?

Does your keyboard have media keys that you may hit by accident?

As a first step I'd reset all involved units by totally removing power for a short time.
