I havent had time to test it any further. I can tell that after disabling Onboard CIR Power On in the BIOS the system has not booted itself anymore. So something is triggering the boot through the CIR.
I did notice a spark when I plugged in the power plug. If the ungrounded case has anything to do with the system booting itself, I really dont know.
I do not own a plasma TV but I have a LCD TV (Sony 37W5500) but I just read that LCD also emits IR. Other stuff I own and which is being used or standing near the ION-330:
- Harmony One universal remote
- Wii (currently standing next to the ION-330)
- Humax i5050c digital TV tuner
- A/V receiver
My first try is to move the system out my A/V cabinet and place it at some distance from all the rest and the enable Onboard CIR Power On in the BIOS again. See what happens.

I had this problem when I first got my 330HT however it stopped once I disabled Wake on Lan. Most likely caused by noise on the Ethernet cable since it travelled up behind the TV.
One thing, the odds of a TV generating a 36KHz Modulated ir signal with the correct RC6 ir code to tell the receiver to turn on is all most impossible.
More likely they have not used adequate decoupling capacitors and inadequate ground planes for the ir receiver chip. Therefore noise either from connections to the TV or EMF is causing the device to power on.
A TV will generate more noise and EMF when turned on however even when powered of the PSU will generate some noise and EMF.

Look at the left side on the front are some holes. The holes look like air vents. You can look through the holes and you will see the IR diode.

You may want update your bios to 1.10 and see if that helps.

This being stray IR signals seems very very likely. I find my plasma emits LOTS of this noise, visible by the fact that both my IR-pyramid and my MCE IR-receiver blinks, or is lit all the time. Actually, I also have a CFL in the ceiling, and this also seems to emit IR noise! Luckily I do not (can not) use wake-by-usb with my current hardware, and the noise seems to not have any detrimental effect yet.

Now that I have installed the Linux drivers for the internal IR receiver and have moved the box a little away from the TV the issue hardly ever occurs.
I dont use the suspend mode from XBMC Live but use my remote to boot from power down and that is working fine now.

I recently bought an Asrock 330 incl remote. I see the following:
1. Seemingly random boot of the computer, with nothing but power cable attached, no remotes being pressed, nearby Samsung LCD TV turned off. This also happens during the night, which I find is even more puzzling. I have installed nothing onto the machine, so OS-dependence seems impossible.
2. Sometimes sparks when plugging the power cable into the back of the computer.
Update: After disabling the onboard CIR power on in the bios, my system no longer starts by itself.

Hi, i also have problem with auto boot on my asrock.
Did someone report this problem to Asrock, can this be fixed?
