Help CPU automatically restarts itself....

Eventually, when I get my cable card, I do plan to keep my htpc on all the time, but for right now, I would like to turn it off. Within the last hour I realized that everytime I turn my cpu off, it powers right back up again in about 8 seconds. Prior to this, I downloard plex off of Assassin Guides and I physically change the location of my CPU in my home theatre setup. Prior to coming to AVS, I did do a quick google search on this and there was a mention that perhaps it turns on when it senses a LAN connection and I would have to configure this in the BIOS. Since this never happened before, I poo pooed this explanation, but sure enough when I unplugged my LAN, and powered off the system, it never came back on. So is this an hardware issue or software. Did I destroy something in the CPU when I moved it, I have not been in the bios since so I can see how I configured the CPU to power up when I a LAN is discovered.


I look forward to your tips and advice.

This may very well be the case, but how would this happen all by itself. I have had this CPU for about a month and this problem only happened after I downloaded plex and I moved my CPU. Can something change the BIOS, without going in the bios.
