How can I figure out what's causing my PS3 to start, and stop it?

Yesterday, my power randomly went out while my PS3 was on. It was just sitting their idle on the main screen, wasn't in a game. When I turned it back on, it went through all its hard drive checks, etc. I'm not sure if this is related, but this didn't start happening until immediately after the power outage.

Anyways, I can't seem to keep my PS3 turned off without actually removing the power from it by flipping the power switch on the back. Every time I turn off my PS3 either by [Users] > [Turn Off System] or the power button on the front, it will automatically start back up on its own a few seconds later.

Is there any way I can figure out why it's doing this or what's causing it, and how can I stop it?

I was able to solve this by resetting all the PS3 settings and all the controllers. It's not the greatest thing reconfiguring everything for your PS3, but at least it doesn't delete any game or save data.

Apparently the PS3 kept thinking it was receiving a signal when there was no signal being sent, like it was trapped in there constantly trying to connect something that wasn't there. After the power outage, I tried to start my PS3 via the controller but it didn't work. Then when I started the PS3 via the power button on the front (moments later), the controller turned itself off and I had to attempt to reconnect it again. Weird issues, all is good now though.
