Computer turns on randomly?

My main PC often turns on randomly and I can't figure out why! Sometimes it's completely random (for instance it has turned on in the middle of the night a couple of times.) At other times there's a pattern. Sometimes it will turn back on about 5 minutes or so after I turn it off. Last night I turned it off and it turned back on in about 5 seconds, and kept doing that when I turned it off till I switched the PSU off.

I have no idea what might be the issue! I looked to see if my power/ACPI settings may be causing the problem but I saw nothing that was set wrong. The PC has a Ultra X-Finity PSU as well as a fairly cheap ECS (Socket 775 w/Pentium D) motherboard. I am thinking that one of these components may be the culprit because, well, they're cheap! (and of course they're probably the most likely to have the chance to cause the problem) I've had these components for about 3 months (since QuakeCon) and they worked fine for a month or two then these problems started to appear.

Any ideas as to what might be going on would be appreciated - thanks!
 
The switch on the case may be going bad or sticking. I had one where the button would pop back out after pressing but the switch was still making contact.

Could be a key stuck on the keyboard and the BIOS set to "Wake-On-Keyboard". Had any sticky fingers around the computer lately??

The power switch idea sounds like it may have some merit so I will look into it. I had recently bought a new case for the system anyway. I seriously doubt it is wake on LAN/keyboard because I looked at all of the power settings (that I know of) in BIOS and I saw nothing strange.
