Default Strange Power Failure

Ok so the last several weeks, perhaps once or twice a week, my computer won't turn on. Results cary, but sometimes I can press the power button multiple times and it will eventually turn on. Others, nothing happens until several minutes later it randomly boots up. A couple of times it has randomly turned off, once or twice a few seconds after I have turned it on.

Now when I say my computer is "off" there are no fans running or anything only the mobo LEDs. When it turns on the fans work and everything. Even with this problem, I would say my computer runs fine 90% of the time. I am using it right now, and have been using it in several intensive games without apparent temp probs.

I have reseated RAM, as well as the CMOS battery, replugged in several cords, attempted to boot it with the mobo power button when it's "acting up". The only thing I haven't managed to do is try and jump start the PSU when its messing up. Normally I only have a few mins before it will turn on by itself. However it's only acted up twice since someone mentioned jump starting it.

I am thinking of getting a tester from a friend, but I don't know how effective it will be especially since it is running fine now, and if it would work what it should be capable of. Any ideas?

Hmm, maybe there's something up with the power supply?

That's what I'm thinking. But with how sparsely a problem occurs (rarely will the computer not boot for an extended period of time), I have no idea how to troubleshoot it. I'm not sure what kinds of things a PSU tester does, or if it can catch a problem that's inconsistent.
