Who installed your SSD? Is this an Apple SSD? Run Apple Hardware Test on your system, Take a look at this link, http://support.apple.com/kb/PH11342

i installed the SSD, that doesn't seem to be the problem tho since i just booted it fine and disk utilities showed everything to be fine. I went to the bathroom just now and it shut itself off and is doing the power cycle thing again now...

Did you do hardware test, it sounds like it could be an over heating problem. Or a heat sensor is not connected.

holding D doesn't work, the computer just boots up for 2 seconds, you can hear the fans turn on, but shut itself off right after that and tries to boot up again.
I installed the SSD like 6months ago too, if there was something that i forgot to connect back it should had happened long time ago no?

You should take your iMac to the nearest Apple store for an evaluation.

ugh, thanks for trying to help. I guess that's the only choice, which is also something i've been trying to avoid... Lugging around a 27" in the mall is no fun at all.

turns out it was a faulty ram stick. I had 16gig, pulled out all slots and installed them back 1by1. Each time i would switch it on to reproduce the problem. Everything worked fine until the last stick.
So if anyone else have this problem in the future, check your memory sticks!
