I didn't find anything QUITE like this, so I'll post my issue:
When the power button is pressed (the controller won't turn it on- not sure if that's a symptom or other issue) it turns on.
It will then run for anywhere from 1 to 10 minutes.
During the time that it's on it's sluggish, especially right before it turns off- even the wave that's the ps3 background just twitches on the screen.
It then turns itself off. It beeps 3 times then shuts down.
----There is no yellow light at any time during this-----
-Troubleshooting to date-
Taken the disc out so it can power up with no disc.
Used canned air to make sure there were no dust issues (never been an issue before; and really wasn't on long enough to overheat)
Took out the harddrive (it's a third party upgrade) then put it back in to make sure it was properly seated. (note: the harddrive was changed almost a year ago, so it's probably not an issue.)
We DID have a brown-out & black-out that could have sent a surge into it, though both computers and the TV haven't been harmed. Also, it's worked each of the past 3 days since the storm with no issues until today. It seems like damage from the storm would have started immediately...
Thanks in advance for any advice!
