Sudden shut-downs and random reboots
I've been digging around for a couple weeks now for information on what may be happening to my MBP. I've tried numerous solutions, but don't seem to be able to get the computer to STAY ON. Here's my story:
A couple weeks ago, my room mate was using the computer. She closed it to put it to sleep, and left it on my bed. When I went to turn it on, the screen was completely black and the indicator light on the open button was a steady grey. The computer was so hot it was painful to the touch. I unplugged it, hard powered it off, and let it sit, thinking it was an overheating issue.
Since then, the **** thing won't stay on. Initially, it would intermittently just shut off. When that happened, sometimes I could boot it back up, and other times it would sound like something was whirring in the background, but the screen stayed black and the indicator light stayed solid grey. I installed SMCFan and istat to monitor/control the temp and fans.
I noticed somewhere along the way that there seemed to be some connection between episodes of shutting down and the power cord (as in, if it was jostled, the computer shut off)(I should note that my battery is at about 15% health with a full charge). Then, that power cord died (no green/amber indicator light and no connection detected). So I bought a new cable, and set about trying to fix the problem again.
Next phase, it seemed that if I moved the computer, it shut down. So I did some of the recommended fixes. I deleted the power management plist, I changed the settings to never put the computer or the display to sleep, and I turned off the quick-motion sensor that stops the hard drive. I also reset the SMC settings.
This seemed to improve the situation a little bit, insofar as now instead of getting a shut down, I am now getting complete reboots that only *sometimes* lead to the blank screen and steady grey indicator light. This does happen more frequently if I move the computer, but it can also happen if I simply leave it to run. In fact, if I send the computer into sleep-mode, and close the lid, I'm practically guaranteed a reboot.
So, then I reset the PRAM and did the hard-reboot (ctrl+opt+power) and reset the PRAM again. I am currently running Rember to test the RAM, but I'm not sure what to look out for when it finishes, or what I should do about it.
On the last reboot, it actually gave me an error report (that's the first time it's caught it). Here's the text:

A weird thing is that there's this TINY little squeak sometimes when the computer shuts down. Like a mouse whispering or something. And when that happens at shut down, it must sit if I am going to boot it up again, or else it shows the totally black screen and grey indicator light AND makes the squeak again.
Yet ANOTHER weird thing is that the last two times I've turned it on, the indicator light stays completely off.
HEre's some more info from about:
Processor: 2 GHz Intel Core Duo
Memory: 2GB 667 MHz DDR2 SDRAM
Clues, anyone? I'm too poor to buy a new comp, and all of my photos are on this laptop. I'm typing this from my desktop, and in the middle of running Rember, the laptop died and squeaked. This is so frustrating!~!! Help!!
