the last two days my machine has suffered a crash with similar symptoms.
First, the display goes blank. I can see some disk activity. This continues for maybe 20-30 seconds and then the machine shuts down. Yesterday, I had to restart the machine twice b/c the first attempt also resulted in a shutdown during the boot process.
I thought that perhaps it was an overheating issue, but I'm not convinced of that as today there was nothing obstructing the exhaust vents (though they were a bit dusty).
I'm runing windows 7 pro, 64 bit. Have an NVidia card, but I don't know about the details. Where would I find them?
Thanks in advance.

If it is a W510, graphics are probably 1GB NVIDIA® Quadro® FX880M. It is hard to diagnose from a thousand miles away, but my first guess is overheating. I suggest installing TPFancontrol (free) and monitor temperatures.

Installed it. Looks like the CPU is running in the mid 60's (C) most of the time. What would be the high end of normal for this CPU?
Thanks for the quick response, BTW.

I wouldn't think that 60C would get you into thermal protection territory, but you may wish to pull the keyboard and give the machine a good dust blow-out. Be sure to hold the fan blades stationary while using compressed air and blow from the inside out through the exhaust vents.
Edit: In addition, pulling the keyboard bezel looks like it would give even better access to the fan / exhaust vent areas for a good de-dusting.
For reference, you can pick up your HMM here: http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-74250
There are good step-by-step instructions included.

That's for the diagram. I removed teh keyboard and blew out the inside of the laptop with some canned air and I havent had any issues since. working temps have been in the low 60's since the cleaning.
