My MacBook is experiencing Random Hard Freezes when unattended

Appreciate any guidance on solving this mystery. I have been experiencing random hard freezes on my Macbook for a few weeks now. For what it's worth, it has never happened while I was actively using the machine, but if I leave it idle and step out of the room, I'll return to a frozen state, i.e. mouse doesn't move, keyboard unresponsive. It seems truly frozen because if I close the lid to put it to sleep in this state, it never goes to sleep (well, not within a reasonable span of time, I haven't left it in that state). I have to hard reset by holding down the power button.

I've run Apple's extended hardware test and it finds no issues. I've run another memory test that also shows no problems, and I've even tried swapping out my Macbook's original memory and experienced the same issue. SMART utility said my hard drive had errors and was failing so I hoped it was that, but I used super duper to copy everything over to a new drive and the issue persists.

I've resisted a totally clean install because I hate the idea of having to get all my software installed again, etc, but I'm fast coming to trying that if there's a chance it will resolve this, i.e. that it's not a hardware issue.

The only crash report I found did not coincide with a freeze but I removed the software (Logitech Control Center) that crashed to no avail. If there are any other details I can provide that would help narrow this down, please let me know!

I've saved the console log from around the latest crash/freeze, but it's too big to paste here in comments. If there is anything specifically to look for, I can paste just those portions? Nothing leaps out at me and there is no crash report other than one mentioned above.

Clean it - might be overheating - on a machine that age the thermal paste could be dried out. Run AHT 3x in a row... if it's overheating one run alone wont uncover that.

If this answer was helpful please remember to mark it accepted.''

I suppose anything is possible, but if it were overheating, I'd think running Adobe Lightroom, Photoshop and other open apps all at the same time would trigger it not simply sitting still on my desk? Are there any telltale messages to check for in console that would indicate it overheated?

The logic board was replaced (under AppleCare) in late 2010, and it was supposedly checked over thoroughly while they put in a new screen (also AppleCare) at the end of 2011. I more than got my money's worth out of Applecare this go-round... So some of the components are not so old as one might think.

I will try running AHT repeatedly but not tonight. That was around 1.5 hours just to run through once.

Thanks for the advice!
