Did you start up in Safe boot (hold shift key and power up) Cant do much will there so after it starts shut down, and is probably similar to your cache cleaer. Your might read
First read http://support.apple.com/kb/HT3805
Delete the user's (Apertures preferences) ~/Library/Preferences/com.apple.Aperture.plist
Delete the Aperture cache. The cache file to delete is located at ~/Library/Caches/com.apple.Aperture then reboot again.

1: Use command + S and power on the Mac to start in single user mode then type sbin/fsck/ -fy (after that is finished… type) reboot
There may be a simpler way but all the above covers a lot of variables with some overlapping fixes. Its like a tune-up for the car. Let us know if there are still issues after the basic steps from above are taken. Good luck
First of all, thanks for a reply!
I've done everything suggested plus deleted all caches/reinstalled Aperture/reinstalled Lion, again cleaned the system. Yesterday I edited about 15 pictures without any crash and thought that everything went OK, but… Today I imported 38 new photos and while browsing previews again got that familiar black screen with no chance to bring the machine to life. Once again POWER button and not a system report.
The only thing I noticed, that crashes occur when I use any sliders or change views fast. Aperture’s always been hungry for system resources. I suspect it simply does some heavy calculations and somehow hangs up the whole system. Yesterday I made small pauses 5-10 sec between adjustments and got no crashes. If I’m right about that it makes my wonder how PS CS 6 manages 25 files of 50 Mb each and the native app from Apple can’t work with RAW file of 15 Mb?!
That seems to be a “hidden invitation” from Apple to go for a new Mac Pro if I like to continue using Lion and new Aperture (mine is old, but I don’t see any reason to change it for so called “new machines” especially before I’ll get a new camera). My Mac Book Pro (2006), which is still on Snow Leopard, feels good with Aperture, slow, but not crashes.
My primary machine:
Model Name: Mac Pro
Model Identifier: MacPro1,1
Processor Name: Dual-Core Intel Xeon
Processor Speed: 2 GHz
Number of Processors: 2
Total Number of Cores: 4
L2 Cache (per Processor): 4 MB
Memory: 8 GB
Bus Speed: 1,33 GHz
MAC 1 - SYSTEM:
Capacity: 499,25 GB (499 248 103 424 bytes)
Available: 368,54 GB (368 542 355 456 bytes)
If you did all of these and you have 8gb Ram then I think I research for a Ram test utility. Drive Genius has one dont they? Or you could have a bad video card or logic board. But Im guessing at this point you need a higher level person and a Mac Genius
Drive Genius deals only with HDs.
I will try to replace my videocard with the original one and see what will happen.
About Mac Genius:) Apple doesn't like us in Russia, we don't even have a singe Apple Store for the whole country, so we are on our own. That's why I wrote here.
Anyway, thank you for your cooperation!
I changes the videocard for Radeon HD 5770 (it works with MacPro 1.1). For three days I’ve been heavy working on my photos in Aperture. I’ve got not a crash.
But my old Radeon X1900XT seems to be OK because before that change I performed a lot of graphic work in PS CS6, PSE 10, iPhoto, Acrobat X other graphic soft – not a crash. As soon as I opened Aperture, 5 minutes and my machine was down again.
It seems to me that Apple somehow made changes in the graphic engine of Aperture without paying attention to the optimization of its performance. Now it consumes all graphic resources and older machines are unable to handle Aperture.
Here is another unlucky one with a similar problem:
I am having exactly the same problem but I don't have Lion installed. I work on a Imac27 2.93Ghz Intel Core I7 with 8Go of Ram. Aperture 3.2.3.
No problem at all with any other software, including PS6 and FianlCut Pro. But Aperture cause that weird crash, black screen. Seems to happen when doing many operations of sliding adjustments a bit fast (but not sure it is related yet). Don't you think there is an OVER HEAT problem caused by Aperture and the screen goes black to protect itself of the graphic card or the cpu is shutting down due to overheat?
Thank you for any help!. I bought that Imac to do photo retouches, bought Aperture as well and now it is a nightmare.
Before starting this discussion I thought like you that it was a kind of over heating, fast adjustments, full screen mode and so on. But fans in my machine were silent, Aperture crashed after a couple of minutes of work and either in the full screen mode and in the browser window. Don’t waste your time repairing permissions and other maintenance stuff you see in this discussion, it didn’t help. I even reinstalled the system several times. The problem lies somewhere inside the software and the hardware. As you can see, I replaced my video card and since that time I haven’t had any crashes. In your case, iMac, that could be a little complicated but try to replace the video card by more powerful or at least by a new one.
Don't be upset! At least you have an Apple service and stores somewhere around, none of these here in Russia. I hope that my experience will help you to solve the problem! Aperture is getting hugry for system resources with any new upgrade, next time I will wait for a while before upgrading.
