CS4 seems to be crashing my PC

I recently upgraded to CS4 from CS2 on my Windows XP SP2 machine at home. The machine is pretty brawny: Intel Core 2 Quad CPU @ 2.4 ghz w/ 2 gb of RAM.

When using Adobe Camera Raw within CS4 to process Nikon NEF photos, the machine will suddenly crash completely. I mean, no error messages or anything. The machine literally just goes dead and shuts off, unexpectedly and I lose my .xmp files with color corrections. It reboots fine most of the time, but once it prompted to go into Safe Mode. I obliged and it seemed fine in Safe Mode, so I just rebooted normally. Seems to be when I have more than 50 NEFs open at once. Sometimes it happens when I’m in the middle of color correcting and sometimes it happens during the step when I select multiple NEFs and commence with Saving them as .jpgs.

Any advice on what to check out? I went into the Event viewer, but didn’t find anything suspect in there. Thanks in advance! -David

I ran windows update and upgraded to SP3. same issue as before.
I also cleared out a whole bunch of space on my C: drive so there are now approx 20 gb free on there.

what video card update are you referring to?

Not sure which card you have but they have made fixes in the Nvidia software. (I use Nvidia chipset cards)

This should be in the hardware section of the windows custom updates part..
or you should go to the card manufactures site and see if there are any updates for your card.

i do have an nvidia card. i went to their website, downloaded the updated driver and installed.

same problem with Adobe Camera Raw (under CS4) crashing my machine when it processes a lot of photos at once. CS2 was able to process hundreds of photos at a time on this machine before. i had to install CS4 to read the NEF files from the new Nikon D700 so I can’t downgrade back to CS2.

any suggestions would be much appreciated.
