Perhaps you have installed some other codecs or codec paks on the system after premiere. So that would contribute to crashes.
No, I did not install anything.
Are your OS on 32-bit or 64-bit? CS5 only works on 64-bit OS. Or your PC might need more ram. Good luck.
I have a 64-bit syetm and 4 gigs of ram.
Hm-m, 4GB RAM on a Win7-64 is just about enough to run the OS, and really not THAT much more. Can you bump that up?
It might be possible to get a bit more for PrPro, if you do a good cleaning of the Startup & Services, that are not needed for an editing session. This ARTICLE gives some tips, and also points to some links for Win7-64 Tune Up (Black Viper's Web site).
Thanks ever so much for responding. The problem is that my laptop, which is also using Win 7 but with much less ram, experiences NONE of the symptoms that this stand-alone does. The same holds true for my other stand-alone, presumably the twin of this troublesome stand-alone, in my city place 130 miles away.
Jonathan, my computerman, who alas is away this week, theorizes that some Win 7 update may be the culprit, that or a chip may be damaged; since neither of the other two computers has experienced anything like this problem, I suspect it is a chip. The fact is that something SUDDENLY happened on this system. Earlier in May I created a complex 2 gig show on this system in a program called Proshow Producer, using video clips that I edited in Premiere and psds and jpegs that I created in PS, and I posted same as a 450-odd meg avi on Vimeo--all with no grief whatsoever. Then I began on a new show on this same stand-alone, but I hadn't gotten very far with it when suddenly everything began going bonkers: multiple crashes when trying to use Premiere, my wiping the whole Creative Suite out and reinstalling it 2 times, with assistance from Adobe tech support (very coldly and unsympathetically, I must say). I've had to take all of CS off again. I've left on only Photoshop, which works fine, and on the laptop I installed a trial version of Premiere, which works fine there. Yes, I tried installing a trial of Premiere on this stand-alone, and the system crashed yet again. As for Proshow Producer, as soon as I tried to load the first few slides of my new show, it crashed; I tried the same on my laptop--no problem.
Any suggestions that you or anyone else would care to make will be greatly appreciated.
