Well, what IS your hardware?
Need DETAILS of computer brand/model or motherboard brand/model if self built... including installed ram
Brand/model of graphics adapter (ATI or nVidia or ???) and driver version... and do NOT count on Windows update!!!
nVidia Driver Updates http://www.nvidia.com/Download/index.aspx?lang=en-us
ATI Driver Autodetect http://support.amd.com/en-us/download/auto-detect-tool
Exactly what are you editing
Since you write "computer down" you MAY have a hardware problem, so read http://forums.adobe.com/thread/772169
Thank you for your feedback John.
I have solved the problem, after I realized, that can be my hardware! I have solved it - with my wife´s hoover. :-)
I use all-in-one from Acer with i5 four-kernel processor. Since 2 years. It was really a hardware problem - obviously thru the dust became the processor too hot and switched off as an instinct of self-preservation. After 5 minutes cleaning - it runs without one interruption.
But I will follow also your recommendation according driver check and update.
Thank you once more and good bye from Prague.
Heat build-up is one of the prime causes of computer shutdowns, and cleaning the heatsinks, fans and airflow channels can go a very long way to allowing one's computer to function well under load.
Thank you for reporting your cure.
Good luck and happy editing,
