Unexpectedly Quitting at Every command

[philip_watson@adobeforums.com]

Im trying to use Photoshop CS on my G5,10.3.3, 2.5gb of RAM, but of late, everytime i try to do something, anything, especially transforming, it just quits right in the middle of an operation. I would like to know what can be the possible cause for this and how do I stop it. a 30 minute project is now going on an hr and a half because of this nonsense. Any and all help is appreciated. Thanks

How much RAM is allocated to photoshop??

how big is your scratch disk??

is it on the same drive as the system??

What is the ppi of the file??

how big is the file??

To elaborate on Buko's comments:

Run "Repair Permissions";
Allocate not more than 65% RAM to Photoshop;
Check all internal connections (including card-seating);
Suspect bad RAM……
