I'm not a whole lot different here with PC Specs and do not see this happening.
I'll agree that the RAM leak spoken of about CAD has merit and I will, from time to time, shut down and restart at lunch.
What I have found with this current system similar to the OP's is using Dynamic Blocks has hugely increased the drawing size and therefore slowed my drawing down.
Not to the point of freezing but it is noticeable.
So in conclusion I'll support the low end PC theory in general but do believe there is something else going on.
Question: Will more ram help or is it pointless to do that with this grade of computer?
So far, 2 days without freezing. Used it quite a bit yesterday. A couple of times it looked like it was going to stop. It froze for 4-5 seconds, then resumed what I was doing.
I have been doing this:
1. Purging the "old" blocks already in the drawing & saving.
2. I have turned off the Hardware Acceleration feature.
3. Turned off windows automatic updates.
4. I disabled the External Refererences (Xref)
I don't really know if any of this really helps. Seems to have helped some.
With the XP system you will not be able to use much more RAM. You could install two 2 Meg moduels but you would still only be able to use 3 Megs.
Reads as though you have done the things that you need to do.
Any word on the Scale Lists (SCALELISTEDIT) or Layer Filters when you open the Layer (LA) dialog?
Any word on the Scale Lists (SCALELISTEDIT)
Yes, They are all just the default settings.
Question: Should I remove the scales that I never use?
Layer Filters when you open the Layer (LA) dialog?
I don't have any layer filters set up.
Scales - Only remove them if you want to. The problem came from several hundred being created in previous versions that in no way could be likened to anything you were using. The nomenclature was strange as well.
As for the Layer Filters - Very few users if any used these extensively either. For a version or two of CAD Layer Filters were created in the program randomly and ran to excess causing problems. I only ask these two questions to make you aware and to make sure these were not your issue.
