Spiking Physical Memory

First off I would like to know how many of you have encountered this issue before. And second any ideas on how to correct it.

Here goes the explanation of the problem. While working in A-Cad 2010 things get slow then the screen turns white & Or transparent gray. If you open up the Task Manager. The Physical Memory is spiking in a reparative pattern; climbing if you switch the priority to high. Until the spiking stops work is very slow to impossible. On a few occasions I have let it sit for 45+ min and it worked it’s self out. I have tried setting the priority high and low I have also tried changing the affinity with no luck.

I thought the 3 of 5 of use in my company are experiencing this issue. And during a Lean BIM seminar I attended last week an Cad operator from a different company asked if anyone else had ever ran into the same issue above and low and behold about half of the group have experienced the same issue.

Please give use any suggestions you may have.

Thanks in advance for your input.

Wow, this is a first. 50%50% on the poll and no ideas on how to keep the issue from happening.
