When i find the RAM wich worked, showed up at System Profiles, i did not get any hold ups, balloons or crashes at all. I was running it for hours last night without problem. I'll see if i can find 8 pcs of matching 1GB modules (like it would really matter having 4GB vs. 8GB). I'll try up the ASD 2.5.8 when have time. Now it's running 10.5.8 quite nicely.

For sure, the dust needs to be cleaned up from the processor unit, not sure if go that far to take parts whole machine however. Not my favorite machine to work with :O
