i'm not sure how interpret of this, last time tried looking fix problem suggested symptoms of hardware problem- overheating. i've felt heatsink on cpu while it's lugging, , it's cool touch.

please?

**edit**
computer has amd athalon 64 x2 dual core 3800+ 946mb of ram, , i'm using ubuntu 8.04... in case helps

according this, compiz using 72% of ram when system gets slow. that's major memory leak right there - it's causing system swap disk, making computer slow.

try turning off of compiz plugins in "compizconfig settings manager" (assuming have turned them on in program) , see if fixes problem. of plugins "unsupported" package may causing occur.

switching default gnome window manager solve problem:

code:
metacity --replace
(or switch visual effects "none").

edit: noticed you're using 8.04 - "compizconfig settings manager" might named "advanced desktop effects" under preferences menu.
