A shot in the dark perhaps, but I noticed that your machine has a DuoCore cpu and radeon graphics. On two of my similar machines (a ThinkPad T500 and a Dell Optiplex 755) I've given on up using radeon graphics alltogether. Especially the Dell machine kept on stopping completly. The ThinkPad has switchable graphics, ATi or Intel, and runs fine with the latter. On the Dell I gave up using my old ATi (RV610 chipset) a week ago and switched to the onboard Intel chip. I lost dual head but at least the machine is now rock stable. I cannot afford to buy more recent ATi (AMD) cards and test, but suspect radeondrm to be the culprit!? Erling
