Another thing you may want to check is, when you start up Ubuntu, open a terminal and type in 'top'. Also, Turn off/disable the screen saver AND allowing your machine to go to a blank screen on the monitor after x min...This will allow you to keep up the terminal that is showing top processes. I fear that you may have an issue with Xorg that is using up 100% of the processor. But you should see what was using up the most processor and memory usage at the time your machine stalls on you.

Thank you guys!
----------------------------------------I don't know what exactly helped but it works now! Firstly I tried to resize swap disk using Paragon (my mistake :)) and it killed Ubuntu and Win 7 lol Then I reinstalled Ubuntu with 4Gb swap. Now everything is ok, but I can't understand why - most of the time swap is not used, configuration is the same Mem: 4059736k total, 3344108k used, 715628k free, 253908k buffers Swap: 5482480k total, 1624k used, 5480856k free, 1485792k cached Once again thanks to all for help!

Darn*, I was wrong :(
----------------------------------------The problem persists. First time system freezes after 2 hours, now each 20-30 mins. I believe overheating? But in Win7 i see no problems... *edited to appropriate forum language - ErikaT

See today's post by piroque... maybe related, he found noapic acpi=off did give him most of his missing CPU time back, but it was described in searches that without it to be responsible for system freezes.

Well, acpi=off, no changes.
----------------------------------------In addition I've tested RAM using bootdisk memtest+ no errors. Today I'll try to measure temp of GPU, maybe it overheat all system. But it's strange - I installed last drivers from ATI and system should not utilize GPU (no heavy graphic application launched). It's only idea I have.

I got strange results:
----------------------------------------I tried to reinstall ATI drivers and by mistake i've downloaded drivers for different model (3870x2 instead of 4870x2). GPU temp is ok ~60C, but video acceleration don't works. Uptime was about 3 hours, but suddenly system restarts without any messages. Second uptime was ~20 min, and then another freeze. In the third time I worked on computer about 40 min, and then turned it of manually. So the story goes on :) I have no idea what is happening with Ubuntu, maybe ghosts? :D P.S. I appreciate any suggestions what different linux-like OS is stable and easy to install for BOINC

Maybe for starters uninstall all those drivers for the video card and revert to the set in the current distro repository. Mine are not the latest I know at 195.43 for NVidia, but they do the job.
----------------------------------------Of course, back in the old days, we started swapping parts with a system that was working to find the one that was causing the issue... one day it was the plug of the keyboard giving intermittent signals. PS: My Lucid Lynx distro fetched, by pure coincidence updated files for... you guessed it: acpi. PPS: somewhere someone brings up this story of the bulging capacitors... must have seen it a dozen times. Check the mobo.
