I've been experiencing random crashes on an HP Pavilion laptop which has run the BOINC client for some time. Stopping the client seems to prevent crashes. I've noticed that BOINC's CPU use runs in rapid cycles from 20% up to 100% and back which seem to lock up the processor from time to time.
Here's a bit more detail on the processor use -  - the nice diamond shockwave shapes mid run on the top CPU graph are where I started and then stopped BOINC. The processor bumbles along happily both before and afterward. Here's more information on the OS -  I don't want to stop running the BOINC client, but it's now interfering with my work - any observations or suggestions for how I can calm it down? Any help gratefully appreciated. Gaz |

My first suggestion is to clean the inside with compressed air. If it is clogged with dust, the system will get hot quick and may shut down to prevent damage. You should try monitoring heat and let us know what temps it gets to. Also, let us know laptop model, OS version, processor, BOINC version, How many cpu cores/threads you set BOINC to use, and what sciences you are running on the laptop. Also if CEP2 is being ran, I have seen laptops BSOD while running even just one of them on cheap hard drives (mostly Hitachi) that test as functioning fine. Let us also know if the laptop is crunching projects outside of WCG and if any other project is running on the GPU as well.

One thing I would strongly suggest, is to install some sort of temperature/throttling software (TThrottle is one I, and many others use - details of it are in the FAQ's). With this, you can set BOINC to run full tilt and let the TThrottle software control the throttling of how fast the BOINC software runs depending upon the temperature ceiling you set it to run at. This will also smooth out the 'peaks and troughs' in the rather crude manner BOINC attempts to (say), run at 60% (3 seconds on, 2 seconds off).
