Laptop Keyboard/Movement Causing Crash?

Basically I suspect one of two hardware problem and an unidentified-yet software problem:

1: Overheating of the cpu due to limited air circulation. This is a very common problem with laptops because, as you noted already, air inlets are very small and the fan is tiny. The fact that we cannot measure temps directly doesn't make life simpler. Please try your best to clean the inlets and the fan. In some computer it's very easy to get to the fan and clean by removing a small cover at the back. Please check if this is the case in your computer. Do not try to open other covers unless you know exactly what you are doing.

2: Faulty hard disk. You mentioned in your first post that crashes occur if the computer is bumped. This should not happen if the bump is not too severe. We tested with BurnInTest and got no negativr results. This however is not enough for this case. Please identify in Everest the make of your HD, enter the manufacturer's site and download a diagnostic program. Run a complete test of the disk.

I don't see any problem with the processes. System Idle Process (not memory, like I wrote by mistake) looks normal. This paramater tells you how much cpu resources are available when the computer is idling. The higher the figure the better. If it showed 00 in a previous test then I guess that some scans or updates were running. The test must be made with the computer idling.

30 odd processes is nothing unusual. However, you mentioned a number of antimalware programs. Please do not allow more then one AV and one antispyware to run in the background. If your Symantec is both AV and antispywatre let it be the only program running in the background. The other perograms should be updated and run manually.

Skeptic,

I want to thank you for the generous expenditure of time, effort and expertise in helping me. I've been able to run most of the checks and fixes that you proposed (including trying to check and repair the HD). I'm not sure what worked, but thus far my machine is running somewhat cleaner and, significantly, crashing a lot less. That's the critical thing. I have not used it on the road yet for the acid test, but it is an improvement in any case.

If you keep a log for yourself, feel free to put this case in the "sorted" category. :whistling: However, I may come back to you if I find I was premature in my congratulations! Thanks again. I'm sure I'll meet you in other posts (as I have three computers so lots of opportunities.)

Thanks again for this great public service.
