sony-vaio

My laptop a sony vaio VGN-NW11S http://www.trustedreviews.com/Sony-VAIO-VGN-NW11S-S---15-5in-Laptop_Laptop_review.

Everytime i turn it on, in safe mode or not, if i try to open an application i.e. run a process such as google chrome or event viewer, defrag, virus scan, it completely turns off without warning, nor giving a trace of events the next time I switch it on.

Apart from that, I had worries it might be my battery or power supply but I dont think it is that, I took the laptop apart cleaning fans etc. and have ordered some cpu paste as I checked to see the condition of the processor. I will post to see if re-applying the paste works.

One more thing, when the heavy processes kick in, the fan starts to make a lot of noise, maybe trying to cool down the CPU?

Any ideas on what else it could be and what I could do to test what is wrong?

disparity between `top`'s given CPU % and process CPU usage total

as seen on Super User - Search for 'Super User'
I've noticed that there are sometimes (large) differences between the reported total CPU usage and a summation of the per-process CPU utilization given by apps like top and wmtop. As an example: I recently ran a git filter-branch --index-filter on a fairly large repo, with the index-filter command… >>> More

I have a Ubuntu 12.04 server which sometimes dies completely - no SSH, no ping, nothing until it is physically rebooted. After the reboot, I see in syslog that the oom-killer killed, well, pretty much everything. There's a lot of detailed memory usage information in them. How do I read these logs… >>> More
