Helping people with computers... one answer at a time.
Some laptops don't have the proper ventilation to handle a high CPU load for a length of time, which causes them to protectively shut down or crash.
I gave my wife a Nokia netbook running the starter Windows 7 about 2 1/2 years ago. It's increasingly freezing up. It used to be once in a while, but now it's doing it after five minutes or so of operation. It does not seem to make a difference if it's running on the battery or AC. However, it does get very hot. I took the battery and ran it only on the AC and it is still very hot. Any ideas? By the way, all she does via Wi-Fi is surf the net and looks at email and Facebook. We don't know how to use Twitter (if you can believe that).
In this excerpt from Answercast #57, I look at a case where it appears that a CPU load on a computer is causing it to overheat and crash.
Oh, I can believe it. You're not alone in not necessarily paying attention to Twitter.
My suspicion is that your computer is overheating. The fact that you say that it's getting hot... many computers are such that if they get too hot for too long, they'll actually shut down. They'll either crash or the motherboard will proactively and preventively shut the computer down to prevent it from damaging itself further.
Now, the question is, of course, why is it overheating? What I'm going to suggest you do is fire up Process Explorer. I have an article called, "Who's hogging all the CPU?" and I'm going to point you at that:
You'll download Process Explorer;
You'll run it in a way that will highlight which programs are using all of your CPU.
If it turns out that the System Idle Process is using most of your CPU, then I'm wrong; it's not a software issue... it's not something going on with software that's causing too much to be run on your machine.
On the other hand, it is very possible that you may see a program or two consistently at the top of the list trying to use all available CPU for some reason or another.
That would potentially cause your computer to overheat.
Normally, computers are more than happy to do that for awhile. But typically in a situation like this, I have seen software (either malware or software that just has bugs in it) that causes it to use all of the CPU constantly, continuously.
Some laptops don't have the proper ventilation to handle it for that length of time, and they crash.
So, take a look at Process Explorer. See what bubbles up to the top of the list. That's the program you'd then start looking into. It is very possible that that program (at the top of the list) is what is fundamentally at the root of this problem.
Now, I say that with the assumption that if all you're doing is surfing the net and looking at email and Facebook, in reality, those shouldn't use a lot of CPU. I mean there might be spikes as certain things get drawn on the screen and so forth, but what you've described is fundamentally things that just don't require a lot of horsepower and a lot of CPU time to accomplish.
So, if there is something that's using up all of your CPU, it's probably not
intentional. It's certainly not required to do what you're doing and it is
something that is basically the next step in your investigation.
