I am using Dell Inspiron. Its really wierd that my laptop kept shutting down on its own on windows 8.1 but works completely fine on windows 7. This is not a overheating issue as my fan is fine. I clean it ocassionaly with a can of compressed air.
Also, when I booted in windows 7 this was the error I got on my taskbar: There is a problem with your battery so computer might shutdown suddenly.
If that is the case then why Windows 8.1 cant take it and 7 can?
I also Googled about possible reasons so I tried removing the battery for sometime & charging it but laptop shutdown anyway.
Please help.
Questioner
my dell inspiron restarts without any reason. Only thing noticeable is fan, at its peaks before shut down. it looks like heat up issue due to clotted passageways, and if it is how can I clean up my laptop's radiator ?

Power it off. Remove battery, take off mains (AC) power. Press power button a few times to make sure there's no significant energy stored somewhere.
I recommend compressed air, the canned version (that retailers won't sell to minors in the United States.)
If you must, use a vacuum cleaner in reverse...make sure you can vouch for the quality of air, though. You don't want to be blowing more dust in the thing.
Never use a compressed air hose from a Gas Station / Service station. That air is not clean and you will be blowing some very nasty things into your laptop, such as small fragments of metal.

Basically, undo the cover plate with the screws shown:
Undo the 5 screws to take out the thermal transfer thingy. The black end part (2) is a filter. It is tricky and mostly unnecessary to get to the fan itself. I've found that the compressed air is unnecessary as the filter does a great job of collecting stuff. I live with a hairy dog and removed lots of hair from the filter and found the fan blades fairly free.
