    Hello. My laptop running Windows 7 shuts down periodically for some unknown reason. It doesn't restart. It just shuts down. Lately, it seems to be happening more often. I suspect possible overheating since I hear the fan seemingly working hard more often. But unfortunately I don't have enough knowledge to diagnose the problem. Any help would be appreciated. Please let me know what information I need to supply. If there is a program I can run that gathers all pertinent system information, please let me know and I will install it and get the ball rolling, Thanks in advance.

    Sounds dangerous to me. Is there not a big chance that will blow crud onto the fan and the components that the fan is trying to keep cool?

    I'd check all the vents to make sure they are clear. You are using the laptop on a solid surface, right? Not on something soft, which will block the air flow?

    TerryNet's misgivings about simply blasting air in thru the fan outlets are definitely to be shared.

    The whole object of compressed air is to get at those inside corners and components that may be dirt layered so as to cause them to heat up. For this they need to be exposed so that an air blast can get the dust off and it can then be removed from those parts of the inner casing where it's flown to and where one may touch without danger of harming any micro-components (which shouldn't be touched at all if you don't know what you're doing).

    Additionally to the back blow of muck that TerryNet mentions (which'll only add to the overheating), fans should be subjected to only short burst blasts and those from quite a distance. And the right direction helps. At the same time one should try immobilizing them with a cotton stick by light touch. They're pretty fragile and overspinning may well break a blade and crack their bearings.
