    Sir,
    My Sony vaio Laptop model vgn CR-24G is formatted for dual booting with Windows XP and Vista. It was working fine for more than one year. Now my system is shutting down in between very frequently. It is happening on both OS booting and within 5 to 10 minutes after booting. There is no BSOD it is showing. I think it may be due to the overheating of CPU... bcoz my fan sound is not hearing and no hot air exhaust when the system is powering on and working. How can I confirm whether this is the problem or some other. Plse help

    Regards
    Sree

    Heat and bad power supplies are the most common causes....You should be able to use a compressed ait can to blow the dust out of the fan.

    Hello Steve
    Thank you for your advice. Can dust will stop functioning the fan ? Is there any temp sensor through which the fan cct is controlled and can it also become unserviceable.

    Regards

    If the layer of dust is thick, it can stop a fan, or block the air flow. You should open every compartment and remove all covers and removable devices (drives, batteries, cards) and use the compressed dusting gas (available at most home improvement, electronics, and discount stores) to blast out all the dust. Fans can simply go bad too. But if the notebook has never been cleaned, then dirt would be a problem in any case.
    The speed is controlled by internal sensors in the CPU by the chipset, part of the motherboard. If the controller is disabled, the fan "should" default to running full speed.

    Once clean, consider using a Notebook Cooling Pad w/ext. power supply.
