    Hi guys,

    I just joined. Thank you in advance for any advice.

    I have a Gateway Core 2 Quad 2.4 ghz with 3 gb of ram and Windows Vista.
    I tend to leave my computer on for days sometimes downloading and uploading torrents, editing video and photos, and sharing media with my 360 and ps3.

    Lately, I have noticed that every once in a while the fan noise (like a blow dryer) will be very high and seconds later it turns off by itself (hard, not via windows).

    Any ideas on what I should be looking for? (please let me know how to test for these)

    Possible theories:

    - powersupply fan not working and its overheating? - how would I test for this?


    Again, thanks in advance.

    I use Motherboard Monitor and RivaTuner to give me CPU and video card temperatures. If this only happens when you work with memory intensive graphics (photos) could be video card is overheating.

    Edit.... RivaTuner is a registry editor, don't use it unless you know what you're doing. Also I don't know if using something like that invalidates any Gateway warranties or what so be careful.

    I would tend to think it is overheating. Open the case and give the system a good cleaning with a can of air [available at any computer or office store] Once the system is clean, power ON and check that ALL fans are working. If everything looks OK, then check your temps. I would use either the hardware monitor in the bios [if used] OR speedfan.

    In my case I confirmed that overheating was the likely problem by leaving the case cover off and blowing a house fan directly into the case. When I did that, the crashes did not occur.
