Hi vanillarose

You need to provide information about your notebook such as the brand Dell or HP etc, provide the model name or series number (not serial) providing these details will enable others to better assist you.

As the notebook actually shut down it suggests that it is not a screen or driver issue, heat causes many types of issue and this is a classic example, please do not attempt using the notebook again until you have done some checks that we will suggest once we have the requested notebook details.

Within a matter of seconds the CPU will be too hot to touch and the more the video chip is used the hotter that also becomes.
Cleaning out notebooks correctly is not a simple task and to do a thorough job is not something that the average user should undertake, see guide http://paulov.com/20...cooling-system/ if the cooling fan has failed it is only a matter of time before the CPU and other components fry, can you at any time hear the cooling fan operating?
It is possible to do a partial clean using canned compressed air in short blasts through exhaust vents and the opening you have when removing the Ram cover and hard drive etc.

I won`t suggest anything further until you confirm whether the cooling fan is working or not.

Good news that the fan works :thumbsup:
Clearing out the dust as I described earlier using canned compressed air is strongly recommended as a starting point, I would also remove the HDD (hard drive) and blast some air through that opening, remove the Ram, blow out the slots and replace the Ram securely but try booting up the notebook before you replace the HDD and see if the notebook stays on.

NB: Just a cautionary note, when you use canned compressed air do not upend the can as it is possible for fluid to be emitted.

Sorry but that will not be adequate as it takes short and powerful blasts to do even a half decent clean, see http://www.walmart.c...oz-Can/14931442 for an example.

One of the suggestions to make after the cleaning would be to remove the battery and try booting with only the AC adapter powering the notebook, if no change then remove the AC adapter replace the battery and try booting up again to see if the notebook will function correctly.
When you do the cleaning while you have the Ram and battery removed press and hold down the power button fo 30 seconds, this will dispel any static charge that may have built up in the system.
