my first post here. I've tried to get to the bottom of the problem myself without much luck so far. I've got an Acer Aspire 5735Z and running Windows Vista. I know its not exactly the newest of laptops but has served me well over the past few years. Recently it has started overheating and switching itself off at times. I have been trying to find the pattern, when playing Candy Crush on facebook is a definite, it seems to switch itself off about 15 minutes after I start playing this (my friend says as its flash driven its high cpu usage therefore makes my laptop shut down as a result of overheating). The past couple of nights I have been able to watch films on my laptop using VLC media player but when I tried to watch videos on youtube it shurt itself off after about 30 minutes. I havent really seen any other pattern to it so far.
I'm not the most technical but have taken the back off my laptop, theres no dust there or on the heatsink and have tried replacing the thermal paste as someone has advised me to do. When it shurts down the left hand side nearest the screen is hotter than it should be and it does sound like a fan is whirring but not sure what to do about any of it.
Its getting pretty frustrating not having a reliable system and I dont want to take it to a computer shop who may charge me the earth for fixing it if i can try and fix it myself. I'd appreciate any help going and if I've been too vague about specs etc please let me know so I can help others hopefully help me!
