Pioneer Dreabook 8252d turning off randomly

I've had my Pioneer Dreambook 8252D for a little over a year now, and as of around 3 weeks ago it has suddenly started turning off. I wasn't doing anything demanding, and it turned off suddenly, like I had held my finger down on the power button. I have taken the back off and nothing looks out of place. I also noticed a pattern that sometimes happens. I ran it in safe mode for half an hour and was running an avg scan through command prompt when it turned off, then it turned off 1-2 seconds after the light turning green around 3-4 times, before I was able to load it into windows. This time I ran an avg scan for about half an hour before it turned off and I turned it on 14 times before it loaded past 3 seconds. This time it got to the login screen before it turned off.

It isn't dusty, but me and a mate will clean it out now just incase. I don't think it's a virus either, because I managed to get a quick scan in before it turned off, with no threats - could be wrong though.

If nothing turns up I'm going to have to opt for a complete rebuild, which I really don't want to need to do. Hope you guys can dig something up.

Problem is fixed, GPU was pretty much fucked.

look in the registry keys, there might be a program that opens on start up that uses the shutdown -s command. Basically this tells your computer to shut off once it loads, it relies on a bat or some people call it a batch file. :)

Maybe a program was made to install it to the registry, it can be a tricky fix.

but easy once you learn how

@tigafied i already tested that, it was  actually the temps, the GPU outtake fan was not spinning.

@LukyGamer This notebooks are Mitac 8252d. Gpu might have been the problem, but only the end result. In fact , the system cooler, that cools the cpu, north bridge and finally the gpu, it only starts at 60 degrees Celsius of CPU temperature and by that, the gpu has 72 . You need Notebook Hardware Control with ACPI Bios linkage driver to be able to set-up the cooler to start earlier.

I already requested at mitac uk service this driver.

They purchase products from China's no name brands and simply re branded. Service is crap, when I was stupid enough to purchase a product from them they offered pot of gold, when I received product that was pot of crap. DO NOT BUY FROM THEM.
