Hello Grolgan & everyone, sorry to join in your topic but I have the EXACT same computer as you do & so I thought its better to post here than a new topic.
I'v got this Gateway computer for about 3months now and suddently today, it just started shutting down by itself and its so frustrating. At first, it shut down in about 2-5mins when I play a game (Fallout 3) and I thought it was just that game, but I tried another game I had that worked fine, and unfortunately that game had start to cause the computer to shut down too. I tried to research a solution but no luck.
I don't know if its overheating or a virus, but I downloaded SpeedFan & here is the status:
And when I run the game fallout 3, it usually go up to 80c ish then shut down...but I don't think it should?
Lastly, it usually shut down when playing games, now lately it also happens while surfing internet, etc. but just take longer. so I had to rush & type this message with the fear of my computer shuttign down on me x_x
Thanks in advance.
