I have a Sony Vaio Laptop (Model PCG-K315Z) which seems to be making alot of noise everytime i turn it on. It used to do this occasionally, but now it's almost everytime i turn it on. I'm guessing its overheating because it also gets very hot, but the fans make so much noise. I haven't gotten any error messages but i'm just worried because last time the noise was this constant my laptop crashed and I had to send it away to get fixed.
It's also occasionally suddenly using up 100% CPU even though I have only one or two applications running. I have to close all applications down and wait until the CPU goes down again before doing anything or its very slow.
I'm just wondering what this means. Is there a hardware problem or anything I can do to fix it without having to send it away to get fixed?
Also sorry if this is the wrong forum, I wasn't sure where to post this.
