Although I am far from a computer expert when it comes to hardware it seems to be the fan for the GPU, the fan is loose or constantly falling of lately and when I took a SpeedFan test it said that my GPU is 114 C when being idle. I reckon I have to replace the fan.
lol yes. At that temp the part will fail shortly, don't use your PC again until the fan is reattached. You need to use THERMAL COMPOUND when you re-attach. Try this http://www.newegg.com/Product/Product.aspx?Item=N82E16835100014
plenty of videos on youtube showing how to apply.
Run a monitor like HWMONITOR from CPUID (makers of cpuz) occasionally to see temps. it's free.
There's a chance the graphics card is already toasted, if so the fail will continue until you replace card. Here is a video card ref: http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107.html
