GPU Blown?

I built my computer about a year ago and I think my ATI 5870 finally blew.

I was playing around on Runes of Magic and all of a sudden black screen with the no input message on Monitor. The fan on the GPU started getting really loud. as well as the only way I can turn off the CPU now is by turning off the actual power supply.

The Case seems to turn on and the fans turn. The Lighted bios buttons on the mother board come on. However, when I try to turn the computer off with the actual case power switch nothing happens.

Is this a GPU issue or could it be something else? This was my first build so I am fairly new at trouble shooting,

I did take the GPU out and blew it out with compressed air and when I put it back in the fan did not spin anymore either.


Please let me know if more info is needed again Im new at trouble shooting so not exactly sure what info is needed,
