While I can't be 100% sure, I'd suspect the power supply. It's an old, low budget model and not very good to begin with.

Ok i will try to replace the power supply

Check all the connections on the mobo , some may have move a tiny bit as heat has circulated round the case.
I caught the edge of a fan plug whilst removing dust , just enough to stop the fan working.
The pc shut down because it could not find all the component's it was looking for.
