why my computer's fan making large noise at start up time?
A week ago everything was running fine 3,4 days ago i notice that it is making much more noise than it should. It seems that it is CPU's fan's noise.Most probably dust is responsible for this.there is a lot of dust inside my CPU. This may hamper hardware badly(as i have seen in some websites). What should i do? can i solve this by my self or i need to go to computer repair shop.
one argument that this sound is not of fan is that, If it is sound of fan then it should start blowing very fast with noise after opening computer for long time since it blows when processor warms. But one can say that fan is not in well working state so that's why it is making this much sound, After all these are my arguments. I may wrong. what you think is possible reason for this problem.
thanks to all those who reply.
