i got my pc almost 3 yrs ago and now its full of dust. normally ppl will take all the component inside one by one clean it thoroughly. however, i dun wish to take out all the component as some ppl said "before you take out all the component for cleaning, the pc works perfectly fine, but after u take out all component and clean it and put back inside chasis, the pc got problem like slow on turning on, cannot start, performance slow...etc...or any similar problem". So, in order to prevent this and din want to take the risk, can anyone suggest alternative solution to remove the dust inside chasis without taking out the component?

Solution that i can think of:
1-> use blower(not sure the name is correct or not)
2-> send to shops or any services that provide cleaning (preferably not to choose this option)
3-> get suggestions from this thread from ppl that have experienced/tried to clean the chasis without taking out the component.

thx in advance.

hair dryer only produce hot air and slow air flow.
