Today, i look to my computer that i have used since 3 years ago and still work until today. So i have initiative to give little treatment to my computer. After i open the casing of my computer i found to much dust in my computer. So, i open my tools bag and try to find paint brush and starting to clean up my computer, while i am cleaning i found that the result is not maximum that i expected because there are little part that i can't reach and still dusty.
Finally, i brought that my computer to my neighbor who have an air compressor in his workshop. After i ask his permit to use his air compressor then i start to cleaning up my computer and you know what ? My computer it is completely clean.
