I one time burned my pc

So when i had my frist pc i never really cleaned out the dusk out of it. And it worked fine for about two and a half years and than one day it wouldn't start, And to make things worse it was a few days before an imporant physics test. Luckly i still had my much older pc from my dad so i still could counite to study for the test. But it's still sad i buret it down T_T

Moral of the story: clean the dusk from your pc.
Also thank you dad for buying me a new one.
