Rockies Fan in Diapers

Feeling accomplished & yet frustrated at the same time. I opened up my Desktop & replaced my computer's fan, because my computer would up & shut off without warning & then there would briefly be a burnt smell coming from the tower...The fan might have been part of the issue, but now I know that it also needs a new power supply. I hope that when I can afford it, that I can replace that on my own too....
