*Poof*
June 9th, 2009
Last week I was catching up on some shows I recorded on my MythTV box (essentially a computer made into a home made Tivo) when the picture just disappeared. When I rebooted, it didn’t even show the BIOS, so I figured the video card died. I built the box back in 2004 and it’s always on, so it actually had a really good run.
While I’m waiting for the replacement card to arrive from newegg.com, I decided to take the existing card out, make sure the fan still spun, and reseat it back into the motherboard. It was worth a shot.
The inside of the box itself was a disaster. I try to air dust my desktops about once a month, but apparently I’m behind on this one. I tried to take a picture, but it doesn’t do it justice. I’ll simply point out that there is a dead spider inside.
Whenever I’m dealing with a piece of hardware that doesn’t work, I inevitably turn it around in my hands looking for… well, I don’t know what I’m looking for. I’m not an engineer, so short of seeing smoke coming from a part, no amount of physical inspection has ever yielded results.
This time was a bit different. Take a look at the second column of cylinders on the card below. I don’t know what they are or what they do, but I’m pretty sure the tops aren’t supposed to be blown out like that. The one closest to the camera even had what looked like ash coming out of it.
Might be time to plug in some of the fans I disabled to make the box run quieter. 
And as a public service announcement, airdust your computer. It will love you for it.
