Bugs, bugs, and more bugs. All of the "this can't ever have
worked" variety. Of course they only showed up after
I committed the changes, so they inconvenienced everyone
instead of just me. Bleah.
Had to stop work abruptly when the power-supply fan began
emitting hideous grinding noises. I have the worst luck
with fans... As it was 7PM on a Saturday, I had no option
but to attempt to repair the thing myself. Fortunately, if
you don't mind ignoring the stickers on
the outside of the PSU:
NO USER SERVICEABLE PARTS INSIDE
OPENING WILL VOID YOUR WARRANTY
TURN BACK NOW, FOOL!
it is quite straightforward to extract the fan from the
power supply, dismantle it, and clean out the grit which
causes the hideous grinding noise. The worst part of the
whole exercise was figuring out how to test it. ATX power
supplies don't turn on when you flip the switch, you have to
plug them back into the motherboard and push the software on
button. (Presumably it's possible to put a jumper across
some pins in the big fat connector, instead, but they don't
label them.) Don't plug the hard drives back in, or it will
try to boot.
I'm paranoid, so I pulled everything off the
motherboard before testing: CPU, memory, ribbon cables,
video card, etc. But I didn't unplug the speaker. The
chipset noticed it didn't have a CPU and started beeping
angrily. Scared the cat out of the room.
How does grit get in the fan bearings, you ask? Being as
how my computer sits on the floor, which is covered with
gritty dust, which the fan sucks into the computer, I'm
surprised it didn't
happen earlier. I wonder if you can get air filters for a
