I am back at home again. And my computer is back up in full working order. This makes me happy.

I have to say, though, PSUs have got to be amongst the most obnoxious of computer parts to replace. For those who don't know, the process goes something like this: First you open up the case. Then you have to unscrew the PSU. Then you have to observe all the wires coming out of the PSU and pull them out of where they're stuck into other components, making a mental note of what goes where so you don't screw things up when you plug in the new one. Then you figure out the best way to remove the PSU from the case, since most of the obvious ways require having either three hands, or the ability to move things through solid matter. Having done that, you then have to perform the same trick in reverse to get the new one in place. Then comes the rewiring, at which point you curse because the wires on the new one are a bit shorter than the one on the broken one you've just taken out, so won't reach to where you want to go. As such, you then unscrew one of the hard drives and move it into a different drive bay, closer to the PSU so that your wire will reach. If you have a goat available, this is a good time to sacrifice it. After getting all the wires in place, you then need to plug the IDE cables back in, since you invariably knocked one of them out while wrestling with the other wires. Once all the wires are in place, you plug the power lead, monitor(s), mouse and keyboard into the back of the computer (which usually involves at least one act of contortion to reach the cables and/or the plug sockets), and turn it on. This is an important step, because you can guarantee that if you don't test that everything is working and instead put the sides and top back on the case and screw everything back in having just assumed that you got everything right, then you will definitely have made some dumb mistake somewhere, nothing will work, and you will have to unscrew everything, at a cost of yet more time. Having confirmed everything works, you the have to take all the leads out of the back of the computer, move it over to a place where the back is accessible, screw the PSU into the case, replace the outer bits of case, and you're done. Then it's just a case of untangling the 17 wires that have magically formed into a knot behind your computer, plug them back in, and turn on.

Blah. Oh well, at least I've never yet had to replace a motherboard. And at least PSUs are cheap.

Motherboards involve all that, a copious amount of sweat, and the Mission: Impossible theme playing in the background.

Glad you're up and running again, anyway. How's the new monitor?

The new monitor is wonderfully awesome and awesomely wonderful. NEC 90GX2. 19", TFT, DVI. Very sharp picture, nice and bright and clear, very small and sleek design. Presuming that nothing goes wrong, I expect to be asking to have its babies around this time next week.

*drools* I have my own nice monitors, and yet I'm still lusting. If you have its babies, can I be a godparent? :D

Well, I'd have to ask it, of course. Choosing godparents is definitely something for both parents to discuss. But as far as I'm concerned, sure.

*sniffles happily* I feel most honoured.

Can provide a good home for any baby 19" TFT monitors (7" TFT monitors?) that you might be putting up for adoption...

Wow, you're going to wait a whole week? How very restrained. If it was me, I wouldn't even bother taking it out to dinner first.

Well you know me. I'm a veritable paragon of decorum and etiquette and other such fancy things.

"If you have a goat available, this is a good time to sacrifice it."

I think Frank just ran and hid....

Given some of the errors that I've been seeing on the site lately, Frank should probably stay hidden lest LJ sacrifice him.

You missed out the (thankfully increasily slight) possibility that you might come across an AT power connector, in the traditional two seperate plugs, with no documentation to hand as to which goes where.

Slightly more possible, but even more likely to let the magic blue smoke out, is my all-time favourite piece of design insanity: the Dell proprietry ATX pinout[1]. Replacing motherboards is fun compared to this, assuming whoever built the thing in the first place didn't cross-thread one of the screws requiring it to be drilled out.

[1] Thankfully they saw the error of their ways, and this one tends to be limited to PII/early-PIII-era machines.

Wow. The Dell people who thought up that one must have been on some seriously powerful crack. That's completely insane

Indeed. I made a bench power supply out of a spare nonstandardly-shaped[1] Dell PSU a while ago (basically a case of mount it in a sensible box with load resistors to keep the regulator happy and something to switch it on and off with), and was under the mistaken impression that it was buggered for ages because it wouldn't respond to the 'on' signal. It eventually dawned on me that the wire colours weren't consistent with what my ATX pinout cheatnotes said. Madness.

[1] Yes, they do that too - though it was long and thin to fit a slimline desktop case, so not completely gratuitous

*not to self- get a sacrificial goat on standby*
