Shuttle Dead: Power supply problem, or otherwise?

Ahoy,

This isn't unlike the question Ebiggs just posted, but I don't want to hijack his thread.

So, around this time last year I sold my old Shuttle SS51G to my girlfriend's family and in doing so I apparently became their tech support. I got a call from her Mom Friday night saying that the computer isn't working, it won't turn on. I went over yesterday evening to have a look, and as she said, it is lifeless. Hit the power switch and it does nothing. No beeps, no fans or drives spinning up, nothing comes up on the monitor, no lights on the case or mobo, nothing at all.

The question is, is this the likely fault of a bad PSU? or could it be something else.

I know the Shuttles have a bit of a reputation of cooking PSU's, so I'm pretty quick to jump to that conclusion. It's just a weak 200w unit. I was just about to order a 250W replacement but I don't want to end up spending their money on a component that isn't going to fix the issue. I feel bad enough as it is selling it to them with only a year of life left in it (although, I probably let it go to them for half of it's worth anyways). The biggest fear I have is that it's the mobo, or that the PSU may have taken the mobo with it. I'm pretty sure that the particular one in there (FS51...I think) is no longer available from Shuttle.
 
When my PSU went out it gave off a pretty strong smell, so I guess you can sniff around. I think it filled up the whole room.
 
If it appears to be completely lifeless the first thing to check is the power coming into the machine. Does the outlet work (plug a lamp into it to test)? Is the line cord securely plugged into the power supply? Et cetera... I've been nailed by that kind of thing a few times in the past.
 
Ya, I did check that. I also checked the switch on the front by disconnecting and shorting the two leads. It's nothing quite that simple.
 
Take out the CMOS battery and try it?

Disconnect everything from the PSU, short-start it and if that doesn't make the PSU start, it's dead!
 
It's probably the PSU, but it would be better to try it before buying it. Can't you go to a computer store and ask to test it?
 
Thanks for the suggestions.

That may be on the todo list for tomorrow night when I've promised to go back over and troubleshoot it a little more, if I can't figure it out on my own. The computer stores here are absolute criminals though. :grumpy:

I'm thinking of yanking the PSU out of my current computer and taking that over to see if it'll boot with that one hooked up externally. Then, pending their approval, I'll probably just get a cheap 400W unit for $30-$40 and earth cable it to the case to keep everything grounded, rather than drop $100 on a new PC-40 PSU to fit the case. They don't make use of the shuttle's portability anyways.
 
ya... it was the PSU.
Tried short starting it with all devices connected: ...nothing. Removed devices 1 by 1 and kept trying to short start it: ...still nothing.
Plug in the PSU donated by my current computer and the little shuttle came whirring to life.



Case Closed.
