Shuttle XPC XB51G Barebones - no power

My computer was shut down unexpectedly and when I went to power back on the power switch does not work. I see no visible damage. I press the power switch or the reset switch and get nothing. Not sure if this is a power supply problem or switch problem or hopefully not a motherboard problem. Any ideas?

    Thanks for the advice. I tested the PSU in another computer and nothing so I ordered a new PSU for the Shuttle.

    Hi - I am using SN95G5 barebone ( with 50GB 10000 rpm primary hdd, 250 gb secondary hdd, ATIx 800pro graphic card). One day when I wanted to start my machine, press the power supply button and can see hdd led gets on and sounds comes like hummmmm!! Every this is getting powered up, even still. But no boot up nothing coming up on screen.

    Sounds like PSU problem. If that is the case then I need slientX 240W PSU. I am not sure from where I can opt from?

    Any help would be much appreciated!!!

    Many many thanks in advance,

I think you will find your PSU has gone faulty, they are very cheap these days, I would guess at the PSU and replace it "On Spec" with a similar one. Remove the four PSU screws around by the Fan at back. Unplug it from The motherboard noting connections, can only go one way thogh. Take the PSU to ya local repair shop and get another... put new one in connect up to MB and power up. If ya lucky.. ya solved ya problem. Or better still see if you can test it with another one B4 buying another.

Reset cmos, doesn't switch on

Plug out your pc, hold the power button for a few seconds and then take out the battery. Then wait a few minutes and put the battery back in. This should reset your cmos. If this doesn't help then the problem might be a corrupt bios, defective psu, faulty cpu or memory.

I had the same problem with 2 of these systems.
You need to replace the power supply.
I know it's a weird problem. It seems like it shouldn't start at all.
But it solved the problem with both of the systems.

here is a link for the power supply at a few stores:

Hope this helps.
