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?

Re: Shuttle XPC XB51G Barebones - no power
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.

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.
u did not said ur mother board vander name and chipset. because some mother board can not star if CMOS battery expire. remove CMOS battery check it voltage bellow 3V or not if it's voltage bellow 3V then replace it. and try to trun on ur shuttle.
