I'm looking at a computer for a client, and the problem is that the computer will not physically turn on.
I think that it may be the power supply, as when it is plugged in, a light will come on, and an internal fan will spin for the space of half a second.
After this, the light will go off, and the computer will appear dead.
I have tried pressing the power button, and this has no success either.
Would you think this was the power supply, or maybe something else, ie; the motherboard?
Thanks in advance,

I know that thus might sound sort of far fetched but about a year ago I was replacing the graphics card in my gaming rig. And when I installed the new one the computer powered up for a few seconds with all the fans spinning and then would just die, no beeps or nothing. It turned out to be a bad graphics card if the computer has a dedicated one maybe try removing the card and reboot the computer. Otherwise, my guess would be that it is the power supply.

If the PSU powers on and off subsequently, I'd say... short-circuit? Somewhere around components...

I had a very similar issue a few months back. It was an old XP tower and it would only turn on for a second or so and then power off again. I replaced the power supply and then it worked perfectly.

I had this problem with my PSU when I first bought it. I thought it was dead but did some searching and found out by sticking a paperclip in the PSU you can bring it back to life.
Google "run power supply without motherboard" and click the "dslreports" link.
I can't guarantee this will fix the problem but I've had NO problems since I did this.
Once my PSU short circuited again but it was when I didn't plug something in correctly. The PC then booted fine after it was back in.
Any questions, ask :)

i've had this same issue with RAM going bad, or the RAM slot going bad, alternate ram chips and slots to rule it out.
also to find out if it's a power supply issue, disconnect the drives, and power on without any drive or extras connected, just the motherboard and graphics card and see if it powers up. this can also rule out any bad drives by connecting them up 1 at a time and powering on.
