Bad earthing could, theoretically cause this, but there are many possible causes.
You've suggested what to check but could you enlighten me on the possible causes, apart from a broken power switch ?

Check the following:
1) That the grounding cable (the "middle" one) on the PSU is really connected to earth (I have stumbled across some el-cheapo UPS that break this connection).
How could this cause the problem I'm experiencing ?
Here in Japan, power outlets rarely have an earth connection, I guess earth is floating for my board. It's never been a problem before though.

2) That the "On" switch is not shorting itself (moisture? rust?).
I will check.

3) That the PSU itself is not dying or full of crap (moist dust/fur do not make great insulators). Check the stability of the voltage, especially on the +5V ramp and and +5V SB (pin 9 on the motherboard connector, color-coded purple IIRC).
The PSU is fairly new so it is less likely to be the source of the problem.
Thanks for the suggestions.
