No power after switch off main
Posted on 2004-10-23
i got this very strange problem.
my motherboard is dvd266-r which i purchase from someone else.
after i setup everything, the motherboard detects my dual PIII 866 mhz cpu as dual PIII 433 mhz.
as such i modify the settings manually to make it dual PIII 866 mhz.
everything works fine except that everytime when i power off the main switch on the wall and switch it on again, the computer wouldn't be able to boot up again.
it is as though there is no power to the computer (fan not on, no led lights, etc).
to solve this, i had to either reset my cmos jumper or totally remove my cmos battery in order for it to be "able to receive power" and boot up.
The strange thing is that if i just power down my computer without switching off the main switch on the wall, everything would be fine. I would be able to press the power-on switch on my computer and boot it up as normal. Once i switch off the main switch on the wall and later power it on again, pressing the power-on switch on my computer will no longer work.
anyone encounter same problem before?
