Hi :)
sometimes I need to isolate the PC from the mains and then turn it on
again, before it can boot. After startup did work, there are no issues.
Does your monitor have a separate PSU? I ask as this computer started
behaving erratically, to the extent that I set up a spare on to use.
Just before switching over there was a 'pop' from the monitor PSU and it
died. Using an alternative monitor stopped all the computer problems!
It's a bit bizarre, but it's possible it might not be the computer at
all at fault.
The CTR has got it's own PSU, the PPPoE ADSL modem has got it's own
power supply too and they were connected before I added new hardware,
but I additionally connected my old parallel port HP DeskJet 600 with
it's own power supply and it's turned of when booting.
I still suspect that for the boot process the 450W/230V2A PSU is to
weak. I suspect when measuring the current consumption at the mains side
of the PSU, everything would be ok. I suspect that behind the voltage
stabilisers there might be an issue sometimes.
I wonder if there's a monitoring or if there's a way to turn of power at
boot automatically for e.g. USB and to turn it on near the end of the
startup. I read something about wakeup, but without explanation, since I
guess a wakeup is doing something different.
Because it only happens sometimes, i can't just disconnect one hardware
after the other to make tests.
But you're right, I'm not sure if the PSU is simply to weak, might be
something else.
Thanks,
Ralf
