Power to pc but nothing else


R

Ron

I went away for all of last week and shut down my pc in the usual way
and also switched of the power at the mains as well. On my return
when I switched it back on, it starts up as soon as I turn the mains
on at the wall socket. The power pack starts, the fans on the power
pack, cpu and motherboard run, the keyboard and mouse light up, the
dvd/cd drives light up but it does nothing else. No beep, no hard
drives, no signal to the monitor, no response from the power button. I
also can’t shut it down at all other than by the mains on off switch.
I have removed every lead and plugin component from the motherboard,
including the bios battery, and one by one reconnected each trying to
power up each time but I just get the same thing.

I seem to be getting power to the motherboard Gigabyte GA-81PE1000
with P4 3.0Ghz proccessor as the fans on the board run but I am now
out of ideas.

Everything you report points towards a hardware issue. You do not even
mention the word "Windows". The experts in
microsoft.public.windowsxp.hardware might be best qualified to provide
advice.

Is there any evidence elsewhere in the house of there having been an
electrical problem, e.g., clocks not at the right time, appliances
needing to be reset, etc.?

In your place I would take the RAM chips to a PC shop
that can test them reliably. A single bad RAM unit can
have effects like this.

sounds like a difficult
issue to figure out.

what I first try is to
boot into the bios
and ensure that the
time and devices are
are recognized.

if the bios time is incorrect,
and the device settings are
blanked out, then it is likely
the cmos battery went bad.

if however, your bios
settings are ok and still
can't get the system to
boot via the hard drive,

then you will likely have
to boot with a xp cd and
bypass the hard drive.

(to do the above you may
need to re enter the bios
and change the primary
boot device to cd)

then at the xp setup screen
launch the repair/recovery
console and see if you get
to a disk prompt.

if so, then I would run a

fixmbr
chkdsk /r
fixboot

then exit, remove cd
and try to boot via hard
drives.

Forgot to mention
I am running Windows XP pro on a 7 year old, home built pc with 2mb
ram.
Recently tried Windows 7 but did not like it and reformatted and
reinstalled XP.

Can't get this far a there is no activity at all other than the power
supply.
No signal to the monitor.

hmm?

it is likely that the monitor
and hard disks would
function on a different
system.

so it sounds to me that
your bios is not detecting
your hardware.

seemingly you should
be able to hold down
either the del key or
f2 key immediately after
pressing the power button
on in order to load up the
bios setup page

but if you can't even get into
the bios then perhaps
the power supply is the
problem

Or you left the modem plugged into the phone line and had lightning storms
while you were away? Phone lines are the usual method of surges and spikes
that can cause damage.
But the advice to check with the hardware group was good; that's really
where you need to go. They'll know to ask you if the mobo LED, PSU LED, etc.
are lit, what color they are and all that good stuff. I'm going to guess
you either have something shorted killing a power rail or a missing voltage
from the power supply. But try the other group for better considerations.

HTH,

Try removing and reseating the memory modules. Also, you might test or
simply replace the power supply. If neither of these help, check the mother-
board manual for "BIOS Rescue".
