I have a Packard bell pc that is not working, I have stripped it down to
just the mother board and a working graphics card from another pc, a monitor
that also works from the other pc and keyboard and mouse also from the other
pc. and a hard drive from the other pc, still it does not work any ideas
what is wrong? yes I know the motherboard is at fault, but what?
also the is intermittent about starting the hard drive, so I have used a
power box from another pc also!!

and the monitor is not coming on, it stays in standby, but when I turn pc
off and unplug the monitor from the pc and turn the monitor on it is ok.

now it must be something to do with the power on the board but is this
mother board a lost cause or can it be fixed?

thanks for any help that is given.

I am not trying to be smart but Packard Bell hasn't been made in how many
years not? Junk the system and purchase a new one.

You didn't state the CPU, Memory, original HDD size etc. but I would assume
it is at least 4 years old and not worth upgrading or repairing. Salvage
what you can and junk the MB & power supply.
 
Possible causes are so numerous it would be ridiculous to even guess. Is the
oscillator oscillating?

Was it working and then stopped suddenly? Do you get any beeps when you try to
boot the system? If it didn't stop as a result of any hardware changes, it
sounds as if your motherboard could have gone bad. Unfortunately, that does
happen occasionally. Motherboards can sometimes short out on the case, but that
doesn't usually happen unless there's a physical configuration change of some
sort.

A number of people who build systems professionally regularly check out
alt.comp.hardware.pc-homebuilt. You may want to ask about this problem there if
your ISP's news server has that group available.

Monitors do that, if they get no signal. if the motherboard isn't
running, there won't be any signal. If the video card or memory are bad,
the PC speaker will normally beep (in a pattern which relates to the
fault). If the motherboard is bad, very little of interest happens at
all.

it's a lost cause. Even the motherboard makers don't usually repair
them, they just bin them and build a new one. The tools you need to
debug, and repair, a modern multi-layer motherboard, with high density
surface mount components on run to 10s of K$, add manpower at $20+ an
hour .. whereas they can build a new board for $25 or so.

Toss it away .. new motherboard, PSU, memory, CPU, will set you back
about $200, and you'll have a much nicer PC. if you can't afford $200,
try ebay, people are throwing away nicer PCs than that one probably is.
 
I am not sure of the CPU or memory size, but removed the memory chip, and
also unplugged the keyboard and mouse expecting it to beep, even with the
monitor unplugged still nothing, and the hard drive out it still had no
life,

this is the first time this has happened where I can not find out exactly
what is wrong and I don't want to give up on it just yet.

yes the CPU fan is ok, but I will check the CPU.

also when the monitor is connected and I turn it on and the pc on, the
monitor is still is standby mode, but when I unplug the monitor and turn
the monitor ion by itself it is ok, it shows the NO SIGNAL screen

in short it all points to the mother board but what on the motherboard? I
will try the CPU later in the morning,

thanks for your replies BTW
