This isn't the place to be asking such questions as it has nothing to do
with getting hardware to run under XP.

However, you give us little to go on - do you know what the function of the
CMOS battery is (obviously not or you wouldn't be suspecting it). All it
does is provide power to the CMOS chip (the little rectangular chip on the
motherboard that stores the BIOS settings when the system is off).

When you switch the system on is there any activity at all? Does the power
supply fan spin up? Are there any beeps (these will give us an indication of
what the problem might be, though they can vary from motherboard to
motherboard). A series of long beeps, about a second apart, could indicate a
RAM problem, a high pitched 'nee-naw' is a definite sign that the processor
is overheating; one long followed by one short beep is (usually) indicative
of a problem with the graphics card (if you have one, rather than an
on-board chip).

If the PSU spins up, and you don't hear any beeps, then I'm not really
sure - hardware isn't really my forte. Have you made any changes to internal
hardware? Added any new cards? Added RAM or changed the CPU of late?

button.

i haven't installed any hardware but my cmos battery has
been giving my problems.

How do you know the CMOS battery's been giving you problems when you don't
even know what it is? The computer, as I stated before, wouldn't refuse to
power up because of a dead CMOS battery. Suggest you take the system to a
qualified technician - *DO NOT* attempt to do anything yourself as you could
end up doing further damage as it's blatantly obvious that you don't know
what you're doing.

you power supply has died. A CMOS batt will NOT prevent a boot. You
need to seek assistance from someone that has more knowledge of
computers than you do. Your post indicates that you are not very
computer literate, and you may things worse by mucking about.

Isn't that - more or less - what I just said;o)...I'm not sure it is the
PSU - she didn't answer my question about whether it spins up or not...;o)

Your power cord might be slightly loose. With one computer I had, I
needed to prop the cord on a wooden animal (a giraffe) to keep it from
sagging.

I think we're *WAY* beyond a loose power cable here...;o)

Yes..you said it first...however my news feed service was down with a
server outage for a while and didn't get caught up right away. I
hope for the OP that it is just her PSU, as that is an easy fix.

I hate top-posters - Robert, please learn to bottom post - there's nothing
so illogical as top posting! ;o)

The thing is though, there are PSUs and PSUs (as I know from personal
experience with a client's system. She had a dime store power supply that
had failed - and taken the motherboard, RAM, CPU and graphics card with it.
That little bit of 'economy' ended up costing her £450 in replacement
parts). If it was a decent PSU (Enermax, Antec and there is another, more
expensive, brand that isn't available over here that I forget the name of)
then its fail-safe mechanism would have kicked in and it would have died a
graceful death - sacrificing itself for the sake of the rest of the system.
However, if she had a dime store PSU then she may not fare so well. This is
why, if anyone asks me to put a system together for them, I always budget
for an Antec PSU - not cheap (+/- £60), but it'll save a lot of money and
grief in the long run.
