Hi All
I am unable to boot pc on start up. This pc has not been used or connected
for around 3months, when last used was working perfectly. Everything starts
as normal but will not boot.
Is there somrthing I can do or overlooked or could this mean a new motherboard
Thanks

What is the computer doing after it is turned on from a cold start? Does
it POST? If so, then what next? Any messages show up on the screen? How
far into the Windows start up does it get? From Windows XP Logo to logon,
if it got this far?

Right now, the problem be anything, from a dead CMOS battery to a failed
hard drive.
 
Hi Ghostrider
From cold start the computer does not post, checked cmos battery that is ok.
Fans are all running. At this stage would the hard drive come in to the
equation

Start by swapping out the power supply for a known-working one.

Standard caveat: Testing hardware failures often involves swapping out
suspected parts with known-good parts. If you can't do the testing
yourself and/or are uncomfortable opening your computer, take the
machine to a professional computer repair shop (not your local
equivalent of BigStoreUSA). Have all your data backed up before you take
the machine into a shop.

Hi Malke
Sorry in delay replying had problems with ADSL supplier.
However swopped the power supply, HD, internal battery and graphic card
still nothing begining to think it is the motherboard, only thing havent got
spare I can swop.
Shame I dont live near you there in the USA could bring it in for you to
check out. Unfortunatly I live in the UK and winter in the Canary Islands
If any other ideas would be greatful if not thanks for your help once again.

MRRIGGA:
It could very well be a problem with the HDD. I assume you haven't checked
out the HDD to date with a diagnostic utility that's generally available
from the website of the disk's manufacturer. So if you haven't done that
yet, I would advise you to do so.

I believe you indicated in a previous posting that the system had been
working without any problems whatsoever but had been lying dormant over some
months before this problem arose. That's right, yes? So this problem
occurred "out-of-the-blue" so to speak and you have no clue as to why it
happened. That's right, isn't it? No chance, for example, that the PC was
physically moved during that period of inactivity that might have caused the
problem?

Anyway, assuming the drive checks out OK...

You seem to know your way within a PC's innards (incidentally, I'm assuming
you're working with a desktop PC), so do this...

1. Disconnect (uninstall) all the components from the machine with the
exception of your processor, RAM modules, graphics/video card, and the power
supply,

2. Make certain that the heatsink has been properly installed and that the
RAM module(s) & graphics/video card are properly seated. Check these things
*carefully*. And try to determine as best you can that the motherboard is
properly & securely connected to the case.

3. Ensure that if your motherboard contains a 4-pin 12V connector, the
appropriate lead from the PS is connected to it. And make sure you've
connected the CPU fan to the proper connector.

4. Connect your monitor, keyboard & power up.

5. Hopefully you'll get a screen display at this point. It's not important
what's on the screen. All you want is a display. Assuming you do get this
display let the system run for a half hour or so. During this time access
the BIOS and check the temps to determine they're in a normal range.

6. If you do get a screen display there's a good (but not absolute) chance
that the problem is not with any of your basic components.

7. If there's no screen display than you could be dealing with a defective
component which could be any of the ones presently connected. Since you
already changed the PS and graphics/video card it's safe to assume it's not
one of those components. So it could be the processor/heatsink or RAM or
the motherboard itself that's defective or improperly connected.

8. It's possible that the motherboard (although non-defective) is "shorting
out" because it's not properly secured to the case. It's more of a common
problem than one would think but it usually arises in new installations and
not in situations like the one you've described. (That's why I asked you
earlier whether the PC has been physically moved during its period of
inactivity). We frequently learn this when we disconnect the MB from the
case and make all the connections while that component is outside the case.

9. The problem here is as Malke described - the only way for the end-user to
definitively tell what, if any, component is causing the problem at this
stage is to replace the components one-by-one.

9. Anyway, if you *do* get that screen display, continue to add your
components - starting with the HDD & optical drive(s) and see how it goes.

Good luck and let us know how it goes...

Unfortunately you did shotgunning. Even your car mechanic would
find employment difficult if he did that. You swapped power supply
and still don't know if the power supply system is functional.

Solution is to determine what is definitively good - a step by step
procedure. If thinking binary, then you must shotgun. But the world
is ternary. Everything is either 'definitively good', definitively
bad', or unknown. Currently everything in your machine is unknown.
Maybe made exponentially more complex by adding another failure.

Get a 3.5 digit multimeter. In but two minutes, define the power
supply 'system'. Why? Because the two minute procedure provides
numbers in "When your computer dies without warning....." starting 6
Feb 2007 in the newsgroup alt.windows-xp at:

http://techrepublic.com.com/5102-10586-5566528.html
http://www.helpwithpcs.com/courses/power-supply-basics-inc-pinouts.htm

Not only will this 'definitively' define the 'system'. It will also
provide numbers so that better informed posters can provide even more
useful information.

After all that work, you still don't know what is definitively good
or definitively bad. IOW nothing has been accomplished. And nobody
can provide anything but speculation. Why? You provided no numbers.
Get the meter. Use the procedure. Not only get better replies. Also
learn some basics in how your computer works.

Shotgunning may cost you so much money that buying a new machine
would be smarter. But you don't have to shotgun. Work smarter. Get
the meter.
 
Hi Anna
Tried everything you said Changed all components for KNOWN GOOD WORKING
COMPONENTS (as w_tom thinks I am stupid I think he is rude) So thank you for
your time and help I will try a new motherboard if that dont work will have a
few spare parts.

One can be politically correct or one can be honest. Those who
'read into' posts may see emotion. But that emotion does not exist.
Nothing posted made any judgments about any person. The post was
quite clear and technically honest. Shotgunning will result in a more
complex problem, spending money wastefully, will not determine what is
wrong (how to avoid future failures), will not result in useful
replies, take much longer (as already demonstrated), and may not fix
the problem.

Suppose motherboard is replaced and system suddenly works. Was the
failure discovered? Was anything learned? Of course not. Could be
an electrical problem. Could be a mounting problem. Could be a loose
connection. Could be that a defective power supply is made marginal
by a new motherboard so that computer will work (often only
temporarily). Nothing rude in a technical fact. But it is easy to
read insult in blunt honest and technical posts.

Shotgunning takes more time, more money, tends to make the problem
more complex, and is recommended by the many who don't really know how
technology works. No way around that blunt reality. Shotgunning is
also how bad car mechanics end up unemployed. Others have recommended
shotgunning. Shotgunning is more often recommended where a computer
tech does not even know how electiricity works. Again, nothing
insulting. One need not even know how electricity works to be A+
Certified which explains why some only understand how to fix hardware
by shotgunning.

Without numbers from that 3.5 digit multimeter, then every reply can
only be speculation. No insult. Just a technical fact by one who was
doing this stuff for many generations.
 
My apoligises if this may be the case.As you say you have been doing this
stuff for many years. there are some of us who are new and novices at this
game and that is why we post these questions.
We need replys in easy to understand languge not in technology terms that we
can not understand.
Re your paragraph 3. As I explained to Anna I checked mountings electrical
supply and bad connections.
As a novice I would not no which terminals to check for what with my meter
apart from plugs from power supply.
So may I suggest you change your approch to how you answer the posts and do
not put down people who try to help in the best way they can.
I have been a marine engineering officer for many a year and have often had
to try replacements to correct a problem where there is no other way
available.
Shotgunning new word for me must be an American term.

The person called 'rude' made no comments about you. Every comment
was fully technical in nature. Any emotion (rudeness) in that post is
in your head; not in that post.

The post was bluntly technical. Shotgunning is why you have spend
so much time and still have no list of what is 'definitively good' and
what is 'unknown'. Again, the only insult would be your embarrassment
at not having accomplished anything yet.

Again, the post described how to move components and 'systems'
inside that computer from the 'unknown' category to the 'definitively
good' or 'definitely bad' categories. That growing list means
accomplishment. The first thing the informed tech does is use a
multimeter. Even your car mechanic would quickly be unemployed if he
did shotgunning - swapping parts until something works.

Nothing rude about a blunt truth. Since your procedure does not
even provide numbers, then posters that have far more technical
knowledge and experience cannot post a single useful reply. Currently
your replies are all based in speculation. And again, nothing rude
about technical honesty.

w_tom does not think you are stupid. He said quite bluntly that
your so many replies are technically naïve - based only in wild
speculation. Therefore you are talking weeks to identify a suspect
that could have been identified in as little as two minutes.

Your original problem (as described) has nothing to do with hard
drives. How do we know? POST involves a very limited number of
computer components. HD can be completely removed and POST must still
work 100%. But again, the hard drive recommendation demonstrates
what a very informed and bluntly honest poster has posted. Your
replies are chock full of wild speculation. Your replies don't
receive technically informed replies because shotgunning provided
almost no useful information for an informed reply.

Get a 3.5 digit multimeter. In but two minutes, define the power
supply 'system'. Why? Because the two minute procedure provides
numbers in "When your computer dies without warning....." starting 6
Feb 2007 in the newsgroup alt.windows-xp at:
http://tinyurl.com/yvf9vh

Two minutes means numbers so that technically knowledgeable posters
will reply. And again, there was never anything rude in that post -
unless you consider honest bad news to be insulting.

Shotgunning - shoot in all directions in a hope that something gets
hit. That 'wild speculation' procedure is useful only when all other
useful solutions have expired. "When in doubt, punt".

In two minutes with a meter, even a loose connector might have been
located. Numbers from a meter are that powerful as to even find a
loose connector pin that cannot be identified by shaking or pushing
(one loose wire in a connector will not be obvious by 'checking
connectors'). Each test results in a specific answer - 'definitively
xxxx'. If we don't know 'definitively xxxx' for each component,, then
we have accomplished nothing.

Meanwhile, why do we fix things ourselves? Rarely does it save time
or money. We fix things first and foremost to learn. The meter is a
tool almost as essential as a screwdriver when doing electrical work.
When ready to replace something, the meter is the only (inexpensive)
tool that will confirm that repair.

Even an Ipod is more complex than a meter. Meter is a fancy
electronic tool - therefore it must be complex? That is a usual
response. But a meter is *so complex* as to be sold even in K-
mart. A $20 ($10 on sale) tool also sold in Lowes, Tru-Value
Hardware, Walmart, Sears, Radio Shack, Home Depot, etc. The meter
reports so much AND means that further information can be provided in
replies.

Even shotgunning works better if we know what direction a noise came
from - which direction to shoot. Just another reason for collecting
facts long before replacing any parts. Currently, we have made zero
progress in solving your problem. Get the meter and review those URLs
in the first post.
