Procedures after replacing cpu

[Harry Putnam]

I managed to mangle the many pins on the bottom side of the cpu while
tinkering awkwardly with the machines hardware.

It's a P4 3.2ghz. - P4C800-DE mobo - Was running windows XP pro

I actually managed to snap several of fine little pins clear off while
attempting to straighten them.

I found a replacement on ebay and will be installing it soon. But it
finally worked it's way into my peabrain that I would no doubt have to
completely re-install the OS from scratch.

A few things occurred to me that might be stumbling blocks.

Will I have a problem from microsoft getting the re-install activated?
(I do own the disk and serial number) But actually have 2 purchased
disks with different serial numbers... and am not sure which was
installed on that machine... One disk is from back before s/p 2 the
other includes s/p 2.

I'm not sure now which was on there.

Also, I wondered if it might be a lot easier to restore an image made
with ghost?

The image is of a different machine with somewhat different hardware
that is also running Windows XP pro. and has sp/3 installed.

Seems like I could work out the hardware differences just by
installing what ever is different. (I do have or can get the drivers
and whatever)
and uninstalling anything that isn't actually on the machine, through
the hardware manager.

But again, will I run into problems authenticating the OS with
microsoft?

And finally, I've never done a cpu replacement so not really sure what
all is involved after the replacement in terms of getting an OS
installed and in running order.

Maybe someone who has done such a replacement might supply a brief
outline of what need to happen?

Why? If you are ONLY replacing the CPU (microprocessor) itself with an
identical unit, that shouldn't be an issue. OTOH, if you were replacing
the motherboard, THAT would be a different story.

After you get the new CPU, unplug the computer and open it up to get access
to CPU and Heat Fan assembly on the motherboard. Then *carefully* remove
and replace them. You can find some good articles on replacing the CPU and
fan assembly with Google.

There are actually pins on a processor, that can be snapped off
without any consequences. You should download a datasheet for
the original processor, and find names for the snapped pins.
If they're core power and ground pins, there are many of
those, and a few missing won't affect it. It depends on
your luck, as to whether you've snapped an important signal
pin, or just a power pin.

In this diagram, snapping a Dxx (data bus) pin would be deadly.
But snapping off a couple VCCCORE might not hurt anything.

There was a guy who used to put back snapped off pins, but
he isn't in the business any longer. He repaired motherboards
(recapped them), and repairing processor pins was another
service he offered.

"recapped" them ? ...do you mean replaced leaked/failed capacitors ? I
bet he had to use the existing capacitors "tails" because, I think, that
during assembly they're actually "punched" before floating on the solder
bath ?!?!?

Anyhow, I recently fitted a new motherboard and cpu into, and rearranged the
innards of, 2nd PC, ...and whilst spending several happy hours :-( wading
through just what's on the boards, back panel layout etc. I plumped for an
Asus M3N78 which had almost all solid aluminium polymer capacitors but,
annoyingly also has several of the older type that can leak !
The M3N78-PRO has ALL solid capacitors but, there are no D-SUB or DVI
monitor ports - just one HDMI port - ....having said that - I don't think
there is an onboard gpu chip - so now I realise that I should have gone for
the PRO version to get all solid caps. because I would have had to have
bought a graphics card for it anyway !

Oh, the joys of wading through just what's on a board, ...eventually one
gets fed up, and chooses one with an element of hope !! ...and despite all
my wading I didn't spot that SATA ports 5&6 could only be used for AHCI or
RAID (non IDE) !! Still, a pci card with 2 SATA ports'll solve that one.

Probably not.

An OS reinstall is to account for changed - meaning DIFFERENT - hardware,
such as a different drive controller.

You will be replacing with essentially an exact duplicate. No reinstall
should be required, at least not for that reason.

What if the mobo stays the same but you put in a different CPU. I had a Core 2 Duo 7400 and somehow zapped it. SO i went ahead and used that as an excuse to go ahead and pick up a quad core 2.5ghz Will this cause a problem with windows 7? Because ever since i put it in and have been using the PC its been getting several blue screens and it locks up sometimes. The performance is very under par. For example, i was at one of those streaming video sites and i could not net one video to play that wasent jerky or had issues. I was thinking before the CPU fried that it was my Video card. I think it has been a gonner since i bought the POS.7100 series. Any way let me know if you have any ideas. I have posted my computer summary from Everest Ultimate.

Take Care,

Michael.

Re: Procedures after replacing cpu


<snip>

If you simply replace the CPU

your OS will never know the difference...so don;t worry about it.

OTOH: If you replace the mobo with one of a different type...
then you will probably have to perform a repair install

Take Care,

Michael.

E7400 was a 2.8GHz processor. Q9300 is a 2.5GHz processor.
Quad core only helps, if the application is multi-threaded,
like perhaps Photoshop would be. Other applications would
be using a single 2.5GHz core.

Q9300 is not in the CPU support chart ? I don't think this
is particularly serious, but it is something you'd normally
check before buying a new CPU.

http://www.biostar.com.tw/app/en/mb/cpu_support.php?S_ID=312

Did you look at the Device Manager "Computer" entry ? Does it
say something like "ACPI Multiprocessor PC" ?

Have you used a utility like CPUZ (cpuid.com) to verify the
instantaneous clock frequency ? It should read 2.5GHz when
the processor is being kept busy, and run a bit slower than that,
when the desktop is idle. You can run it while the following test
is running.

To do a quick test of the qualities of the hardware right now,
you could run Prime95 stress test (mersenne.org/freesoft). That
is a multi-threaded application. On a quad core, it should start
four test threads. I let it run for up to four hours, and no
errors are acceptable. If you see an error cause one or more of the
threads to stop, then you have some hardware tuning to do. It could
be some bad RAM for example.

You've probably had the 2x2GB of RAM installed, for both the
7400 and the 9300, so I guess we can't blame the RAM configuration.
You could try running with just one of the memory sticks present,
and see if the symptoms change at all. (Remember to turn off all
power, before changing the RAM configuration.)

Also, I think you should say a bit more about how you "zapped" the
7400. Did you take it out of its socket at some point ? Perhaps,
when you explain what happened, it will become apparent what
other hardware in the computer got stressed. Maybe the motherboard
itself is damaged.

Michael.

Streaming video sites are unreliable indicators of performance, the
performance problems could be just network-related. Now, if you
completely download a streaming video and save it to your hard disk and
then play it, and it's still jerky, then you have a problem.

As for your BSOD issue, you'll have to turn on your mini-kernel dumps
feature and analyse the files that come out of them. That's the only way
you'll know what is causing those BSODs.

Is it possible that whatever fried your previous CPU, may have fried
your memory too? One way to tell is to run Memtest86+ on your machine.
However, I'd first turn on the mini-kernel dumps and see if the BSODs
might be memory related.
