CPU

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.

Procedures after replacing cpu

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?

If you simply replace the CPU



your OS will never know the difference...so dont 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

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.

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.

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.

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.
