What config do you have, mainboard name and model, processors(both sempron and athon), memory modules, and the rest of the hardware?
What are the BIOS settings?
Was your Windows installed on the AthlonXP before you put the Sempron?
If yes, what tweaking utils do you have installed?

Ok my mobo is the asus a78nx-x,1 gig of corsair ddr400 ram,leadtek 6800agp,80 gig maxtor hd, cheap dvd-rom drive. Yes i installed windows on my xp before i put the sempron in.

You need to reinstall Windows XP using your Sempron & Asus mobo installed. I believe Windows XP does a hardware id check before it loads. If the hardware ids are not the same or similar Windows XP will not boot.

It's a security feature, so if someone just steals the hard drive and uses it as the primary drive in another PC that person will not be able to boot up and read your data. But that security is easy to get around by simply installing it as a slave drive so that person can read your data.

the info is not helpfull:
Motherboard: name, model, chipset
Processors: name, model, speed, core codename, revision, fsb, freqfency, cache, voltage
memory: name, model, speed, latencies, voltage
the rest is not so important.
I think the same, that reinstalling a fresh copy of Windows will solve the problem, but if you tell me the info I need to know I might help you make your WindowsXP run without reinstalling

This information is only partially correct.

Windows checks the hardware as it boots - TRUE
Windows refused to boot if the hardware is different - FALSE

Windows will ask you to reactivate your copy of Windows if it feels your hardware has changed significantly. At most you'll just have to connect to the Internet. However, in some cases you will have to call a 1-800 number and talk to someone in India. This person will give you a ridiculously long code to put into your computer to re-activate Windows.

I still recommend a fresh install of Windows. Also, make sure your Sempy isn't too hot.

Are you replacing a barton 3200+ with a sempy??

Good luck.

PS - If it doesn't work out you can wait for a Conroe!

You're all wrong. He should actually get a blue screen if he just switched out the mobo and chip. The reason is that XP uses a kernel that records what IDE and HAL you have. If you try to boot with a differnet IDE or HAL, it will never start up. It's probably defaulted to reboot on blue screen, WHat you need to do is start an inplace upgrade with the old gear. Then before txtmode setup replace the gear and let setup finish. This is the official Windows method of replacing a mobo or changing IDE or HAL.

I seriously doubt that it is a security feature. More like a way for microsoft to keep you from using xp on multiple computers

He didn't replace the motherboard.

The board is an a7n8x-x...not an a78nx-x... but anyway :wink:

There shouldn't be any need at all to reinstall. I have a half dozen of those boards in one flavor or another and I have switched processors so many times your head would spin. I'd be shocked if the OS needed to be reinstalled. That doesn't help much since I've not suggested anything to fix it, so I will. Put in the sempron and go into the bios and see if everything is set correctly. Might also just want to reset the bios if you haven't already done so.

No, he is not wrong. The only thing changed is the CPU.
And I think that the BIOS settings might be wrong for the Sempron.
There are 2 models of Barton 3200+, the 2.2GHZ (11x200) and the 2.33GHz (14x166).
All the Semprons s462 have 166MHz FSB, but the 3000+ (10x200) which has 200MHz FSB and is with the Barton Core.
If he had the 3200+ with FSB 200, and tried to put Sempron with FSB 166, that results with overclocking and unstability, so Windows XP is not starting.
If hes mainboard is not detecting the mutliplier automaticly, and hes Sempron have both-way unlocked multiplier, there is the posibility of overcloking via the multiplier, and again unstability.
So, we need hes BIOS settings and processor info in order to tell him how to fix the problem

Baron, I still do not agree with you. However, your computer is much better than mine, so you must be right!

I think all you guys are forgetting one thing.

dvdpiddy, have you updated the bios on that mobo? the A7N8X-X was made for the athlon xp. It won't work with a sempron unless you update the bios

Ok back guys. No i did'nt update the bios so that might be one problem but when i boot it it does'nt read as a sempron it reads Amd processor 1500 mhz. Oh and pain yes it was a7n8x-x sorry for the typo guys.

Not true, it may simply not recognize the CPU, but it will certainly work if you set the bios settings correctly for the CPU.

The older semprons for socketA were simply remarked thouroughbred core XP's. The new Semprons as someone said above are barton core XP's, with half the cache disabled...I think they calling that core a thorton or something like that, but anyway.

You can update the bios to see if it will detect it as a sempron, but even if it doesn't you will be able to set it manually and it should work and display unknown processor type.

update bios before install sempron to have the MB to support it.
repair or reinstall your windows with sempron. When changing CPU with other family CPU (as you from XP to sempron) windows will not start as it will not find their marks recognize the install done. Usually in these situations, old HD turn in to a second one (slave) and install a new HD for windows as this is easier than repair or reinstall a windows in a already semi full HD (you have lot of chance to loose all the current data if you press Yes or enter too fast) ... so check these 2 steps...probably you will solve your issues with them...

I would really like to see some proof of that, because I will bet you a paycheck [er, make that a beer, I'm not going to go all crazy :wink: ] that you do NOT have to reload windows to switch processors. There is nothing in the processor that needs to be loaded in windows, no drivers, nothing. I am simply not buying what all you people saying to reload windows are selling.

If I had never worked with these boards before I would keep my mouth shut, but I've got 7 of them. Beyond that, I've never ever ever, not once, ever in my life had to reload windows after doing a CPU switch. It simply doesn't make sense.

Like someone said above, if it's because of the OS authorization, it will boot, you will just need to reauth the OS.

No, if changing out the mobo, I'm right. I did it at Microsoft in the Windows division. If he didn't change the mobo then maybe the BIOS doesn't recognize the Sempron enough to init.

Are you seeing any post? If not maybe the voltage is not high enough. You would think though that Mr.piddy would be able to figure it out as much as he and the other 5 stooges know.

My PC has nothing to do with it. The fact that I worked in Windows might.

Diddy, if a bios update doesn't detect the processor correctly, just set everything manually for that processor and it will work fine.

I have to wonder though, if you have a 3200+ already I'm curious why you want to change it. I doubt the sempron will beat it.

5th stooge, out.

Simple i want to sell my 3200. I got a good offer of 175 from a freind.

You're not one of the 5 stooges I was commenting on. Unless you want to be. What would make you think this was a barb at anyone posting on this thread?
