Do I need to reinstall xp?

I am about to upgrade my mobo, cpu, and ram, but I wish to know if I MUST reinstall xp, or can it cope with such an upgrade without a reinstall?

I ask this because I have 40gigs of stuff and i dont want to backup unless i have to.

New Mobo: ASUS A7V333-X
New CPU: AMD XP2500+ 333FSB 512kb L2 Cache
New RAM: Crucial 512Mb PC2700 DDR
LVL 2

You should be fine without reinstalling.  However you will have to install all new drivers, but XP will most likely do all of that for you.  That is one great thing about XP.

I realise that I will have to install drivers. That's to be expected with any hardware upgrade.

But so long as I can continue to use my PC after the upgrade with reinstalling XP, then I will be very happy.

Even if you reinstall, your data should be preserved,, as long as it is not in any of the windows folders.

               http://support.microsoft.com/default.aspx?scid=kb;en-us;Q271965
               "After you move the system (boot) disk to a backup computer, you may receive the following message on your Windows computer when you try to start the backup computer:

               ***STOP: 0x0000007B (0xF741B84C,0xC0000034,0x00000000,0x00000000)

               CAUSE
               The registry entries and drivers for the mass storage controller hardware in the backup computer are not installed in Windows.

               For integrated device electronics (IDE) controllers, there are several different chip sets available, such as Intel, VIA, and Promise. Each chip set uses a different Plug-n-Play (PNP) ID to identify it.

               The PNP-ID information of mass storage controllers for the backup computer must be in the registry prior to startup for Windows to initialize the correct drivers. "

I hope this helps !

YES LOTS OF TIMES.  But back up anyway.

I just did the same thing that you are doing about a month ago with no problems.  I also had two hard drives and two O/S on one hard drive and did not have any problems.
meehangeCommented:
Ditto here,

I just changed from an AMD Athlon system to a P4 setup so EVERYTHING was differenct except the 40GB HDD.
The system woulnt boot after the changeover (I didnt really expect it to) it bluescreened! So I actually ran a repair from the XP CD. This left me in a situation where not only did I have all my data files but most of the installed programs still worked.

One caveat for you though, the system ran a bit choppy after the changeover. I don't think this is an ideal situation and I eventually went out and bought an additional 80GB and have dual booted the system, I only rarely boot into the old install drive I just access the data I need from it. Eventually I will xfer all my data accross and format the drive.

Personally I don't think you get the same performance and reliability from a patched up install of windows like this.

Good luck.

Gerry.

the only thing I would recomend is you do the upgrade one-by-one, so put the RAM in boot up and if all is ok, shut the comp down and then do the next upgrade.

This is good practice because if there is any conflick or hardware that dont work with XP then it will make troubleshooting harder if you were to just upgrade everything at once.

well, i cant do that because my old mobo doesnt support my new cpu and new ram. and the new mobo doesnt support the old cpu and old ram.


this is an upgrade from duron900 pc133 ram to athalon xp2500 barton pc2700 ram.
Dave PuseyIT Support SpecialistAuthor Commented:
The friend who sold me the motherboard said to delete the motherboard components from device manager, then upgrade, and xp should do the rest.

Is this a wise course of action? or can I just do the upgrade without deleteing the old coomponents first?
SysExpertCommented:
It may work, but the in-palce XP reinstall is the best option.

Please read my previous comment for more info !

Well, I dont mind doing a clean install and would like to do one if possible, but I have 48GB of stuff and my other hard drive is only 20GB. Is there any file backup/compression tool that will manage to do that? I try WinRAR but it stop responding after it analised the files.
publicCommented:
Try to get a mobo with the same type ide chip. Then in safe mode delete the old sound and lan drivers, change the display to vga. The faster cpu, or mem are not seen as different by xp. Then boot in normal mode, and install new drivers.
Dave PuseyIT Support SpecialistAuthor Commented:
I'm afraid that I have already purchased the mobo so I cannot change it now. The new mobos IDE chipset is different (the new mobo supports ATA133, the old one doesn't).

Please could people concentrate on the question in my last post...

"Well, I dont mind doing a clean install and would like to do one if possible, but I have 48GB of stuff and my other hard drive is only 20GB. Is there any file backup/compression tool that will manage to do that? I try WinRAR but it stop responding after it analised the files."
leadheadCommented:
Davepusey: You should not have any problems doing the change over however may require you to re-activate after the changeover. This is no big deal if you have a legit copy of XP and you can probably do it over the internet.

You should not have to do a clean install.

Be sure after the boot up to install ALL the drivers from your Motherboard Installation CD.
Then run windows updates to check for updated drivers for your new components.
A lot of times people will install a new Motherboard and don't bother to use the Motherboard software and this is where the poor performance comes from as XP will install Generic or non specific drivers.

If you do have boot problems do a repair from the XP CD and then follow the above.
Let us know how it goes!
Dave PuseyIT Support SpecialistAuthor Commented:
So, "Leadhead", you suggest that I dont bother with a reinstall or refresh, and just boot up straight after I finished the upgrade, and IF i get a boot problem do a repair from the cd.

Also, activation is not a problem, as my Windows XP does not have the activation feature.
leadheadCommented:
Thats what I would do. I have changed quite a few motherboards on systems with XP and Rarely have run into problems.   Good Luck and keep us posted.
Dave PuseyIT Support SpecialistAuthor Commented:
Ok, I will try that.

The parts don't arrive until Thursday (4th Sept 2003) at the earliest, so we shall have to wait for a while before we can find out.

But don't worry, I will keep you all posted.
SysExpertCommented:
Again, if it does not work, the reinstal option is your best bet.

You should only need to backup stuff like favorites and My docs.

Anything in a non-standard windows folder ( folder that you created ) should not be touched, as long as you do not try to do a format.

 I hope this helps !

bdubyaCommented:
Done this many times. No problem. Once your hardware is installed, boot from the Windows XP CD. Skip the first repair console option, setup will look for previous installations of Windows. Select your active Windows installation and select the repair option. Windows setup will run all the way though, when completed you'll have all your new hardware configured, and you'll keep all your Windows settings, shortcuts, favorites, desktop etc., as well as all the contents your hard drive.

Gotta love Windows XP :)
Dave PuseyIT Support SpecialistAuthor Commented:
Cool, will try that.

Hardware will be arriving Friday 5th Sept 2003!

Well, I installed the processor and all the other stuff. And I didnt even need to do a repair so that was great. I gave points to the first person to say that it should be ok without a repair.

However, my mouse doesnt like my KVM switch. If i use it on the switch there is no mouse on either pc. any ideas?
