Specs: Windows XP
Upgraded motherboard and processor. Now XP partially loads splash then reboots, continuously.
This may be registry problem caused by going from intel to AMD but how do I fix it? Also hdd works fine when back in old motherboard (after repair install!)
Followed instructions in Microsoft article KB824125, to install new MB...

Assuming there's nothing wrong with your hardware (e.g. if you're using the same power supply it may not have enough capacity to handle the new mboard, etc., especially if it has a PCI-E X 16 video card installed on it - see below).......

If you install 2000 or XP on a hard drive when it is connected to one mboard, then connect the same drive with the same Windows installation on it to another mboard, if the hardware (main chipset, I/O chip, etc.) is more than a little different, 2000 or XP's Windows will NOT load all the way.

That can be fixed if you run a Repair installation procedure from the Windows CD, without you losing the personal settings and data you have added to the partition Windows has been installed on.

See Response 1:


Your power supply must have at least the minumum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD!)
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you're a gamer.....
In most if not all cases, the max capacity rating of the PS is an intermittant rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.

If you need to get a PS with more capacity, you can usually replace it with any decent standard sized standard ATX PS.

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Don't buy an el-cheapo PS.

Had upgraded power supply also... Repair install ends up with XP loading splash screen closing after a few seconds and the computer rebooting continuously...The registry doesn't like going from intel to AMD...
I gave up and did a fresh install on a new drive and then moved my data and apps from old drive.
What happened to the good old days? These are the good old days... Ouch!

"Repair install ends up with XP loading splash screen closing after a few seconds and the computer rebooting continuously...The registry doesn't like going from intel to AMD..."

If you successfully got all the way through the Repair installation prcedure and did NOT get ANY errors reading files from the XP CD, then the registry was CHANGED so that it was compatible with your changed mboard hardware, so it could NOT be " The registry doesn't like going from intel to AMD..."
Running the Repair installation procedure can't fix everything, but it's worth trying - your re-booting loop was caused by something else.
