Specs: Windows XP Home, Athlon64 4000+
I have now sorted out my PCI-E 2.0 issue, having discovered that my VIA chipset does not support it. I tried everything from chipset drivers to the latest BIOS and it had no effect, PCI-E 2.0 just wouldn't work. In order to upgrade to a GeForce 9800GT I will need to change my motherboard.

I scratchbuilt the machine two and a half years ago and installed Windows XP Home from an OEM system builder disk I bought. Is it true that if I change the motherboard, Windows will not allow me to reinstall unless the mainboard is identical to the previous one?

In order to maintain similar graphics performance to my old 7900, I need to change the board to something more recent!

You should be able to change the motherboard. The worst case scenario would be the need to perform a repair install.

Your CD is a full version of WinXP with no support from MSoft and usually non from the vendor you bought it from.

While the EULA does state the OS is to be used on one PC only Microsoft has recognized that hardware fails and needs to be replaced.

One thing to mention. If your WinXP CD does not include at least SP1 you probably should perform a slipstream to the files on the CD and burn a new CD. nLite OS can perform that task fairly easily. You can also include any needed SATA controller drivers. If you are presently using a SATA hard drive then you may need to perform a fresh install because the new board will probably require different SATA drivers.

Are you planning on going to something completely new including processor & RAM?

My Windows disk is XP Home OEM with Service Pack 2 and I bought it from I currently have the OS installed on a 160GB Seagate Barracuda IDE HDD.

At the moment I'm not planning on changing anything other than the mobo and VGA card, which why I need to change the mobo. I'm on a limited budget but when I can afford to I will be upgrading to a dual core AMD.

My main concern was that the mobo itself is absolutely fine and hasn't failed.

I think you may be able to do that with minimal trouble. What socket type and RAM type and size are you using currently? Are you located in the USA?

It's a socket AM2 board and I fully understand that PCI-E 2.0 is compatible with PCI-e 1.x. It's just the the chipset ASUS used on my board is incompatible and does not support it.

Having done some more research, it seems that some of ASUS's early AM2 boards used an older VIA chipset that isn't fully compatible. Interestingly, I can't seem to find any AM2/AM2+ motherboards that still use VIA chipsets, they're all either AMD or nvidia based. It was one of the first boards with a VIA chipset that supported AM2.
