You can buy a replacement Dimension 9200 motherboard from HERE

Actually you should be able to use any BTX motherboard.  You might want to look around at what features you want and what deals you can get.  Ebay and Amazon have some other BTX boards.

That is not correct, both the Dimension 9200 motherboard and case have proprietary features, plus if a non-Dell motherboard is used, a new retail, or OEM copy of windows will be required, as Dell's OEM copies are tied to their BIOS and will not activate.

Hi

I live in the UK - I did get it working but I am getting lines across the monitor from the Dell boot up screen all the way to the desktop.

I have put a new graphics card in which was working fine but the lines have come back - does anyone know what this might be or how

to solve the problem.  Could it be the mother board??

You could try a couple of things to narrow down the possibilities.  Try your computer on a different monitor also try a different screen refresh rate on your monitor.  Make sure your graphics card is completely inserted in its slot.
