I have a home built PC with a 900 MHz KT7/KT7-RAID mother board in it. After years of faithful service it appears to have failed. A couple of weeks ago when I booted the PC up it gave Windows 2000 active desktop errors. I cycled active desktop off and all was well. This happened on the next couple of reboots. On the next boot up everything looked normal until the Win 2000 splash screen with the progress meter came up. The bar gets about half way across and stops, never to move again. Booting in safe mode gives a blue screen asking if there were any software or hardware changes. There were not. I ran commercial hardware diagnostic software and it finds bad serial and parallel ports, but the mother board checks good. I pulled every card from the PC and swapped the video card out with a know good one, same results. I have two extra hard drives not installed but configured like the drive in the PC. I get the same results booting with each one. At this point I'm 99% sure the mother board is the culprit. I'd be happy to listen to any troubleshooting steps I may have missed. In the absence of that, can anyone tell me where I can find one of these boards with 900 MHz processor for a reasonable price. If not I'd be happy to get suggestions of replacement processor board combo recommendations in the 3 GB range. I'm trying to decide whether buying a PC or upgrading this one is my best bet. Thanks SGF
