whether this helps or not...here is a short story and a suggestion.
Years ago in 2003 (I still own this system btw) I had an FIC VA-503+ Motherboard. It has an AMD K-7 500Mhz type processor.
I started out with an 8Mb PCI card, it didn't run graphic intensive programs very well.
I got by with a Voodoo3 2000 16Mb PCI video card, but that even had slow graphics.
Any way when I tried installing a 64 Mb ATI Radeon 7000 video card and attempted to boot the system, it would not get past the Windows 98 splash screen before it rebooted over and over again, till I shut it down.
Nothing I did fixed this problem, until I got brave and flashed my motherboard's BIOS rom.
Once I had flashed it with F2A5LEF09 Bios, I tried buying that video card again and to my amazement, the post went into windows, where I was even able to install the catalyst software and drivers.
The card still works in that old relic (LOL)
I was also able to upgrade my AMD K-7 233Mhz processor to a AMD K-7 500 Mhz Processor after flashing the BIOS.
The point I'm trying to make here is, if there are no defective hardware issues, perhaps you need to flash your motherboards BIOS chip to a newer version, that supports newer hardware.
Go to your motherboard's web site and see if there is newer firmware available and check to see what the BIOS update revisions offer....they might actually add newer hardware support or bug fixes.
(EDIT): I also suggest going to your motherboard's chipset driver web site and downloading and installing the newest and latest chipset drivers.
Hope my two cents worth helps you divpreet
