[i]Realtek ALC658 Audio AC'97 Codec[/i]
First problem is the AC97 Sound as XP doesn't support this Device. Windows will BSOD out with this and cause several problems that even the newest Driver will not address. I got that straight from M$ today after I had one crash consistently.
Seems that attempting to install the AC97 driver with some of the newest Patches applied causes problems. Not sure which one yet as I haven't as yet tracked down the offending patch. But if the AC97 Driver is ion stalled prior to the Patch it works well at least my ND does without a problem.
Motherboard GA-K8NNXP Specs
The model is wrong probably a Typo as Gigabyte M"Boards are labeled GA-8 not GA-K8 not an issue though. AS the Gigabyte Web Site isn't currently loading I'm not sure exactly which model but it's not really important.
Firewire 400 & 800 on this motherboard
Could be a coincidence but the computer that I was having problems with earlier today had a Plug In Firewire Card. I first noticed that some USB Ports where not working and then when I plugged in speakers the sound wasn't working. When I attempted to add the Realtek Driver the system BSOD out.
Now for testing the Hardware use the Ultimate Boot CD to test the Hardware this runs off the CD and boots directly from the CD so the current OS is not impacted in any way at all and it's free here

Run the RAM and CPU tests and see if there are any Failures. If there are post back with the error report if you don't understand it.
You can also test the HDD with the Seatools Testing Utility or one of the others loaded with the Ultimate Boot CD so you can test all your Hardware.
After you test everything post back with any error results.
