andy2510,
Wow, so it is, I thought all of you above were on Intel as well! (I'm on an Intel Pentium D 3.00GHz myself... left AMD at the Sempron stage but that's by the by). Interesting that we all share the same Southbridge but it makes sense seeing as that controls the PCI/PCI-E/AGP slots. Also, previously I was getting BOTH a "VIA PCI-to-PCI Bridge and a "PCI Standard PCI-to-PCI Bridge" reinstalling on startup, but by reinstalling Vista and using the latest Hyperion drivers (NOT installing them though) and pointing "Update drivers for this device" towards it, I got the "PCI Standard..." bridge to reinstall, correctly, as a "VIA PCI-to-PCIE Bridge", though it still repeats at startup. Somewhat a step forward!
Also, I've been doing some digging. This problem is on many different forums including ASUS' own forum! Here's a collection of links which refer to it-
