Actually the problems I've encountered ARE caused by the DriverPacks. Here is how I tested. Used a New WindowsXP CD with Integrated Service Pack 2. Ran the latest packs (v5.10.1base, and all the latest packs). Installed this new CD on 4 different machines (two Intel - 955 and an older 875p ) and (two nVidia - Abit NF2 and Asus NF3), using both Method 1 and Method 2. On all 8 tests, all 4 using the NForce chipsets encountered the problems I've described. So it appears whatever drivers and/or changes you've made to the nForce drivers from the 5.07 builds to new v5.10.1 is what is causing the problems. As I said before, there are no changes to the DriverPacks BASE, except for the URI's. Do you use RyanVM's UpdatePacks? P.S.: on my ASUS A7N8X-E Deluxe the nForce 2 chipset drivers installed without a hitch. But I admit, that was with DPs BASE V5.08.1 - though there is virtually no difference between V5.08.1 and V5.10.1, as I've already said numerous times.
