I was having studdering issues in Railroad Tycoon 3, including BSOD crashes in nv_40.dll.
I was also experiencing 0x8E BSOD errors (Audigy Squal of Death) when using teamspeak while playing C&C Yuri's revenge.
It seems a combination of Audigies + Via chips + Nvidia cards have some type of PCI bus flooding issue, which causes these troubles. I've tried tweaking RAM timings, PCI Latency, IRQ's, PCI slots, AGP aperture, I've even tried power strip hardware tweaking software...but no success so far, until i disabled fast writes, and set the pci latency between 64 & 128.
