There's one more slot but when I tried to put it in, it was too close to the PSU. Yeah, I did a safe mode + networking reboot and used DDU to uninstall the driver, and then I installed both.
I went ahead and did a clean install of Windows 7 Home Premium 64bit and I still seem to have this problem. Looks like ataport.sys and USBPORT.sys are the main problems.
