Ok I think it works now. Thanks Kirock!
Ok, I'm having a similar issue with a PCV-RX741 (Sony VAIO dekstop) with the SiS 740 integrated graphics. I would like to upgrade the graphics with a PCI graphics card, and I'm currently researching to see if its possible.
The next trick seems to be getting the computer to recognize the PCI graphics card as the primary video source. For some people it seems that disabling or uninstalling the SiS graphics drivers/hardware in Hardware Manager is sufficient to get Windows to use the PCI card as the primary, but for others it seems this doesn't work and they then hunt through the BIOS trying to turn off the Integrated card, but are unable to do so. One person said there were options for the amount of memory to allocate to the integrated graphics (16,32,64 or something), but not an on/off option.
Was the proper installation of the new graphics card drivers (after the uninstallation of everything associated with the SiS graphics) all that you needed? Or were you able to toggle a BIOS setting or something?
Which steps in Kirocks 8 fold path a few posts back worked for you?
The only other thing that I saw online was someone mentioned that which PCI slot is used for the new graphics card might affect things due to some kind of conflict on the BIOS level (over my head...). They seemed to think the top slot would have the best chance of working because of some kind of shared resources between the top PCI slot and the integrated graphics. Anyway...out of curiosity...which slot did you get it to work in?
Any feedback would be greatly appreciated! This thread is a testament to the awesomeness of online tech support!
