Might work to install the SW for the video card.
Reboot and disable the integrated graphics...save and exit.
Turn off and UPLUG PC.
Install new card. Replug AC power.
Restart PC....will it run...probably but I wouldn't waste much time getting a higher wattage quality PSU. Always better to have 'reserve power than have too little...450W is where I'd start and don't skimp ...get a good PSU.
I have a Gateway 702GE Desktop PC that I purchased back in Nov. 2004. It has an integrated graphics adapter called Intel 82915G/GV/910GL Express Chipset Family and I also see a tab in my DISPLAY Advanced Settings called "Intel Graphics Media Accelerator Driver". Do I need to uninstall the Drivers for the Graphics Media Accelerator BEFORE I install the new graphics card (3D Fuzion NVIDIA 7300GS-256MB)?? Do I have to do anything with the integrated adapter before I install the new graphics card ?? I was reading somewhere that it is recommended that you update all drivers for the motherboard and the adapter before installing a new graphics card, but is this a necessity?
One last question -- I just noticed that the new graphics card recommends a 350W power supply, but my PC only has a 300W......will the new card even run? There is no separate power supply attachment for this new card, so I'm guessing it is going to pull a lot of my system power when it is connected. Will this slow down the rest of my PC applications and operations?
Sorry for the dumb questions --- any help would be greatly appreciated though...
