"....do I have to disable the current video adapter attached to the motherboard."
If you install a PCI-E X16 video card in the PCI-E X16 slot, the video built into the mboard is automatically disabled, the bios ignores the settings in the bios for the amount of ram that is shared with the onboard, and the ram is no longer shared with the onboard video, and Windows can no longer detect the onboard video adapter.
However, you need to make sure Primary video, or Intialize video first, or similar, is set to PCI-E X16, or similar, in the bios Setup in order for Windows to have the proper info about which type of video adapter it is that you are using, otherwise the enhanced features supported by the specific video drivers you load for the video adapter will not work properly.
Un-install any listings for the onboard video in Control Panel - Classic view - Add or Remove Programs after you have installed the PCI-E X16 card .
If you already have a video card installed in the PCI-E X16 slot, un-install any listings for the for that video card in Control Panel - Classic view - Add or Remove Programs BEFORE you have installed the new PCI-E X16 card .
You have a 300 watt power supply.
Depending on which video chipset is on the PCI-E X 16 card you get, you may need to buy another power supply with more capacity.
Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.
If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.
If you need to get a PS with more capacity, you can usually replace it with any decent quality standard sized standard ATX PS.
Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.
Don't buy an el-cheapo (in quality) PS.
