Very simple just remove it from the slot it is in.
No, they are not the same thing.
Well, you can just replace the graphics card with a 512mb card or a higher one.
You will still be able to use the on-board VGA but your new graphics card (depending on which one) will be better so you can use the ports on the graphics cards instead.
An integrated video card is located on the motherboard itself and cannot be replaced. You can add a graphics card to one of the motherboard's slots though. It will then take over and the onboard graphics will not be used. To avoid any conflicts, you should disable the onboard graphics when adding a dedicated graphics card.
Not usually. Video card memory generally consists of ROM chips soldered directly to the card, so if the graphics card goes bad, it's best to replace it.
Replace the video card.
yes, but you'd have to replace the motherboard as well since it's integrated into it.
Replace the graphics card, or get an external graphics card.
If you mean you want to use a graphic card and not your onboard graphics , then yes. But you don't touch the chip, when you install a card into the slot, and remove your onboard graphic drivers, then install your card drivers, then you will be using the card. Most cards will tell you how to install the card and when to uninstall drivers and when to install them. Almost all motherboards have a slot that can run a graphics card. Just make sure its better than your onboard or you will be wasting your time.
The Intel 82945G Express Chipset Family is an integrated graphics solution and does not have a dedicated graphics card to replace it directly. However, you can upgrade to a dedicated graphics card that is compatible with your motherboard, provided it has a PCIe slot. Options like the NVIDIA GeForce GTX 1650 or AMD Radeon RX 550 are good entry-level choices that can significantly improve performance for gaming and graphic-intensive tasks. Always ensure your power supply and system specifications can support the new graphics card.
The computer can be used to find the MB of the graphics card. The graphic card is usually mounted on the graphics card reader. The MB of the graphic card can be read by looking at the drive of the graphics card.
You should go to a expert for that. I strongly do not recommend taking apart your laptop
