Is there any way to assign more memory to a video card?

or



do i have to buy a new card compleatly?



(also i have googled this and people have sayd somthing about BIOS, if so then how do i get into the BIOS?)|||Assigning your physical memory to your graphics card will result a shortage of your total system memory and your whole system will slow down a bit.

Video cards meant for better processing the graphical content of your system and free up your system's physical memory.

So, if you buy a new and better video card with more memory you will have a fast system with better performance.|||You can only do that with onboard video cards. If you have an onboard you can choose how much ram to assign to it in your bios settings. However it is limited and if you already have 128 assigned to it, that's probably about all it's gonna give ya. But hey it never hurts to check.
