I don't have a graphic card.?

All computers and laptops have a graphics card. If it didn't you couldn't see anything. The graphics card is what sends the video to your screen. By default they all come with an integrated card that is a part of the motherboard. Unless you buy a better, more expensive card (which would be a dedicated card) then you have an integrated card. If you want a better card then you need to buy one from a store and install it.

I'm sorry, but if you don't have a graphics card in your computer then you wouldn't be able to do anything, and there is also no such program that acts as a graphics card

3-D analyzer works as a virtual graphics card. Configuring it can be a little difficult though.

"I don't have a graphic card." That is impossible.
