You failed to mention what graphics adapter your system uses. IF you are using the builtin adapter, is it possible to increase the amount of shared ram in the bios?

i don't have GPU. But in windows 7 no problem working well.

For a 3D graphics application like blender you're going to need a GPU. The Core iX chips do have a reasonable on-board graphics capability, but it's not really designed to do serious 3D work. Increasing any settings in an app like Blender will degrade performance.

A dedicated GPU doesn't need to be expensive, even a budget one should improve your situation somewhat.
