I see you are assigning 3GB RAM to the guest, which is rather a lot for a 32bit VM. I suggest that you try reducing that to 1GB, or 2GB at most.

I have changed ram of guest to 2g, problem still.

Check if you have the latest Video drivers for your graphic card, and install the newest if not. Then see if there is any improvement.
