hd2000

I am using Palit 8400GS 512MB GPu for around a year but now I am facing this problem. ON boot The Monitor displays just lines and lines and nothing else. The Intel HD2000 VGA port works fine though for the time being. What can be the cause?

Hi. I currently use i3 2100's IGP: HD2000 for gaming. I want to know which is the cheapest graphic card that is substantially faster the HD2000. Please provide both Nvidia and AMD card. And yes, I do not intend to purchase any card as of now.
