“No Hardware Acceleration” usually means you either:
1.) Have very outdated or even nonexistent drivers for your graphics card
2.) Have a very outdated graphics card, or
3.) Have a distinct lack of anything that could be considered a graphics card
Solve this by:
1.) Updating your graphics card drivers from the manufacturer's website
2.) Buy a new graphics card, or
3.) Buy a graphics card :P
Have you tried repairing your Windows install, or, worse comes to worse, reformatting? If you reformat, you'd need to reinstall all your previous drivers, graphics included.
