I guess this falls under 'Software'

Anyway, the story is this:
I had The Sims (origion version) installed on an old computer, working fine. Then got a new Laptop, running XP Home, tried installing Sims, that worked too.

Then i try actually playing it, and have a huge problem with screen refreshing. There is huge lag, with nothing on the screen properly refreshing, then suddenly looking fine for a split second, before going back to not refreshing.

This just gets annoying as all you can see is trails where people were, or lots of cursor pictures all over the screen.

Any suggestions??
