right click my computer, click properties, then click device manager. We want to see your display driver, processor and RAM. Click the + next to all of those, and what you've got should come up. Every PC has a processor, so there's no way that's "N/A". The graphics card may mean you have integrated/onboard graphics.

I have Vista.
Memory: 894mb ram

There's your problem.

I suppose it is, thought I had a laptop with 512 RAM and vista, and never had any lag (even though 1 gig is the MINIMUM).
