Oh, that's a very easy fix. You don't need to send it off to get formatted! haha
Your video card driver got corrupted somehow, and that's causing the jerky scrolling. Go into Device Manager and right click on your video card driver and click uninstall. Then hit the refresh button and install new drivers from the cd or internet.
I'm not sure how computer literate you are, so if those directions are too vague let me know and I'll be more specific (with screen shots if needed).
What video card do you have? Go into display and over to settings, it should tell you what card you have. Then you can download the latest from their website. Not sure why standby doesnt work though, maybe the drivers will help that too.
