Minecraft: How do you summon multiple items at time (Sand)?

I can summon one sand block no problem. Is it possible to summon more than one?

I got a very very big hole I need to fill. So big it would take me about two weeks fill it with creative mode. Can I summon like 10 blocks at a time other than just one by one with the command?

Computer making some kind of screech noise?

My friend says its some capacitor squeal, I have no idea what that means, basically when I get really high fps in games (around 1000) i hear this noise but when I limit it, it's gone, it does this in minecraft, is this harmful in any way and should there be any reason to fix it? How do you fix it?

Added (1). It sounds EXACTLY like a coil whining video I saw on youtube but I don't know what the means, any help?

After formating my hard drive minecraft won't load?

Hi i'm using my old computer now and before it was laggy. Then i formated the hard drive and installed windows 7. I downloaded minecraft and it says my graphics driver is out dated. But i know it isn't. I've checked time and time again. I'm on a dell dimension e510 running windows 7 home premium. I'm pretty sure it is that i reformated the hard drive because other people on forums have had the same problem as me. If anybody has a fix that would be AMAZING!

Are there any good school/gaming laptops that include my specifications?

I need to find a good all-around laptop for gaming and school. Not necessarily for games that require very high performance but more like minecraft/goat simulator/half life (without terrible amounts of lag) but it also needs a decent battery life, to be good for school work, and to be in the $500-$1000 (a bit higher than that is fine) price range. Any suggestions?
