Squeezing the Sweet Bejesus Outta Me PC

[mrmod]

I'll do 1 and 2 first .

My startup only has BitTorrent and Avast (thinking of changing to a less hungry AV though) and few others (used to have Steam but removed it). Is there a panel I can remove startup programs from?

And that would be installing hardware. Is installing RAM difficult? (I've never opened up a computer but I understand a bit about IT)

Thanks for the speedy reply btw
