pc lag

[aman]

if laptop has cd/dvd drive then
cd/dvd with live linux versions should be available in the local market
[where computer parts & peripherals are available] at nominal price.
secondhand books shops (esp. weekend market) might also have such Disks

 if i use cd/dvd then my windows 7 will stay on my computer but whenever use dvd then linux will play like an app and after shutdown, windows 7 will restart, right, will it consume my resources unncessarily or just will be better
