Format Laptop =.="

owh....its been a while im limiting myself for blogging. well, lappy neh buat hal plak hari 2. before neh ok ja. so by hook or by crook, kena la hantar lappy neh format. one thing yg i hate about formatting laptop is bila dh dpt blk lappy 2, i don't feel that it was my lappy. everything had changed! wawawawa.....shiro3x....! i hate when my lappy is out of my control. suma benda dh lain even my lappy dh di back up kn. i still missed my old lappy. pastu lak rasa mcm nak delete ja benda yg deorg back up kn sbb everything is useless. contoh nya skype; i need to download it back since it been direct install from the internet.ym pn sama.paling sakit hati, my cs2 adobe photoshop pn deorg dh musnahkan.igt deorg nk install balik ke kalau x pn install yg baru ke. i beli original cd to x???*eh jap2, yeke? tp still cd 2 dh hilang T__T*. can anyone tell me, back up 2 sebenarnya mcm mana and untuk apa? well, actually my lappy penah di format twice since i bought it in 2008. so, i totally out bab2 format laptop neh. one more thing, kalau folder yang di back up 2 kita delete ok x? ka de effect system de? coz, kt dalam compartment [C:] bukan ke dh ada application data and program file?
