laki ng hd mo...but almost puno na sya. try to back up some files (burn sa cd/dvd) by deleting them. (good candidates are mpegs, mp3, jpegs)

delete temporary internet files: sa i.e. po...go to Tools / Internet Options...may options po dun about deleting these files. it might be taking much space. btw make this a habit: do it as often as you can baka madami na naiipon na files na you don't need.

next: for a pentium 4 2.3 ghz...mababa ang 256mb RAM...if you can afford it..try to upgrade to at least 512mb RAM.

yun lang po ang first aid na naisip ko..hth.

btw: i advice na wag ka magdadala mga cds/dvds na pirated when going out of the country..you never know kung ano mangyayari. better to be safe than sorry tol. my 2-cents po.
