I think that your hardware is outdated....upgrade you're CPU....celeron 1.7ghz..i have that in my old dell..slow as hell.
graphics card, yes update..thats an integrated card isnt it? DEF. upgrade even if it isnt. thats such an old one.
maybe ram...like 512mb more would be nice. and the harddrive is fine...
edit/ thinking about it. that whole system is OUT dated...just try to scrounge up enough $$ for a new one. ...maybe i missed it, but what brand is your comp? HP? Dell?
