i just got a new computer and i think i find my problem not shure when im in game my fan start going pretty fast and i think it making lag my computer how can i make my fan go slower ?

you mean update them

Use "Gamebooster".

i turn off all the programs with game booster but it still do it im using window xp pro on my computer so its bizzar windows xp not taking that much space in a computer

lol, i normally got 40 fps and i dont lag at all. and the lowest ive seen it is 25 fps and i still dont lag when its 25... if yours is 100 then your ok? try reinstalling crossfire on a partition of your harddrive where you DONT have your windows installed. also if you do not have a partition intall crssfire directly on C:\z8games NOT in C:\program Files\z8games.

and try Iobits ''gamebooster''

also, does it lag while you hack? or does it still lag while u play legit?

it lag when i hack and legit i try what you say put in C:

still does the same thing nobody can help me?

you can try using game booster or defrag ur comp. You an also try to look for virus in ur comp by using antivirus also make more space for ur drive c and d

i got 150 gb of free space and i just check virus nothing defrag and try it same thing
