yea he built me the computer and told me that I couldn't have windows xp because it wouldnt beable to use more then 3.5 gigs of ram and that any vista will! and I beleived him because when I went into the computer and under system it shows the 8 gigs.. however I went into task manager and it shows that 1.09 is being used and that was like 3 outa the 10 bars.. thats why I ask! I'll go down there tomorow and I really hope he exchanges it! yea i got it for 90 bucks but still I want my 8 gigs of ram :| I paid alot for it!
