If you want good help, go to GS aka Nigel's shop. Pc cares and solution #02-32 if i never remember wrongly. That guy trying to scam you more money. You are on a 8 year old cpu + motherboard that he supposingly upgraded for $700. All he did was install windows 7 + add more ram. Doesn't even cost him $200
