Hi~

My computer kept crashing until SONY fixed it( changed the harddisk or something) and everything got deleted. i want to start a new fast and good computer which wont let me down that much instead of buying a mac. so im wondering if upgrading from home premium to windows 7 professional would affect my RAM or CPU or anything like that because if not i will have to buy them separately. I heard windows 7 was awesome so i want to try it out.

Additional Info-

- this comp has been with me for two years

-i need it for both work and games :D

-i want it fast like downloads and stuff and you know

Question: what to buy for my comp?

what stuff to buy to increase the speed of my comp? e.g ram and cpu

thnx so much

Details of comp VAIO- VGN-FZ15G

-Windows vista home premium

-Processor - 1.8GH intel core

-1.0g ram
