Hi.. I have a bought a new PC now and its a assembled one. I have the SEAGATE 250 GB HDD and I have installed Vista Ultimate on it. But what I feel is, its a bit slow. Dont know,why, I already have 4GB RAM (TAMKOR) and IntelDG41RQI Mother board and still its slow. So, I want to install Windows XP SP3 now and keep it as a nice system. So, what should I do now ? Can I just insert the bootable XP DVD and get it right ?? Possible ??
