hi everybody. i didn´t reinstall windows xp in long time and now i´m starting to play games and the system doesn´t like it used to. is there any program that can help me fix and "clean" windows xp without having to do all the process of installing windows again??? i already use ad-aware, spybot, kaspersky anti-virus, diskeeper defragmenter, regsupreme pro, and spy sweeper. i heard that some system optimizers will work, but i don´t know anything of this. thank you in advance!!!!
