I have been having trouble starting up windows XP. Everytime i start up XP, it always freezes. I would do something as simple as try to open My Computer, or internet explorer, and it would freeze, or take a lifetime to open. I am also unable to install any programs, as I keep getting Error 1117 I/O error. I have ran HDD tests, and everything points to the HDD being fine. My main suspicion is that I have RAM problems?? I have done 2 complete formats, and fresh installs of windows XP profesional, and that didnt help! Does anyone know what could be the problem?
