my windows is running very very slow, the mouse is like, moving in steps. i hope you get what i mean. i checked the processes and no unknown thing is running. i have a 2.6 Ghz processor and 1 GB RAM. i think this might be a hardware problem, cos one of my HD is also not being detected. i had formatted the whole computer last week, so thats not the problem either. please help.
thanks
