text: my window xp professional does not boot normally.   i have to switch on and off, atleast 5 times.  why? this is happening, since one month although earlier, the window was opening properly, with one switch on.      without altering anything, if i switch off and on nearly 4 or 5 times, at the 5th time, it opens, as normal.                 please let me know, why is this happening.     thanks.....v.r.rao
