Changing the number of processors to speed up boot times is a fallacy. If you changed the number, you were wrong to do so.
As for the mouse showing briefly, my GFs lappy does the same thing and it's good as gold, i think it may have something to do with the graphics card???
msconfig entries can nearly always all be disabled. Things that you can live with starting manually, do so. I'm sure you don't use your 360 accessories every time you turn on your PC, so, turn it off......you get the picture
I think you should change the title of the thread, to "abnormally quick
boot up time"
Also, what's with the 2 scroll bars?????? Now that's abnormal!
