hi nice tweaks to make pc faster. most of ur tips were known to me and I always follow them. it seems we are similar minded.
a good way to make pc startup in less than 5 seconds.
Instead of shutdown I always use to hibernate my PC and then turn off my ups.
to hybernate click start -> shut down ->when three buttons appear press shift and icon will change to hibernate and click over it .Next time u start ur pc u will get it in the same status such as max/maya oped if u were copying some file it will continue further and so. it is realy great feature. try it and u will never turn off your PC.
I have configured when i press my power button of pc it hybernates insted of shutdown
