Well one of my friend's computers starts up real slowly.. you know the WinXP logo screen and the blue lines that go from left to right, it goes across over 30 times, so it's a long load. I did almost everything, spyware removal, disk defrag, optimizing the registry, using system mechanic pro, looking at any services he doesn't need, bootvis... what is there left to do? His system is fast, so specs shouldn't be a problem. (Meanwhile once he gets on windows, his system is really fast since all those optimizations i did).
