Really sorry for the late reply, but I'm using diagnostic startup because svchost.exe jumps up to 100,000KB on normal startup. That means that I only have 10% RAM left. Also with that much memory used, my computer slows down to a crawl.
Also, using normal startup makes the cpu jump around 30%, sometimes hovering up at 60% for almost 5 minutes. At that time, I cannot open any applications except simple ones like window explorer, though it even takes about 5 seconds. When I use diagnostic startup, on startup, the splashy windows has to flash 5 times = 30 seconds (SLOW) and the logon time takes 35 seconds (I know Terribly slow) In between that time, there is the black screen with movable cursor thing, hovering for 30 seconds. Overall, You could say that my computer is the slowest one in the world.
