Weird Slow Startup / Bootup

the startup is VERY VERY slow. After the Welcome Screen, it shows your desktop and then you gain control and do whatever you want right? Well that's the part my PC lags or slows down a lot. I think the part it lags is when it's loading the icons on my taskbar, like the icons on the bottom right hand screen. I don't have a lot of icons, and they're not resource usage intensive AT ALL. My PC lags during that loading part for about 3 mins or more, and i can't do anything or else it'll make it lag more, i.e i can't open programs or games, i can't even open folders and even if i try to, it takes forever to show up.

The lagging part only shows everytime during startup, but after that it's all good, i can play hardcore games like Crysis etc on maxed setting and do multi-tasks, but i just don't get why it lags so much on startup. In fact, on my crappy Toshiba laptop, it's loads way way WAAAAY faster than my PC, but my PC is way better so i don't understand why. And they both have the same programs and settings, in fact my laptop has way more stuff running on startup and my PC has nothing but games, it's a full on gaming PC only with nothing else, so it shouldn't even lag..............
