Dear all:

I don’t know why my system gets very slow in the first five minutes after i start my computer. My system running windows 8 ultimate 64 bit, and this problem occurs for some time. After my computer just start and I operate any software, the software will have no respond for a while, and then they will back to normal. If I start my computer and wait for at least five minutes, the problem will not happen.
Who can explain why? By the way, I already optimized my startups. Thank you.
