I have a Windows 8.1 laptop (Intel i5, 6GB RAM, 2GB Nvidia graphics card). I'm using VLC player for playing videos. While playing games or watching videos, there's lag. I don't know why, but when I check the Task Manager, "Windows system service" or something else uses 100% disk, and then everything slows down. It occurs once a minute, maybe this causes the lag. I installed Avast Internet Security antivirus. When I start my laptop, Avast takes 100% disk usage for about one minute and then slows down. Some search results from Google said Windows 8 uses the disk a lot. Is there a way to stop this lag?

Sounds a lot like this issue here (This may be of help).

You're not the only one; this seems to happen to a lot of people. I know that System Updates in the background can run disk I/O up to large levels, as can antivirus scans. Not too sure on the reason for these spikes though; it happens to me quite often too.
