whys my laptop getting lag when my internet connection is slow. My laptop is a high end gaming so it shouldnt be doing that, when i open 1 browser(google chrome)?

What type of net connection do you have.

Just because you have a high end rig, it can only operate online connections at your connection speed. Factor in internet traffic, time of day, and other factors and that could explain why you are getting lag.

I have a 12Mb connection, a high end rig and depending on time of day I get internet lag.

It also helps to clear your browser cache once a week and keep your rig clean by blowing out the dust. Especially on your CPU and GPU heatsinks and fans.
