I've been running this instance of arch for about 2 years.
I'm having a problem browsing the internet. Whenever I'm browsing my system suddenly starts freezing, it starts with the mouse getting slow.
It takes about 5 seconds to go from "starting to freeze" to "fully freezed". If I'm quick enough, I can switch to an terminal and "killall firefox" or "killall chrome" and everything goes right back to normal.
Most of the time I'm not quick enough and my only solution is to reboot(can't switch ttys, can't move mouse, can't anything).
Where should I start looking to find out who is causing this?
