So I'm getting these random 10-15 second freezes on my pc (in the Sig) and I don't know where to start. It usually happens when I switch tabs on chrome with one of them running some kind of video on HD. Sometimes it's just Chrome that stalls and then comes back, sometimes it's the whole explorer. CCleaner doesn't help, I defragmented my HDD, nothing changed. Games are running fine. I really don't what I can do about it and I'm not impressed by the idea of re-installing windows and all the things with it. Is there someway to find the problem?
