I need your help. It's been since a couple of weeks by now that my cpu reaches peaks of 100% usage on tasks that, before, never needed this much work. And it is pretty annoying, seeing that when the cpu reaches these peaks, the system starts lagging.
When I talk about these tasks, I refer to something simple, like watching an HD video (doesn't matter if it is 720p or 1080p), surfing the web, watching video on youtube (even though, where it suffers the most is when I try to watch some streaming on Twitch).
I already checked if it was something related to the heat, but the temperature never goes over the 80°C. Also, when I check into the task manager, the process that works the most is the process of the actual application that I'm using (so, if I'm watching Youtube, then the process is chrome.exe, if i'm watching a video the process is vlc.exe and so on).
My System specs is AMD Phenom II x920 x4 2.8ghz (not OC), 8gb ram ddr2 and geforce gtx470, Windows 8.1.
Guys...help! It's so annoying.
