My computer freezes on every startup and after restarting 2-3 times. And then it can freeze up at at any random time. I'm pretty sure it's not overheating. I also checked the task manager, my disk and CPU usage was up to 95% most of the time. So I uninstalled a few stuff which I didn't use and I thought the problem was over and my disk usage was down to 1% and CPU to 5 %. But still it goes from 5 % to 60 % Just to start google chrome, when I watch a movie on netflix it can freeze at any random time. Even on login screen I touch nothing and it freezes after 40 seconds.. I need help cause this is very annoying. And also this other problem there comes a popup that wants to activate windows 8 which I already had when I bought my computer. And it appears every 3rd hour It started after I had reinstalled by entire computer. I had bought a computer with Windows 8 already on it and I have no CD or whatsoever. And every second day my computer wants to update. It updates for 20 minutes and then it says. something like "can't configure updates resetting changes" which takes another 2 hours. My computer specs: OS: Microsoft Windows 8 (build 9200), 64-bit CPU: AMD A8-5500 APU with Radeon(tm) HD Graphics 3,2 GHz RAM: 12 GB Graphic card: AMD Radeon HD 7560D Harddrive: 220 GB Note: I don't know so much about computers so be more exact with a retard like me.
