For the last weeks I've been suffering a problem with a Windows 7 laptop formatted only 2 months ago. From time to time the system complete freezes for a minute or so, and then it continues working as if nothing had happened. In the meanwhile I can't even move the mouse.

I had the impression that sometimes it happened when watching videos, but now I'm almost sure it has something to do with that. Now, if I open youtube, when I try to play a video I'll se 2 seconds or so, and the computer will freeze for a minute before resuming.

What can I do / what additional tests should I try to detect the problem?

press the CAPS Lock key when you get the freeze and look if the light o the keyboard toggles. –  magicandre1981 Nov 15 '13 at 4:41
    
I tried and it doesn't work until the temporal freezing is over. –  user1314836 Nov 18 '13 at 23:25
    
ok, when the light doesn't toggle it is a hardware issue during that time. check this KB and test all steps from method 3: support.microsoft.com/kb/2028504/en-us#method3 –  magicandre1981 Nov 19 '13 at 4:32
    
1. Overclocking: is it possible that my BIOS doesn't have this option? 2. Check the memory: Windows Memory Check passed. 3. Power supply: no change except that I'm using an electricity adaptor as I'm using my European laptop in the USA. 4. Overheating: sometimes it happens just after turning on the computer. 5. Defaults: I don't know what this refers to... –  user1314836 Nov 21 '13 at 1:19
    
5. go into the BIOS and load the default settings. –  magicandre1981 Nov 21 '13 at 4:33

From time to time the service Windows Search carries out an indexing of your files. Streaming media is a heavy load on the system so if indexing goes on at the same time the freeze you describe is not unusual

Open the Windows Task Manager, go to the tab Services, click on the button Services (lower right hand corner). In the new window that comes up look for Windows Search. Stop or disable the service.

After doing this the computer didn't freeze for a few days but now it's happening all the time again. Not only when I use Youtube or other video/audio. –  user1314836 Nov 18 '13 at 23:24
