About three weeks ago, my laptop started to randomly freeze when using Skype or listening to music on YouTube.
I use Windows 7 Home and all kinds of software.
Yesterday, I reinstalled my OS and got Windows 7 Professional (not upgrade, a clean installation, so no other applications installed) and when I Skype, it still freezes – though less often then normally.
I also tried to install an older version of Skype but the problem persists. Do you think it could be a hardware problem? Since there is no error message after it refreezes after a minute or so. I don't even know how to analyse what goes wrong.
Please ask if you need more info about my laptop.
EDIT: more info a lot for your help. I cleaned the vents but it did not help. Also, today, I reinstalled audio drivers since that might have been the problem, as Rob suggested. Again, without success.
Do you think there might be a problem with the connection to the internet which would actually be able to freez my laptop? What I did to test that: go to youtube and have several videos downloaded to cache. play all the videos at the same time + watch a movie from external hard drive + browse photos from external hard drive = no freezing. VS. open a youtube video and let it play before it all is downloaded to cache => freez.
My connection: university wireless internet connection... maybe I should try to connect to the internet via LAN cable?
Another explanation that I can think of is that I moved from Europe to the US. Do you think that might have an influence? I doubt that...
SOLUTION Ok, after using cable to connect to the internet, the computer did not freeze. So I reinstalled my wireless drivers (Atheros AR9285 drivers) and it seems working!! :) I will keep you posted if it really helped.
