I've been getting a not responding msg that has been appearing in my browsers randomly where i have to wait 5-10 secs because the browser freezes. I started to get the msg appearing in my outlook. After much frustration on not being able to resolve dispite virus/malware scans showing nothing and trying some suggestions online I did a complete wipe and reinstalled windows 7. I have only installed office chrome firefox and getting thesame issue!!!! but it is not happening nearly as oftern. This leads me to believe it could be a hardware issue?...could it be hard drive?. My pc runs fairly warm but the cpu test shows 46-50 after checking 4 hrs of run time. What tests can I run to finally isolate this issue??
