My PC has been randomly freezing and slowing down doing the most simple tasks, like opening a folder or sending a text file to the recycle bin, browsing Facebook(shock wave flash plug-in also becomes unresponsive from time to time). Sometimes the hole system just becomes unresponsive for minutes.
I thought it was a windows problem, so I formatted the HDD and installed windows. But the annoying behavior persisted even after the fresh install.
