You have used 1 program out of 10 recommended?
The HD gives a little buzz usually when it freezes.
Have you tested the Hard Disk Drive using diagnostic software?
I just built the system last week so everything is fresh even the HD.
Has it done so from start? If yes, you should reformat the entire HDD and reinstall Windows to see if the problem persists. If it does, chances are high that it is hardware related. Unless you do not take proper security measures such as a firewall, virus scanner and spyware scanner before connecting to the Internet.
