Hi - My PC sounds like it is under a load even if I am doing nothing. I did a hard boot, then started Outlook and FF - shifted into second gear. It is like I am watching three videos all at one (which I have done, but not right now). I took it apart and did a thorough cleaning - made sure there were no viruses, I use McAfee but I did a free trial of AVG - no help. It sounds like a freight train all the time, unless I turn it off. Any ideas?
