How many Windows XP users have experienced at least once an unexplainable slowing down of their computer? Maybe too many! What was the solution? Reinstalling the operating system. But in my case, this did not work.
Let me tell you the whole story: one year ago, I noticed that my system started to act very sluggish, even on simple tasks, such as editing a PowerPoint slide, or writing a document in Word. Switching on the computer took me about 3-4 minutes, and no program launched in less than 30 seconds (which in this case is almost an eternity). I reinstalled the system three times, each time everything was OK during maybe the first day or so then the problems appeared again.
Yesterday I installed a TV tuner. Everything went OK with the installation and channels search, but the videos were not smooth, and the sound had interruptions and a lot of noise.
For a computer with 512 Mb RAM, 1.6 GHz processor’s speed and 64Mb video card, this was totally unacceptable, so I started to investigate possible reasons:
After about one hour of Google investigations, I managed to fix the problem for good. This is the chain of events:
This problem annoyed me for so long, and the resolution was so simple, that I wanted to send out a warning for all of you who might experience it: make sure that you have only one security program running, and in case you switch to another product, make sure you remove all traces of the previous one.
