I had a problem. I just got myself a new Computer, OS is windows XP. Processor is Core 2 Duo E8500 3.16GHz I realized that after reinstalling my stuff (like firefox, gigaget, AVG, etc) and have transfered all my stuff from external hard disk to my current hard disk, I bound to see arrow on my right hand corner of my monitor (the place where AVG appear) moving. (I am not sure if before the installation it is happening, it really takes a good eye to notice, it just happen too fast). It seems to move for an icon to appear and a pop sound can be heard (when your download is complete you hear the sound), and i cant see the icon clearly, as it returns to normal too fast, around 0.2seconds. I checked my Windows security center one day and found that when the pop sound is heard and as well as the mysterious icon appearing, my Windows firewall, automatic updates as well as virus protection all turned off for about 0.2seconds. Its fast, and the time it happens is randomly. After the 0.2 seconds, all of them turn on again. I later changed my Windows security alert to (ALWAYS HIDE) and i will not be able to hear the pop sound, however, the problem still exists. All of them will be turn off for 0.2 seconds when i tried an experiment like staring at my monitor for minutes. Sometimes it appear 30 seconds after the 1st and some minutes. I need desperate help, is there something going on in my new PC?
