For a while now, when I am on the internet for awhile, suddenly my computer powers off, not to a blue screen of death, but a black powered off screen.
After waiting a few minutes, I am able to turn it back on, of course I have lost my homepage and have to reset it, but it's a hassle I guess I can live with.
It happened to me twice tonight (Fri), and I went thru the repower on, but I have my ZA antivirus scan for Fri at 8pm, and wouldn't you know it, I haven't had any shutdown problems while ZA has been scanning.....so I got to thinking, maybe there is some setting in my ZA (I have Internet Security) that conflicts with my sites and as a result the default is to shut down my computer. While the scan is going, I am having no problems, but when the scan is done, all bets are off.
Sites that I go to when this happens usually is Yahoo sports, or any message board like this one.
