Computer beeps when 3 keys are pressed

[Danny]

Those things have nothing at all to do with Ctrl+Alt+Delete. My guess is you simply read "starts beeping" and posted from there.

Dan, unless you screwed with computer settings somewhere down the line, you probably have some sort of virus or malfunction. Try doing all the usual things: defrag (couldn't hurt ), virus/crapware scan, etc. Also, if you have CCleaner, use it (and if you don't, get it). After you do all that, shut down your computer for a few seconds and then start it up again. If you can't find any problem and you're positive you altered nothing (and really look), try System Restore. (If you don't have that enabled, then either right-click the taskbar for the Task Manager or, yeah, reinstall your operating system.) You could always wait it out and see if it simply goes away after a bit, too. Windows can sometimes be like that, especially if you've just had the computer for a while.

Scanning, will defrag later if it doesn't find a virus. Thanks for the info

ctrl + shift + esc openes task manager too. In Google you can find a lot information on the topic.

That works OK, thanks. I guess I'll just use that if my problem doesn't go away.
