You are having a lot of issues with your computer? From what I am hearing the issue sounds like its the computer and not just your web browsers. Generally its very hard to crash modern versions of Windows completely just by having a bad application running. If your whole system is taken down because of Chrome, Firefox isn't running right and Opera wont run at all I'd try and find out why that is.
Chrome crashes because it's a nasty resource hog. Locking my computer up at 100% CPU usage, freezing Windows files so my computer cannot run correctly.
So, because of this. I'm going to just assume I won't get any real help from the Opera Forums.
Thanks for the attempted help, I guess.
That sounded sarcastic, but I truly didn't mean it that way. At least I got someone to reply...
