Ok, i have a Nvidia 8400 GS, i know this is a way out of date card but everytime i want to open youtube it crashes IE 8+9 (tried both) and restarts it. now it NEVER did this on my old single core processor system but on my new computer it is..
First: Use Internet Explorer to visit www.mozilla.com and download FireFox.
Second: Install FireFox and allow it to become "Default Browser."
Third: Remove shortcut to Internet Explorer.
Fourth: Never use Internet Explorer again.
Fifth: If you continue to have issues, there may actually be a problem. If the problem goes away, it was simply Internet Explorer.
Yeah, that happened to me too. But only when I am watching 720p+ and it did not download yet. 420 and lower is fine. I also have crapy gpu on my laptop. Let it download 100% and it won't crush. As what it is caused by, I have no idea.
