Try the steps below:
Click on the link below to see if you can load the Flash animation (banner) without the system crashing at:
Don't worry, it's not a video, it shouldn't crash -- if it does, this won't fix your issue. If it works without crashing, right-click on the Flash animation (banner) and uncheck "Enable hardware acceleration" from the Settings panel. You should now be able to view the YouTube videos without crashing the computer.
Hope this helps.
I reinstalled my Windows Vista Home Premium operating system on an Acer desk top with an Athlon 3800 microprocessor. I was able to reinstall all my software including Windows Mail.
When I tried to look at a YouTube video the message prompting me to download Adobe Flash Player 10 or higher appeared so I downloaded it. Flash Player will not work with any website. I uninstalled it and reinstalled to no avail.
Coincidentally I cannot open links in email messages. An error message appears, "Application Not Found".
