At least, I can't view without registering myself or installing a download manager. So no help for that video.
I'd do a good internal cleaning of such an old laptop. If that doesn't help it probably isn't worth the repair anymore.
I have a laptop Acer 2920 and have used it since 2008. The longest hours using it was 10 hours without a battery. Recently, a couple of problems hit my laptop from a sudden reboot, screen suddenly stop/freeze, and the worst one is this http://www.4shared.com/file/xICVyLLA/troubleshoot1.html.
I don't know what that is so I uploaded a video. Anyone please let me know what kind of troubleshooting I have now.
