This is really a head scratcher.
For the last couple of months while watching videos my XP Pro, SP3 mochine, will just suddenly turn off. In addition the video playback has been choppy and just horrible. I've been using Chrome so I did what was recommended in the forums and made sure I was using just one flash player etc. All drivers are up to date, system is tuned using Advanced System care, etc. etc. etc. This morning however while trying to make a very short, 3 minutes Camtasia video I couldn't get it to render. System will shut down again and again and again.
So I logged in using a different user profile and everything is not only working fantatically in terms of video, but response time is noticeably improved for everything that I do.
I know I can go create a new user profile and copy the settings etc, but things like this are very disturbing and wondering if anyone has any insight and expertise about this. I'd like to repair the profile if possible just to say I did it but I guess it's ultimately one of those Microsfot features we all have to live with (unfortunately). Anyways any opinions on this would be appreciated.
