Helping people with computers... one answer at a time.
Nine times out of ten, this sort of difficulty in playing videos indicates a problem with the video driver.
I'm running Windows 7, SP1, Home Edition; Acer Aspire laptop. When I stream a video, for example, the Food Network cooking video, YouTube's videos, etc., it will start OK and then the video will freeze and the sound gets stuck on one note. The computer is then locked up; I'm unable to use the mouse or the keyboard and the only way I can power down is to remove the battery and reboot. Can you please help me with this dilemma?
In this excerpt from Answercast #67, I look at a computer that freezes up when playing videos.
So, nine times out of ten when this happens, it is a problem with the video driver.
So, what I would strongly recommend you do is make sure that you have the most recent video drivers for that laptop installed.
That will typically mean heading on out to the Acer website and looking for their support options. Make sure you know the model number of your laptop. Go out there and see if there are updated drivers that are available for it.
Almost always, a heavy use of video in the form of streaming videos (or just running video in general) usually indicates that there's some kind of a hiccup, some kind of a timing problem, some kind of a bug, in the drivers that actually drive the hardware.
Yes, it's possible that there's a hardware issue, but it's just not really that likely. So the very first thing I would do absolutely is to have you go out and make sure you're running the most recent drivers.
The other thing to try (if the drivers don't resolve this) is potentially to at least try a different screen resolution. You're running Windows 7 so you can right-click on an empty area of the desktop; click on Personalize and there you'll see something for screen resolution.
Change it to something else; it doesn't really matter what - as long as it displays on the screen. Typically, it's something smaller than what you have now. It may not look great, but if you determine that streaming video works in that mode, then that's a data point.
Unfortunately, it's probably a data point for a technician to then take a look at exactly what's going on. Still, it sure feels like something to do with the video driver and that's where I'd have you start.
