Black artifacts on videos - new issue

[charlesr]

HD5450 card.

Might my PSU be on the way out? I've started getting loads of black all over videos for a few seconds before they burst back to normal.... small embeded ones as well as full screen.

Is there any way to tell how stressed the PSU is?

What kind of video?

Also artifacts tend to be a graphics card RAM issue.

[charlesr]

YouTube etc.

Or plex from local files

Think HW Monitor tracks things like power drain

Also speedy could be right, I only ever see artefacts when overclocking GPU memory a bit too much.

Installed that app thanks - good stuff.

Power draw seems to be about 20W....
Temp on video card is 60?C (normal for my fanless card).

Looks like this to start with


Then a few seconds later:

You can try to uninstall and reinstall video drivers and/or installed codecs. On Youtube videos, does it happen with all browsers?

[charlesr]

I went to check but now it's all fine in all browsers and media players..... I think I'll reinstall the drivers anyway. Ta.

Late the party but that looks like what happens when a video file has some trouble and certain frames can't be decoded properly/in time. I see that when skipping through videos I'm streaming. It looks like the player is showing movement without the actual images to move. Sometimes it's black like yours, other times the movement morphs whatever frame I was on when I started skipping which gives a groovy effect! Reminds me of texture pop-in in games.

On a side note, it isn't driver-related but I wonder if hardware video acceleration could affect whether it happens or how often.
