Video Corruption

[ReddFour]

I have a nVidia 760 and I get this weird video corruption in the likes of Window Media Centre and VLC as shown in the attached screenshot. It's actually often much worse than that example but it gives an idea of what is happening. It doesn't always happen. Sometime I start my PC up and it's fine. Does anyone have any ideas how to solve it?

Do you use a DVI converter? I've seen this when you have to change interface with a hardware plug.

No HDMI to my monitor.

Could you upload/link a larger picture?

[ReddFour]

That is original size.

Search for compression artifacts. Might give a clue.

What's the clue?

This isn't the video file. It's something to do with the video drivers. It flashes on and off (which obviously a screenshot doesn't show) and is always in the same place between reboots of the PC. If I reboot the flashing may occur somewhere else on the screen until I reboot again. I never got this with my AMD card. It only started when I switched to nVidia (which I did a clean install of Windows 7 for).

The desktop and games are fine.

If you're sure about the drivers being the culprit, you may want to remove the driver, boot into safe mode, run a driver cleaner, then re-install in normal mode.

If it happens again, then it might not be the driver.

What Gorion says, there's an nVidia driver sweeper package available free that works great. If you look at your registry a lot of legacy driver references remain after upgrading nVidia drivers and I had a problem last month where my monitor through a DisplayPort interface wouldn't light up on reboot. Cleaned the lot out with DriverSweeper and it's working fine again.

Does the same happen in fullscreen and windowed mode?

What CODEC's are the videos your playing? What has been used to record the video?
