Hi aslander, let’s install the latest driver.

- 32-bit: https://downloadcenter.intel.com/download/24965/Intel-Iris-and-HD-Graphics-Driver-for-Windows-7-8-8-1-32-bit
If the issue persists, does the issue occur with specific video file type(s) and/or video player software? Kindly try different ones.
Thank you joe_intel, it works!
I thought I've downloaded the driver from the CD of my motherboard, but for some reason it seemed not working.
