I also had trouble with the latest 22.214.171.12456 driver with display corruption over HDMI and had to roll back to 126.96.36.19980. It's a nuisance that it's now gone from Download Center.
If you can't restore using Windows System Restore, then if you Google "GFX_Win7_8.1_64_188.8.131.5280.zip" there are quite a few download sources ... I'll leave you to pick one that looks trustworthy
Or hopefully Intel will issue a fixed driver soon.
Edit: for reference, my problem was reported here: NUC5i3RYK - Graphics Driver 184.108.40.20656 bugs
