I'll like better understand the issue you have described, please check below:
- What is your operating system version?
- Have you tried downloading Intel(R) drivers?
Does this issue happen when using computer manufacturer's drivers?
I am using Windows 7 Ultimate x64 SP1 (Korean)
and I tried 126.96.36.199.2509(2011-09-07) and 188.8.131.52.2361(2011-04-13) drivers.
