[Windows 8.1 and Windows 8 support]

Thank you. If it's possible, please turn off Logitech LCD support in AIDA64, and let us know if it makes a difference. Also, if you have any ASRock software installed (e.g. ASRock Extreme Tuner or F-Stream), then please try to uninstall them, to verify if they cause the issues or not.

BTW, what version of Logitech LCD drivers and nVIDIA ForceWare drivers do you have installed?

My system is clean,i dont install ASRock Extreme Tuner or F-Stream,ecc...

The drivers is all the latest:

306.97-desktop-win8-win7-winvista-64bit-international-whql

Logitech Gaming Software 8.35.18

This is not a Windows 8 related issue, but sounds more of an isolated configuration or driver issue. Can you please tell us more about your hardware configuration? Also, are you running Windows 8 RTM Build 9200 64-bit?
