ROG83, I’m sorry about this situation, but it is important to know that Intel® Extreme Tuning Utility (XTU) was design to work on Intel motherboards only, not on OEM or other system brands devices.
Because it worked for a while, I would recommend you to try installing the previous version again.
If it still not working, you may check if you can restore your computer to the last working state by choosing “System Restore” once you’re in Windows.
Thank you for help !
But unfortunately, my "System Restore" won't go prior to the XTU uninstall...
And apparently no version seem to work.
Hope Intel will solve this problem
ROG83, I’m afraid Intel won’t be able to fix this issue since this software should work only on Intel motherboards.
Please check the Detailed Description at the following link
Do you know if there is any software similar to XTU, in order to slightly and safely OC my CPU i7 4700hq, and to lower its voltage as XTU did ?
