This depends on which hardware subscore dropped.
Most likely, it's due to an updated driver for that item (ex: graphics). Drivers can cause the WEI score for that item to go up and down a tiny bit since the drivers can affect their performance.
Hope this helps some,
sorry for taking long time to replay. it's nvidia gforce gt740m latest update is v 332.21Yep, a new graphics card would do this. If you have not already, you might see if installing the latest drivers for it may be able to help improve it's performance some.
What brand and model is the new graphics card?
i will try it thank you for your helpNo worries. You might see if the 334.67 beta driver may run better.
