You just wanna see if we can tune it up a bit? I am thinking that it wont make that much difference but we can give it a go if you wish. Also you can use the intel auto update utility to see if there are any updates for your drivers.Another driver update tool is drivermax.

I doubt that you have the wrong drivers considering where you got them from.So just forget about the unknown device ID log.

That would be my guess a lot of those games depend on a high end graphics card have you tried your games on the lowest settings?

No the drivers are not wrong you can try an update of your graphics driver with drivermax.This is a common problem with intel auto update it is hit or miss so to speak.

No it is saying that you should get the driver from the manufacturers website.

The graphics card is intergrated which means that it is bonded to the motherboard. so that is out of the question.

I doubt that any of that will help you.it seems that you have the latest graphics driver.
