Hi
I recently bought a Acer Aspire 5745G but I have a little annoying problem.



As seen on the image, those artifacts appear when the following happens while I'm using the Intel GPU (more battery time, less performance)
- I connect or disconnect the power cable.
- The screen dims (brightness gets decreased).
- The laptop wakes up from sleep.

But when I use the Nvidia GPU (less battery time, more performance) there are no artifacts and everything above works fine.

At first I thought something was wrong so I returned it to the store where I bought it and got a new one. I did a clean install (like before) of Windows 7 installed the latest drivers from Acer's site and discovered that the same thing happens.

If I download the latest drivers from Intel's site and install them the problem is gone. But I cannot switch between the Intel GPU and Nvidia GPU, only the Intel GPU is available). Downloading the latest from Nvidia does not work since the installer does not find my Nvidia card, trying the "auto detect driver" tells me I have to download drivers from the laptop manufacture.

I believe the drivers that comes with the laptop are newer then the ones on Acer's site. I have sent Acer a support email, but no response from them yet.

Anyone with similar problems (have you fixed it)? Or if someone has 5745G laptop that has not had a clean install that can check their driver versions. Mine are:

Intel® Graphics Media Accelerator HD
Driver assembly version: 8.16.11.8899

NVIDIA GeForce GT 330M
Driver assembly version: 8.16.11.8899
