I currently have a lenovo w500 with switchable graphics. everything was working fine until very recently.
Anyway, after switching from the integrated to discrete graphics card windows aero suddenly stopped working. I tried doing a system restore which worked, but now it's dysfunctional as well.
I also started getting constant chkdsk operations because of a dirty disk. I've run chkdisk c:/r from a windows live CD but i'm still getting said errors.
After updating my display drivers, windows aero worked temporarily until after restarting and a chkdsk operation.
Any idea whats going on?
