NVIDIA GeForce 310M - problems with WEI and video quality?

I bought a new laptop - ACER 5745G.

After the initial Windows 7 64bit installation my scores were 6.6, 5.9, 5.9, 6.0 and only the Graphics for Areo a 4.9. Since I mostly want to use this laptop for watching HD videos, I figured those are scores aren't low and was satisfied. However, after automatic updates were installed all scores went down at least 1.0 point.

I tried installing a driver from NVIDIA's website, I tried changing performance settings but nothing made it better - instead in the end the graphics for aero score became 3.7.

I used system restore to get the laptop back to the date before some automatic updates were installed but I don't think I can make it stay like this forever.

Is this a bad graphics card? Am I expecting a score that is too high? And most importantly - what settings do I need to have in order to get the best video quality?


Thank you in advance!
