Hey - i recently was told by Vista that my hardware had changed from the hardware I had when i bought my computer a few months ago - not true, by the way - and was told to run the system assessment tool again. when I did, my index went down from 3.4 to 3.3, saying that my "gaming graphics" score had changed. However, i still have the same graphics card that my computer came with - the nvidia GeForce 7350 LE. Why did this happen?

i have an HP m8120n with 3 GB DDR2 memory and a Core 2 Quad Q6600 chip running at factory setting (2.4 or 2.66 GHz, i think)
