Dell Vostro 220 Game Graphics Problem

Hi. I recently got a new Dell Vostro 220 with an Intel G45 1GB graphics card. I recently installed "NFS Most Wanted" and was shocked to see some very screwed up graphics. See the screenshots below:

This is how it looks like on default settings (almost everything set on min):

This is how it looks like on max settings (resolution is same though):

This is how it looks like on min settings:

When I start playing on min settings the graphics are fine, but when I reach a high detailed areas I can see some color loss, and on even higher detailed areas It gets blue like the previous images (see screenshot below):

I have all the latest drivers installed. The graphics card is 1 GB and on the site it says that it supports high-graphics games like "Crysis", so I don't see what the problem is...
I have also tested this game on system requirements lab and it passed the test. I also tested games with even better graphics and they also passed the test.....

I would be glad if someone helps me find a solution to this problem, without telling me to buy a new graphics card
