Windows 7 borders appear corrupted on my Lenovo T500 Thinkpad

[talkdotcom]

It presently has 3 gigs of ram, I am going to increase it to the max. of 8 GB as I was told in the past it can increase the acceleration. The computer has Intel R ICH9M/M-E Family 4 port AHCI Controller-2929. Display is Mobile Intel R 4 Series Express Chipset Family (Display Adapter) 2X.
The chipset above has the newest driver. What else can I do to get rid of this issue? Thanks very much!
