I use home premium 32bit, I can upload this file and you can download and replace to see if this will help... 3.33 MB means you are missing part of it... I will post a link in the next post.
try one more thing (that I can think of) right click desktop, put your mouse over "graphics options" then mouse over "panel fit" and then click full screen (no border)....see if thats it.
if its already chosen then go back to device manager, right click the chipset one that you have (under display adapters) choose "properties" > driver tab, is "roll back driver" an option??
