Anyway, I was wondering if I could get some insight on a problem I've got here. I noticed in an older thread, this guy was having a problem kind of similar to mine here, but it doesn't seem any of the suggested solutions worked.

I recently made a slight upgrade from a GeForce MX440 to a Radeon 9550 since my brother got a new card and didn't need the Radeon.
However, my problem is kind of backwards. I haven't noticed any decrease in gameplay. Instead, I've noticed a very annoying lag between minimizing/maximizing windows, slower web page loading, slow scrolling up/down of webpages, etc. all of which weren't there with the MX440.
I've uninstalled all the previous nVidia drivers/software and un/reinstalled the most up to date ATI drivers from their website about 4 times now, with no results. I guess it would make more sense if I experienced worse gameplay, but since that's not the case, this is kinda weird.

Any advice/insight would be greatly appreciated. I'm itching to just put the MX440 back in and forget about the whole thing.
