Win 7 Problem

[NFarnzy]

Hi everyone,
I have been using Win 7 64bit now since about May, when it first got released. It has really worked well for me and have got alot of use out of it. I did a reformat to kill off some partitions because they was too small for what I needed. I went to reinstall everything, it went well. got the full size partitions back. I have a pair of WD Raptors 150gb. Not in raid, wanted to do something simple and kept them as is. Here is where the issue started, I use Disk Keeper to defrag my HDs, it has always worked well for me, then I went to there site and updated the program and something went wrong , so I uninstalled it and then reinstalled without the update, now what happens is when I am using the administrator account, ( my primary, get tired of the nagging from the UAC ) The programs freeze on the desktop. I cant open a file without getting a new window open and the web browser's all do the same. When I am playing an online game, I wont be able to move in the direction I want to move in, moves me opposite of what I want. The icons on the desktop, all bunch together and I cant move them without moving all of them however if I go to the other account, it is all good, none of that happens. if anyone has any idea of what is going wrong, please advise. If there is a fix rather than a reformat, would be good, I get tired of always reformatting when something goes awry and I cant figure something out. Thank you for anything that may help me figure this out!
