did you build a new system and transfer the old image across?
if so, realistically its best to start fresh....make sure u uninstaleld all the old drivers etc.
if not - clean out all your temp folders, uninstall anything that you dont need, run a disk cleanup and tell it to clean everything..go thru your "my docs" or pretty much ur c: drive and delete anything tha you dont ened, run defragx3..
also - does it also take 2-3mins to shutdown? might be your user hive having greif...you can try this: http://www.microsoft.com/downloads/details...;displaylang=en
