I am using Windos 7 Ultimate N 64 bit. I currently have 4gb of memory , 1.8 tb of hd drive space, Amd 6000. I notice when I shut down my computer it takes 5 minutes to shut it down. I have no problem booting up goes pretty quick. have looked around and can't find anything that may help. I run CC cleaner, Malware bytes, Disk defrag and a few other programs to keep maintenance on my computer. Any ideas or suggestions?
