Ok so I tried to post in another thread but never got an answer so I will try and run through what my problem is.
When I leave my computer alone say for 15 minutes most of the time when I come back the computer is frozen and the mouse cursor is not updating properly (like when going from hyperlink showing the hand and finger its not updating back to normal mouse cursor) My CPU usage never gets over 3-5% and memory never gets over 19% so it shouldn't be that. I am having a problem with one particular windows update never actually updating so that may be my problem but I can't get it to work.
Here is the update
Security Update for Microsoft .NET Framework 4 on XP, Server 2003, Vista, Windows 7, Server 2008, Server 2008 R2 for x64 (KB2656351)
Below is my Speccy information and please let me know what else I should put up here to help.
