I have something that just slows my computer to a crawl sometimes. Not running anything big. Yesterday all I had running (besides background apps) were Firefox & Windows Explorer and could barely even switch screens.

Nothing showing up in the task manager as hogging CPUs. I have all non-essential services stopped (MySQl & MSSQL) unless I need them.

I made some restore points not long ago, but they disappeared. This is a development mach with a LOT of apps installed, so I really, really do not want to re-install Windows.

So, what I'm looking for are ideas or tools I can use to help diagnose this problem.
The only clues I have is this started right after I

• installed Office 2013 (with Office 2010 still installed as well)
• installed Visual Studio 2012 (also keeping 2010 as a co-install)
• and installed MSSQL 2012 (upgrade from 2008, no co-install)

Also, computer runs fine in Safe Mode. I've just ran out of ideas of what to check.

Any help / suggestions would much appreciated.

Thanks

P.S. I'm running Win 7 Pro (x64). Office is also 64 bit. Visual Studio & MSSQL are 64 bit if that option was available (not sure).
