Sorry for the late reply, busy at work.
When you say "It appears that Outlook also hangs", is it Microsoft Outlook? What version or Outlook.com? Any programs installed in your computer hangs as well or just cloud apps and browsing?
Have you tried connecting this one wired directly to the modem/router?
I have another machine sitting right next to it which is Windows 7 Enterprise x64, connected wirelessly, which is having no problems whatsoever.
The machine with the problem is wired directly to the modem/router. I am running Microsoft Office Home and Business 2010. I haven't noticed a problem with Word or Excel when this happens, but I can't say I tested them thoroughly. The next time it hangs I will try to open and use them to see if they are affected.
I just thought of another app that has been impacted. I also run an application from E*Trade, Market Trader, that I believe is java based, but connects real time to the Internet. That hangs as well.
Install Speccy the free edition, keep an eye out on the temps.
Secunia PSI will find all your outdated and the ones that need to be updated.
Uninstall Apps/Programs that are not needed or outdated. You may use Revo Uninstaller (freeware) to uninstall the programs.
Scan your computer using Free SuperAntiSpyware, it won't harm to do this.
Run chkdsk as well.
Another update of your progress will be appreciated.
I found 192 adware tracking cookies and a key logger trojan. They have been removed. I have also deleted the files from the previous user account.
The trojan: "ie8-ie9-recheckfix.exe"
I upgraded my CPU fan about two weeks ago and I have been monitoring the temperature. The new fan brought the temp down around 15 degrees Celsius.
I ran Secunia and it suggested I upgrade from Acrobat 8.1 to v11, $200 later that was done. It also found an issue with MSXML Core Services.
I really don't have apps that I don't use, as I keep an eye on these, but I did deinstall the Dell Docking program
I generally run chkdsk once a day on start up.
I'll continue to monitor the situation.
We running pretty well most of the day and then recently hung. It affected Chrome, Outlook, a Java app. It did not affect Excel, Word, PowerPoint, the Resource Monitor. I had just opened iTunes when it happened and iTunes hung on opening. I looked under CPU on the Resource Monitor and saw that iTunes was waiting on another process. That process was a Network Service. I terminated that service but that didn't resolve the problem for Chrome, or Outlook, but iTunes started working. I re-booted and will monitor
Still having issues. I will go with IE for the time being and not use Chrome and see if things change.
