Thanks ahead of time for any help given! Computer keeps freezing after working for short periods of time. Internet Explorer and Firefox do. I have not used any other programs for extended periods. They slow to a snails pace and then freeze, but eventually respond after a minute or two. The browsers minimize themselves and then maximize. This just started this morning. I looked at the Event Viewer and this is what I believe the problem is, but I'm not that good with computers. Here are the two event ids that i believe are the culpirate: Log Name: Microsoft-Windows-Diagnostics-Performance/Operational Source: Microsoft-Windows-Diagnostics-Performance Date: 8/1/2010 9:29:45 PM Event ID: 501 Task Category: Desktop Window Manager Monitoring Level: Warning Keywords: Event Log User: LOCAL SERVICE Computer: Steven-PC Description: The Desktop Window Manager is experiencing heavy resource contention.

It sounds to me like an issue with your video card and/or video card driver. Windows 7 uses a feature called Windows Aero to give a fancier and more feature-rich feel and look to Windows 7 (and Vista as well). First I would try shutting off this feature to see if that is causing the resource overloads you are having. Here's a link to some instructions on how to do this: http://www.howtogeek.com/howto/windows-vista/disable-aero-on-windows-vista/MCITP: Enterprise Messaging Administrator 2010; MCITP: Enterprise Administrator, MCITP: Server Administrator; MCTS: System Center Data Protection Manager, Configuration; MCTS: Windows 7, Configuration; MCTS: Windows Server Virtualization; MCTS: System Center Virtual Machine Manager 2008, Configuration; MCTS: Windows SharePoint Services 3.0; CompTIA A+/Server+

Hi, Please go to test this issue in Clean Boot, Device Clean Boot and Safe Mode to determine the possible cause. If it works fine in Clean Boot, the root cause can be the third party software. If the issue reoccurs in Clean Boot, but works fine in Safe Mode, the cause can be the disabled hardware drivers. You may narrow down the causes in Device Clean Boot. Device Clean Boot ================= 1. Click Start, type "devmgmt.msc" (without quotation marks) in the Search bar and press Enter. 2. Expand "Sound, video and game controllers". 3. Right click on your sound card and then click "Properties. 4. In the dropdown menu of Device Usage, please choose "Do not use this device (disable)" and click OK. 5. Please use the same method to disable other dubious hardware such as: internal modem, network card and CD-R drive. Please note some devices such as video adapter are not available to be disabled. If the issue persists, please go to Event Viewer to check logon and logoff event, see if any error is relevant. · Event Log ======================== 1. Click "Start", input "eventvwr" (without quotation marks) in the Search bar and press Enter. 2. Right click on "Application" on the left frame, choose "Save Log file As"; in the pop-up window, click to choose the Desktop icon on the left frame, input "app" in the "File name" blank, and then click “Save”. 3. Right click on "System", with the same method, save it as "sys". 4. Locate the two saved log files on the Desktop and send them to us.
