Hi, Thanks for posting in Microsoft TechNet forums. I suggest go to test this issue in Safe Mode, Clean Boot and Device Clean Boot to determine the possible cause. 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, would you please upload more minidump files for further research? Collect Minidump Files ================= 1. Click "Start", input "SYSDM.CPL" (without quotation marks) in the “Search” bar and press “Enter”. 2. Switch to the "Advanced" tab and click the "Settings" button under "Startup and Recovery". 3. Under "Write debugging information" section, make sure the "Small memory dump (128KB)" option is selected. 4. Make sure "%SystemRoot%\Minidump" is in the "Small dump directory" open box and click “OK”. If the crash appears again, please refer to the following steps to collect memory dump files: 1. Click “Start”, type “%SystemRoot%\Minidump" (without quotation marks) in “Search” bar and press “Enter”. 2. Go to your Desktop, right-click on it and create a new folder named "Dump". 3. Copy all the memory dump files (looks like [Mini092008-01.dmp]) in Minidump to this folder. 4. Right-click on the Dump folder, click "Send To", and click "Compressed (zipped) Folder". 5. Please send the ZIP file to us.
