Hi, It’s hard to say upgrading to Windows Server 2008 R2 SP1 can fix the blue screen before knowing the root cause. Generally, you may update BIOS and other hardware drivers first. If it does not work, you may analyze them with Debugging Tools by yourself. You can install it and it’s Symbol Packages from the following link: http://www.microsoft.com/whdc/Devtools/Debugging/default.mspx WinDbg will tell you the possible cause. For more information, please read Microsoft KB Article: How to read the small memory dump files that Windows creates for debugging http://support.microsoft.com/kb/315263 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 Blue Screen 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.
