Hi, My Win7 install runs well, but I get occasional reboots. The event viewer shows this before the reboot: The computer has rebooted from a bugcheck. The bugcheck was: 0x0000007a (0xfffff6fb80000000, 0xffffffffc000000e, 0x00000001293dd880, 0xfffff70000000000). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 061411-12074-01. The dump is 476MB (I have 4GB of RAM, is this not an entire dump?). I had some NTFS warnings just before the crash: The description for Event ID 50 from source Ntfs cannot be found... \Device\HarddiskVolumeShadowCopy5 How can I tell which disk it relates to? My boot disk is an SSD. Thanks in advance for all your support.

Hi, For bugcheck 0x7a, please refer this article: http://msdn.microsoft.com/en-us/library/ff559211(v=VS.85).aspx Also you can collect mini dump for me to analyze: 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. 4. Right-click on the Dump folder, click "Send To", and click "Compressed (zipped) Folder". 5. Upload to SkyDrive. Regards, Leo HuangPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
